2026-02-07: might have lost a the left North Face etip recycled gloves black with white signs, rebuying without too much thinking, redundancy is fine now that I'm old and don't have time: www.amazon.co.uk/dp/B08BDPDNH7
2025-12-28: after losing the Karrimor X Lite Run Black Headband for good going to try a few ones online:
- www.amazon.co.uk/Flintronic-Headbands-Headband-Stretchy-Running/dp/B0D3V4JQHS Chinese generic, 2 for 6 pounds. Band Material Type Cationic fleece.
- www.amazon.co.uk/Columbia-Weather-Headband-Heather-X-Large/dp/B08MQS7NYB Columbia Men's Fast Trek Ii Cold Weather Headband. Size: L/XL, Colour: City Grey Heather
2024-11: OK, I give up, going to try and find the Extremities XDRY again, as these are the perfect gloves for the UK. Buying www.amazon.co.uk/dp/B00OISFUQ4. Their marketing is very confusing and there are several different names for the product, but the label reads "extremities insulated waterpoof sticky power liner glove", black, large. This is the official page: www.terra-nova.co.uk/products/insulated-waterproof-sticky-power-liner-gloves X-Dry Stretch, 100% polyester.
2024-10: going to try Endura Men's Strike Glove - Hi-Viz Yellow, Large www.endurasport.com/strike-glove-hi-viz-yellow/12929542.html | www.wiggle.com/endura-strike-gloves-930526#colcode=93052613. These gloves are high quality, but they are too hot and fleecy for the UK, unless it is an exceptionally cold winter day around 0. This means that they get quite wet from sweat, and they are not that breathable. Also they are very hard to take off and put on, which is painful if you are like me who uses your cell phone for navigation, and while it works with touchscreens, sometimes it's just too annoying and you have to take them off.
2024-05: going to try www.sealskinz.com/products/water-repellent-all-weather-glove Sealskinz Tasburgh Water Repellent All Weather love black large because Extremities XDRY has a hole on right thumb due to gear shifting. This glove is very similar to the Nike academy hyperwam, not really a winter glove feels like. Weird branding...
2023-11: Endura Windchill Bibtights XL - Black: www.endurasport.com/windchill-bibtights-black/12926004.html because knees of dhb one open. I'm an idiot for getting XL... it's just that L felt too short on the top. But ultimately XL was too baggy, this became quite apparent on first usage, L would likely have been better, just would have needed to pull it a bit more. Quality is very good, very water repellent, kept me warm on 2C under very light rain. Also tried www.endurasport.com/xtract-bibtight-black/12926142.html but the sizing was completely different. L on that one as obviously too large, M felt correct.
2023-07: lost my waterproof cap, not cycling specialized, but was useful. Was by itself in crappy backpocket of cheap muddy fox jersey, lots of wind, some fence jumping... Hadn't noted know the brand/model... sad. Let's try Castelli A/C 2 Cycling Cap? www.castelli-cycling.com/US/en/Men/Collection/Hot-Weather-Kit/A-C-2-CYCLING-CAP/p/4523032_008 Single size. Slightly small, but hard to be sure.
2023-07: www.dhbsport.com/products/aeron-short-sleeve-jersey-2-0 dhb Aeron Short Sleeve Jersey 2.0 Colour Ink Blue Size (Standard) L. To prevent crap from falling again hopefully. Felt too small. Material: 100% polyester, inserts, 64% polyester, 6% elastane. Compared to the non 2.0 which I have, the material feels more glossy/slippery. Slightly weird.
2023-05: www.wiggle.com/p/dhb-classic-shorts?color=black&sizeStandard=M dhb Classic Shorts, medium.
2022-05: buying another "dhb Lightweight Mesh Long Sleeve Base Layer", small www.wiggle.com/p/dhb-lightweight-mesh-long-sleeve-base-layer. I notice that it is actually a bit not long enough. Doesn't make a huge difference, but maybe medium or large next time.
2022-12 Rohan Polar Gloves