Trekking bike bought second hand in 2017. Seller confirmed it is this one www.kross.pl/en/2012/trans-alp (archive) but male version (now shown clearly on website, but both exist).
2024-02: noticed pump was finally stolen. Certainly the drug addicts can't even get 1 dollar for it. TODO identify and rebuy.
2023-08: redoing drivetrain: Shimano HG51 8 Speed cassette 11-32t, Shimano HG40 8-speed chain, Shimano FC-M311 48T/38T/28T 175mm cranckset, first two from Amazon, last from www.santafixie.co.uk/shimano-altus-fc-m311-175-mm-crankset-black.html does not include elivery but still was the cheapest I could find, 4 pounds. Likely not worth the signup effort, but we gotta fight Amazon when they are beaten on prices for moral reasons...
2023-03: Rebuying HG40 8 speed chain 116L, Never paid attention to link counts before, dude said I might have to remove two. There are three options 114L, 116L and 118L
2022-08 I can't take the cassette out anymore again... first tried to remove correct side, didn't manage. Tried the other side, wrong one, and it ticked about 10 times. Then saw video, and initial side was correct. That piece is extremely asymmetric... it is a problem.
2022-08: front mudgard was unbearably noisy, put on the new one I had bought long ago. Asked bike shope person to cut 2.5cm from each metal stick which was way way too long, measured this quickly by placing the new one on top of the new one without attaching. After I got home, noticed it was still too long. At home I noticed one was better than the other, this is because the attach point is not centric on the wheel like on the back, so it requires different cuts. Going to cut again 1cm on one side, 2cm on the other, so total from start would have been 3.5cm and 4.5cm.
Got a puncture on back tire, perfect little point, but on the interior. Could not determine cause. Noticed that the "thumbs up" patch sets that came with the COZYROOMY tire lever were kind of crap, barely held. Made test to see if will deflat or not. Bought a Weldtite cure-c-cure puncture repair kit instead: www.amazon.co.uk/dp/B003GBBQGM. Looks good.
seatpost making clicking noises again... seems to be from collar area, since already changed several time seatpost. Went to shop and they: 1) cleaned surfaces with rag and some cleaning oil 2) aligned hole in tighenener thing with that of frame 3) tightened well. Let's see. People also recommend greasing the clamp bolt:
2022-08: Topeak Aero Wedge saddle bag stolen in city center, bought many years ago, don't have exact product. Quite incredible that something so cheap, unsellable, and unusable except by a sportsperson would be stolen. Looks like this: archive.ph/wip/atSJK, not like the identically named 2022 produc with two zippers. Rebuying the new two zipper model: www.wiggle.co.uk/topeak-aero-wedge-buckle-medium-saddle-bag Edit: was wrong one, medium is humongous, likely wanted small 18 - 11 - 8.5 instead, two zipper is not a new model, it is a medium vs small issue rather. Exchanged for the small.
Rebuying HG40 8 speed chain.
2022-05: weighed the bicycle for the first time. 17 kg without any optionals
Broke front part of front mudgard when trying to put bicycle in bike bag without front wheel. Fuck. Surprisingly brittle.
2022-04: could not remove pedals with small 10cm wrench, preparing for trip. Took it to mechanic, they removed without any problem with a Park Tool PW-4, and greased. Glad to see it was not stuck. After that, I was able to remove myself with my 10cm non specialized wrench. Considering getting the Park Tool PW-5 instead of PW-4 which is half the price and just a bit less long. OK Bought it.
2022-03: changed chain after it reached the limit. Very slight slippage on gear 6 as usual, but did not seem enough to require changing the cassette, but rebuying it as soon as I find a good price for next chain for sure, rebuying Shimano HG51 8 Speed 11-32t. OMG it is so expensive now, stocks our out everywhere!
Besides that, have been hearing some noises from the seat post that are worrying me... it never ends... rebuying a Brand-X Layback Seatpost 27.2 diameter 350mm length post to debug.
Also getting Shimano SM-SH56 cleat, there was a deal with 3 pairs so getting 3 pairs now.
2021-11: seatpost making noises again... going to try a Brand-X Layback Seatpost 27.2 diameter, which does not have the useless suspension, and has a double bolt system, and sells on wiggle which is a good sign.
2021-11: 3 days after a ride, tire was empty, thought it was vandalism. Inspected, could not see any issues, did a 75km ride, and left a gain, and again it lost air quickly. Opened up tire, and found a thorn of some plant pierced inside, almost invisible from the outside. It also feels like the thorn stuck in place and reduced the rate of air loss, after removing the tube it lost air quite quickly. Could not fully remove thorn, can still feel it with my finger, but too well stuck in tire, but I don't think it is enough to pierce again, I just put a patch set on top of it, and new tube Schwalbe 700C 28'' AV 17, got two of those.
2021-11: trickling noise coming from front wheel. Going to get a new one without the generator which I have use anyways and see if it solves it: www.tredz.co.uk/.M-Part-Shimano-Deore-Hub-on-Mavic-A319-700c-Rim-Complete-Wheel_35638.htm M Part Shimano Deore Hub On Mavic A319 700c Rim Complete Wheel. Getting www.amazon.com/dp/B004TGL57S Raleigh TRT701 Wheel Rim Tape - Red, 700c
2021-10: changed chain for new one. Found out that the one I bought did not have a quicklink... Also, it did not come in the original package, but in a sealed plastic bag, presumably to reduce shipping costs. www.amazon.com/dp/B004XVQ2O0 have to be more careful next time. Lost the Shimano 500ml bottle, was strapped on back carrier of bike, but not safe enough, and I went through rough terrain. Had seen it fall off once before another time, but very rare. When I noticed, had no idea where it had fallen off and didn't go back for it. Buying:
Fit perfectly. Luckily Amazon made me buy two Versamounts, because I needed to use one for each bottle, as the holes on the frame were too close to the bottom and made it impossible to fit both otherwise.
2021-09-05: chain reached 0.75, rebuying HG40 8. Also buying second set of break pads, front is gone, and back almost, gonna swap both at once.
2021-08: back side of teeth of seat post wore off, and the seat is rotating vertically. Identification: markings: ELC (maybe middle letter worn off). 27.2 diameter / 350, 350 is the length from Googling. Has a simple shock absorber system and a single pin to attach the seat. OK, something very similar or the same: www.amazon.com/dp/B08N9ZTD22. BESNIN Suspension seatpost. Full markings are: HARD MDU INSIDE under seat clamp, these match exactly. Tube markings are a bit different.
2021-08: noticed that there was a stone stuck inside back tire. Luckily didn't puncture. TODO was it in the same place as the previous puncture? Not far from Schwalbe mark. Rebuying... and answering bicycles.stackexchange.com/questions/9827/when-should-you-replace-tires-after-getting-a-flat Going to buy Shoe Goo as well to see if it works: www.amazon.co.uk/Shoe-Goo-Crystal-Permanent-Adhesive/dp/B08P5V9GQV
2021-08-12: after putting new chain on, if I step hard on pedal on 6th gear, by far the most used, it skips. Seems to be the same symptom as 2020-12 when cassette was worn off, as the shifting itself seems fine. bicycles.stackexchange.com/questions/8378/difference-between-shimano-hg51-8-speed-cassette-and-shimano-hg50-8-speed-casset says hg51 is compatible, so getting that newer model. 11-34t was much more expensive/less common than 11-32, so getting 11-32. Managed to install it without any problems.
2021-08: bought Shimano HG40 8 speed chain and put it on bike
2021-07:
  • rear shift cable snapped inside shifter during rid, same as 2020-10, same symptom that could never index higher tension gears well bought new cable
  • chain reached 0.75+
  • tried to put front mudgard on, but several problems on this one. The screws needed are wider than those that come. Could keep old ones. But then on top of that, the metal bars are too long and would need cutting about 2 cm, so keeping the old front mudgard for now, which is working perfectly.
2021-06-05: finally removed the old bottom bracket and installed installed the one I had bought a few months back. What triggered this was the clicking noise back again. It appears that the noise got louder with the heat. The clicking noise went away after changing the new bottom bracket. The old bracket seemed fine after inspecting it closely after removal. There was a bit of dirt/earth inside, and some small chippings came out of one side, not sure if from BB or from the frame itself. There are still some other much less loud noises left however, but they are likely a different source, and not a big issue. The clicking noise: www.youtube.com/watch?v=rXBdPg1LhQU
2021-05: got the first flat tire ever on the back wheel! A perfectly shaped pointed triangular rock slotted perfectly into the thread and managed to perforate the inner tube. Managed to patch it up perfectly on the road, 2 hours away from home! The inside of the tire is basically intact, so I'm going to keep using it. The next day I put back an old intact inner tube I had replaced preemptively earlier on with this new one that was punctured.
2021-04: put on the Bluemels mudgard on the back. It wasn't hard, and their system seems quite easy to adjust. Chain reached 1.0 stretch, gotta get a new one.
2021-03: clicking noise when pedalling strong driving me crazy. Likely bottom bracket: bicycles.stackexchange.com/questions/41149/something-clicks-while-pedaling or maybe pedal. Re-buying the exact same Shimano BB-UN55 Bottom Bracket - Silver, 68-118: www.ebay.co.uk/itm/224364037969
2021-03: buying mudgard replacement, going for: SKS Bluemels Shiny 45 mm 28" Mudguard Set Silver www.deporvillage.net/sks-bluemels-shiny-45-mm-28-mudguard-set-silver 28 pounds with delivery, which looks like the most similar to the old one. Partially choosing that seller because they are the only ones capable of using the precise product name as shown on the SKS website so I'm sure what I'm getting. It does not have flaps though. But flaps fall off and get lost, so fuck it. SKS range: www.sks-germany.com/en/products/bluemels-series/
2021-03-07:
Only for side wall machined rims. Performs especially well in wet conditions and may pass DIN standard. Tend to be low noise, low rim wear and fade.
It appears that "non-machined rims" don't exist anymore: www.tetongravity.com/forums/showthread.php/183806-How-important-are-machine-sidewalls-vs-non-machined
2021-03-07: one of the wires of the rear mudguard broke due to vibrations! It still kind of works, but gotta get a new one.
2021-02-20: replaced new wheel. Worked fine. Also measured chain stretch between 0.5 and 0.75.
2021-02-14: in preparation for wheel switch, also getting www.wiggle.co.uk/shimano-m-system-m600-pair-of-brake-blocks Shimano M-System M600 Pair Of Brake Blocks. More precise markings: M70T3 Deore LX, AL (aluminium) si.shimano.com/pdfs/ev/EV-BR-SHOE-ATB2-1414L.pdf Reads: "Performs especially well in wet conditions and may pass DIN standards. Gives off less noise, but the pad is heavier, faster rim wear and tends to fade. "
2021-02-11: tried to put the new wheel in. Made a few discoveries:
  • I can't take the cassette out anymore again, even though I put it on myself, and the day I put it on, I took it off once to check if I could, so rebuying Shimano Claris CS-HG50-8 11-34t www.ebay.co.uk/p/2252255352, and if I ever have to take the old one off, I'll take it to the store again
  • the tire on the old wheel was on the reverse direction, had been ridden for a very long time like that, and the threads are extremely worn
  • after making insane efforts earlier to put the tire on the wheel, and knowing about directionality, when I actually took it down I noticed I had at some point of my suffering swapped sides and put it on the wrong way in......
  • I weighted the wheel for fun, assembled with unfilled tire and without the cassette was about 2.5kg
2021-01: ETC Rim Tape 700 40C for the new wheel. No packaging, but possibly: www.amazon.co.uk/dp/B0063HIIOY
2021-01: moved the saddle forward a bit to 1.8cm was still feeling scapulas before, now seems perfect. Not much effort on hamstrings, but I don't know how to fix both, and not having pain is more important
2020-12: moved the saddle forward back to 2cm, was feeling too much pressure on lower back, and on previous ride, the most tired part of body was behind scapulas, so presumably due to overreach. Felt immediately better.
2020-12-22: felt like rear hub had a bit of friction, can't fix vibration, going to try the buying a new whole wheel:
2020-12-21: put in the new cassette, chainring and chain. Shifting is amazing once again. When pedalling strong on the test run it felt like something on the back hub was vibrating... gotta debug that. Maybe not enough force on closing the cassette?
2020-12-20: tried to replace entire drive chain after over stretched chain destroyed teeth. Chainring and pedals came off nicely, but cassette was stuck, but I took it to the shop and they managed: bicycles.stackexchange.com/questions/18465/how-can-i-remove-a-stuck-rear-cassette/74041#74041
2020-12: moved saddle back to 2.5cm mark to try and get more hamstring action, but back started hurting. Moved to 2.2cm half way through ride, and it seemed perfect.
2020-12: moved seat post down after www.youtube.com/watch?v=FNGMRtJ5LIc mentioned that saddle too high causes greater asymmetries which I had felt. With dhb Dorica MTB Shoe (2020-12) with cleats straight on 2-mark. First down 15mm from max, but felt really too low. Then down only 7.5mm, and felt great, possibly better than before.
2020-12: moved 2020-04 Giro Rumble VR Off Road Shoe cleats all the way back, and turned the left one a bit outward to better fit let. Got more tired on hamstrings than on quads now, gotta improve that later on maybe for better balance.
2020-12: put more WD-40 on front shifter. Let it dry, then "WD-40 Bike, All Conditions Lube Bicycle". After next four hour ride, shift to 3rd was still working perfectly. Found the culprit.
Put back the rear mudguard. Wheel not hitting it for now. Lost the extra appended protector thingy, was sure I saw it during installation, so maybe it just fell off during next ride? Can't find it at home. Does not make much different for me, might help others behind me though.
2020-12-05: 4 hour ride, very wet and dirty, on start could get into third perfectly, but at end couldn't anymore!!! So it must have been an issue with lubrication on the bottom shift mechanism.
2020-12-01:
  • test rode 3rd gear shift, completely smooth now!
  • put back the new saddle Selle Royal Scientia, and inspired by www.youtube.com/watch?v=ZX3fKolI25Q moved the saddle to 2cm position because I had never felt my hamstrings. It did feel much better! I felt my hamstrigs more, and butt took much longer to get soggy, maybe only around 2 hour mark! Started feeling lower back more though.
2020-11-30:
  • fixed the can't get into 3rd gear problem. Did the following:
    • without cable tension, it changed easily
    • sprayed HD40 on shifter and hinges near bottom bracket
    • still didn't shift
    • reduced tension. This made me manage to change to the 3rd. It must be highlighted how sensitive this was to tension. 5 quarter screws on the shifter barrel were the difference between being able to shift or not
    • one more thing Ciro noticed, is that he had possibly previously held up the front gear before attaching the cable, therefore possibly overly tensioning it. It might be better to just instead pull the end of the cable with a pair of pliers to remove slack, but wihtout making the gear move up, that is enough. Then finish tuning on the shifter arrel adjuster
    • then since everything was out and ready, also changed shift cable just in case. The new one had a bit less friction, but not a lot less, so it did not feel like it was what solved the problem
  • also better inspected the chainrings. Middle one is visibly worn due to the century old chain, even more so than the teeth of the cassettes on the back.. so here we go again, more Shimano FC-M311: www.bikeparts.co.uk/products/shimano-fc-m311-altus-square-taper-chainset-48-38-28t-with-chainguard-175-mm Can't find how to buy just chainring itself.
2020-11-28: can't stand slippage anymore, going to change cassette too, rebuying Shimano Claris CS-HG50-8 11-34t: www.ebay.co.uk/p/2252255352 20 pounds
2020-11-26: left hand large gear almost impossibly hard to switch to largest gear. The gear switches on chainring, but it won't click and stay in place, related: bicycles.stackexchange.com/questions/46172/front-shifter-wont-shift-into-3rd
2020-11-22: put back old saddle, one inch from back, did 6 hour ride, it is more comfortable than new one. Butt was soggy at some points, but much less than new saddle.
2020-11-19: noticed that chain slips if I pedal very strongly, and especially if I try to stand up: bicycles.stackexchange.com/questions/7928/why-does-my-gear-slip-when-going-uphill-standing Does not happen on the largest chainring. Have to check the smallest one, as it is harder to check there. Took to shop, they said chain worn out with tool measurement, and cassette worn out.
Bought Shimano CN-HG71 8 speed chain 19 pounds, with quicklink: bike.shimano.com/en-EU/product/component/city---trekking-e-bike-e6100-series/CN-HG71.html | bike.shimano.com/en-EU/product/component/city---trekking-e-bike-e6100-series/CN-HG71.html, it is from the Acera line. The price in-store was good, on Amazon Prime, would have been 27 pounds! www.amazon.co.uk/dp/B00JJWR12U There were two chain options, a cheaper 12 pound one, and the more expensive. TODO difference? Maybe the cheap one is CN-HG40, which is from the Tourney line?
I inspected the cassette myself later on, but it did not appear significantly worn out in my newbie opinion.
2020-11-08: used park Tool PAW-12 adjustable wrench and park Tool BBT-22 to remove bottom bracket to debug noise. After putting everything together, it seemed gone on a very short test ride. The bottom bracket itself seemed fine. There was a bit of dirt, but didn't seem critical. What felt more off was that the drive side cranck arm came off much more easily than the non-drive side one, suggesting it was not tight enough. www.youtube.com/watch?v=cPQyQnNdews "Crank Removal and Installation - Three Piece Crankset (Square Spindle, ISIS, Octalink)" by Park Tool (2015) suggests that this is a common cause of noise, so maybe removing the bottom bracket wasn't needed after all this time. But it's done at least.
2020-11-05
  • moved saddle backwards a bit to 1 cm mark, was feeling like butt was falling off the back a bit at 0 cm. After this, it felt better, but still a bit mushy after 4 hour ride
  • been hearing a clicking noise when pedalling, left foot at about 7 o'clock. Going to open it up.
2020-10-04 bought a new inner shift cable for the rear derailleur from bike shop, bulk without visible branding. The plastic shifter casing screw was stripped, could not get it off. OMG I had done that just yesterday on the road for the diagnosis! How is it possible? So soft!!!! I just proped the plastic open with a flat screw driver and managed to insert the cable. However, the previous problem still remains: I can't get smooth shift to faster gears on the rear.
2020-10-03 was having rear shifting issues for a while, and today it stopped working completely. Opened and noticed that the shift cable had ruptured inside the shifter!!! Related: bicycles.stackexchange.com/questions/40536/shifter-cable-broke-down-misuse-lack-of-maintenance-shifter-or-regular-occurr This has been only 11 months since last change.
2020-08: buying Selle Royal Scientia M2 saddle: www.selleroyal.com/en/scientia-m-2 based on 60 degree riding position and 110mm sitbone distance Ciro Santilli's body. Had felt a little bit of pain on butt muscle but it passed. But also noticed that the UNICLO shorts ripped a bit, and it might be due to the terrible state of the saddle. Felt good on first ride around the block. Harder than previous, and narrower. Feels higher quality and better fitting.
2020-06-06: replaced front brake pads with the Jagire ones previously bought (one pair already been put on rear brakes)
2020-04-19: tried to remove left pedal again with 2020-04 DECARETA Pedal Spanner, put more force, and the tool itself actually got dented and started spinning freely around the pedal. I give up, will change crank arm. Can't find just the left crank arm, and not sure if 170/175, so just buying the entire thing: Shimano Altus FC-M311 Crank set 48T/38T/28T with chaingard: si.shimano.com/pdfs/si/SI-0094A-001-ENG.pdf | si.shimano.com/pdfs/ev/EV-FC-M311-2675A.pdf | www.deporvillage.net/shimano-altus-m311-175mm-78-speed-chain-set-483828-black at 175mm which is the correct one for my height as mentioned at: www.youtube.com/watch?v=vUygkHlcVMQ
2020-04: bought Shimano Deore PD-M324 pedals in preparation for flat to SPD switch: bike.shimano.com/en-EU/product/component/deore-t6000/PD-M324.html (archive) | www.wiggle.co.uk/shimano-m324-combination-pedals, since I'll remove the pedals at somepoint anyways, first learnt at: bicycles.stackexchange.com/questions/30662/can-i-use-normal-shoes-trainers-with-clipless-pedals/30720#30720 can be used with normal shoes too. SPD/plataform double side chosen to so I can both commute with on regular shoes and ride further for sport with SPD shoes. Cleat type: SM-SH56. Praying to God that the thread size is universal as mentioned at: bicycles.stackexchange.com/questions/10162/whats-difference-between-1-2-and-9-16-inch-pedals When they arrived noticed they felt quite heavy! 533g. Let's see. The non double sided is 455g though: www.wiggle.co.uk/shimano-m530-mtb-spd-trail-pedals/. And a full roadie one like PD-RS500 SPD-SL weights 320g.
2020-04: attempted to use 2020-04 DECARETA Pedal Spanner to remove left pedal that would not come off with generic short wrench and has been clicking a bit for several months, and now sometimes appears to do false spins! The think must be completely destroyed. Failed, too hard.
2020-04: was trying to remove left pedal with short wrench I had, impossible. Later noticed that the kick up stand was a bit bent! Tried to turn it around, but did not manage to make it improve much. Later during a ride, the new position was too close to the spokes, and started to hit the spokes! When I got home, tried to remove the fucking kickstand, but it had a flat bolt in a deep place between the rear tubes, and I couldn't do it with my simple wrenches. Went to bike shop next day, and they removed it, likely with a deep wrench. The piece was thrown away.
2020-03: finally installed the new derailleur after long suffering, including new cables and casing on front and back derailleurs and on back brake. Took 3 1-2 hour sessions, but it became amazing.
2020-03: screw on left shifter (yes, the bloody screw) broke when trying to open it to take out cable. Buying left and right since the right one was broken from previous fall. www.amazon.co.uk/dp/B073XQ8J78 SHIMANO ST-EF65-8 EZI FIRE STI SHIFTERS 24 SPEED (3 x 8), 25 pounds si.shimano.com/pdfs/ev/EV-ST-EF65-9R4-3257B.pdf
2020-02: Bought unbranded bike bell sold in bulk from bike shop, 1.50 pound. Markings: SX. Old bell made louder sound. This type of simple mechanism: www.amazon.co.uk/dp/B00GZ3TFFM
2020-01-13: Parked on city center, shitty low diagonal place, crowded. When came back, bike on floor, had dropped hard since front wheel twisted on axis, untwisted with leg. When got home, noticed that right gear shifter was half coming off. Later found out that the piece broken on one of the screws, hanging only by the other screw. Next day morning, noticed that the bell had come off, and was lost, went back on evening but obviously could not find it.
2019-11: Jagire brake pads 2x V 11.50 pounds: jagwire.com/products/brake-pads/cross-rim-brake-pads (archive)

2019-07-26: the front crank was sometimes making loud cracking noises when I pedalled hard.

2019-08: front mudguards were making too much noise, cannot find brand. Removed them. Then in 2019-10 rain started, and I bought a new one.
2019-06-30: fill tires, using 90PSI, was TODO
2019-06-20: right gear wire broke, when opened for fixing was rusty near hand shifter
2019-04-07: fill tires, using 90PSI, was 40PSI. Also on Giant Flourish.
2019-03-30: repair bearings back wheel, true back wheel, remove rust from chain. Result: 50 pounds:
Tick on back wheel stopped. Back brake did not get better. Gears not improved. Rust remained, was told too hard to remove, and not on teeth, so should not matter.
2018-09-02: spoke www.dtswiss.com/en/products/spokes-nipples/spokes/dt-champion/ + minor brake work 41 pounds full work
2018: front tire blew up and was replaced by TODO.
2017: bought, specs:
Bottom bracket: TODO, have a picture after it broke later on and was removed by shop, but did not catch full markings, visible: JIS DIN EN-14777. JIS stands for Japanese Industry Standard (JIS), related: www.velodrome.shop/square-taper-jis/iso/
Saddle: completely destroyed when he decided to identify it for replacement in 2020. Website said "Selle Royal Freedom Royalgel". Markings (badly worn out): "yalgel", freeDom inscribed on saddle, so that's it.
Frame markings: Trekking (two stylized trees on left, one with two triangles and the other 3 triangles), Frame Size: M. Feels more or less the right size for me. Maybe L would be better, as my butt tends to go off the back of the saddle, which I always cranck to the most backward position possible. Markings under bottom bracket: on metal: LY2B 016042 KROSS EN1746. On a sticker, badly worn off: K828130 2?Z018 0004.
Gear shifters: don't know exact model since could not find markings (fuck you Shimano?) but from photos online, seems to be one of the ST-EF* family EZ FIRE, e.g. ST-EF65-8 or ST-EF500.
Back wheel: quick release.
Front wheel: no quick release, wrench size 15mm.
Back tire: Schwalbe Marathon Plus Tour 42-622 (28 x 1.60, 700x40C) www.schwalbe.com/en/unplattbar.html (archive)) Puncture resistant.
Back hub: Shimano FH-RM30, so possibly FH-RM30-8-QR mentioned at productinfo.shimano.com/download?path=pdfs/archive/2010_SPECIFICATION.pdf
Rear rim markings: Mavic, A319, Made in France, inserted in 36 hole marking, therefore presumably shop.mavic.com/en-gb/a-319-j24500.html#1028=3283&1035=3501 Aluminium alloy 6106
Back light: AXA Basta Ray LED Rear Light. Markings read: "basta X-Ray Steady STANDLICHT Z K 257 TP RBi 1017". Powered either by 2 AAA bareies in series or by the front hub dynamo: www.bike24.com/p213276.html | web.archive.org/web/20190821070347/https://www.bike24.com/p213276.html
Front tire: did not take note, was later changed.
Front light: AXA Sprint 10 Switch LED Front Light www.bike24.com/p213267.html Wire connector for back light: "Crimp Quick Disconnect Terminals". Tried 2.5mm but too large, size refers to each left/right wrinkle.
Grips: Herrmans Primergo, looks like this: www.amazon.co.uk/dp/B01LZSJ30Q
Pedal: flat/platform crap :-) Markings: "FP-910", exactly like the photo: www.ebay.co.uk/i/114124689225 (archive) but can't find the brand, very generic.
Crankset: markings "Shimano", "FC-M311", "Hyperdrive", "Dual SiS index", from Google part of Altus: si.shimano.com/pdfs/ev/EV-FC-M311-2675A.pdf (archive). There are two possible tooth counts, I counted 48T on largest, so it is the 48/38/28 one. There are two arm sizes though, 170mm vs 175mm, not sure which one mine is, very hard to measure, I think it was 170mm. Installation at: si.shimano.com/pdfs/si/SI-0094A-001-ENG.pdf (archive) says to use "8 mm Allen key or a cotterless crank extractor (TL-FC10)". Identification: youtu.be/VMV-SOIhM2c?t=258 "Three Piece Crank of type Square Tapered Spin"
Front derailleur: markings Shimano Altus, 66-69 degrees, blue circle with two balls hyperdrive logo on top. Possibly Shimano Altus Front Derailleur FD-M310: si.shimano.com/pdfs/ev/EV-FD-M310-2676B.pdf
Mudguards: markings "Orion"
Stem: it is a "adjustable quill style" stem, comparable to this one: www.youtube.com/watch?v=Tj_xaQ-o88o but not exactly the same thing. Another comparable one: www.amazon.co.uk/Raleigh-GNJ251-Adjustable-Quill-Handlebar/dp/B004XVPVI8/ Another: www.youtube.com/watch?v=7aXu2J3m5ws very close to as shown on that video.

  • battery life:
    • 2023-04: on-browser streaming + light browsing on Ubuntu 22.10: about 2h45. Too low! Gotta try buying a new battery.
  • 2022-01-04 updated firmward after noticing that ubuntu 21.10 does not wake up from suspend seemed to happen every time when not connected to external power. dmidecode diff excerpt:
     BIOS Information
        Vendor: LENOVO
-       Version: N1UET40W (1.14 )
-       Release Date: 09/28/2017
+       Version: N1UET71W (1.45 )
+       Release Date: 07/18/2018
    used the "Ubuntu Software" GUI as mentioned at: support.lenovo.com/gb/en/solutions/ht510810-how-to-do-software-updates-linux. Kudos for making this accessible to newbs.
    After doing that, another update became available to: 0.1.56, clicked it and was much faster than the previous one, and didn't auto reboot. After manual reboot, dmidecode diffed again:
     BIOS Information
        Vendor: LENOVO
-       Version: N1UET71W (1.45 )
-       Release Date: 07/18/2018
+       Version: N1UET82W (1.56 )
+       Release Date: 08/12/2021
    plus a bunch of other lines.
  • 2021-06-05 upgraded to Ubuntu 21.04 with a clean install from an ISO. Selected
    • "Minimal installation"
    • "Erase disk and install Ubuntu". Notably, this erased the Microsoft Windows that came with the computer and was never used not even once
    • "Erase disk ans use ZFS"
    • Encrypt the new Ubuntu installation for security
    After this, the GUI felt fast, who would have thought that erasing a bunch of stuff would make the system faster!

    which gives an idea of how the above map to mountpoints.
    Had two GUI freezes since installation, a fixed images shows no matter what I do, possibly graphics only, but impossible to tell (next time I'll try SSH access). No Nvidia drivers installed yet.
2020-06-06: dropped some lemon juice on the bottom left of touchpad. Bottom left button not working anymore... I'm an idiot. There are many other alternatives, but very aggravating, I'll replace it for sure. Can't find the exact replacement part or any videos showing its replacement online easliy, dang. For the T430: www.youtube.com/watch?v=F3lzV9uXRjU Asked at: forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile-Workstations/P51-left-bottom-button-below-trackpad-mouse-left-click-stopped-working-possible-to-replace/m-p/5019903 Also I could not access it because you need to remove the HDD first: www.youtube.com/watch?v=5Klawxc7T_Y and I can't pull it out even with considerable force, unlike in the video... And OMG, those button caps are impossible to re-install once removed!!! Then when I put the whole thing back together, the upper buttons were not working anymore. FUUUUUUUUCK. When first opening I pulled on it without properly removing the cap and it came off, but it didn't look broken in any way and I put it back in. Keyboard works thank God, so right black connector is fine, left white one oppears to be the one for upper keys and trackpoint, both of which stopped working. The hardware manual confirms that they are both part of the same device, so basically a mouse :-) TODO can it be bought separately from te keyboard? Doesn't look like it, photo of keyboard part includes those buttons. The manual also confirms that the bottom buttons are one device with the trackpad "trackpad with buttons", thus forming the second entire mouse.
2019-04-17: popup asking about "ThinkPad P51 Management Engine Update" from from 182.29.3287 to 184.60.3561, said yes.

DAPLink Firmware - see https://mbed.com/daplink
Version: 0234
Build:   Oct 12 2015 14:53:22
2022-10-14: stopped being able to connect to Ubuntu 22.04. Was trying to do a UART video demo, connected USB, disconnected, connected, disconnected several times on different filming attempts. Was working some of the time, Ubuntu did recognize it, I even saw UART output for sure, but was a bit unstable. But then at one point it just stopped getting recognized by Ubuntu 100% of the time. The board is still being powered by USB, and the previously flashed program still runs, but nothing showed on sudo dmesg -w at all, and I can't reprogram it!
A day later, managed to get tit to connect once more with a different cable, but just once!

Cool data embedded in the Bitcoin blockchain / AtomSea & EMBII Updated 2025-07-16
View more
"AtomSea & EMBII" refers to an upload system for various media types includeing text, images, HTML pages and audio.
The official name used by its creators for the protocol is P2FK (Pay To Future Key).
The name "AtomSea & EMBII" is a reference to the online handles of its creators. That string appears to be added as padding in the protocol and is therefore visible repeatebly in the blockchain, though it is sometimes cut up a bit. The following online profiles of the creators feel authentic:
Tried saying hi to them at: twitter.com/cirosantilli/status/1382080760774033415 and they replied: twitter.com/AllenVandever/status/1563964396656812034
The feature-set of their protocol is impressive:
Basically they've created a fully descentralized Bitcoin-based social media. Their system is basically a sligly more clunky superset of Ordinal ruleset inscriptions, just way older and way less known for whatever reason.
Each P2FK inscription is done over P2FKH payloads. Each inscription a toplevel transaction which links to other transactions. All the linked transactions together make up the payload. The most common payload type is a text plus image, as is the case of Nelson-Mandela.jpg, which can be seen at bitfossil.com/78f0e6de0ce007f4dd4a09085e649d7e354f70bc7da06d697b167f353f115b8e/ where 78f0e6de0ce007f4dd4a09085e649d7e354f70bc7da06d697b167f353f115b8e is the toplevel transaction ID: www.blockchain.com/btc/tx/78f0e6de0ce007f4dd4a09085e649d7e354f70bc7da06d697b167f353f115b8e See Section "Nelson-Mandela.jpg" for a detailed reverse engineering of the format, and Section "AtomSea & EMBII data format" for a summary of it.
The system shows the messages and the images on a single page: bitfossil.org/4cbb32cd27b5b5edc12d3559bdffc1355ac2a210463d5cfaadc7ce9b06675b2b/index.htm It is basically a blockchain-based Twitter.
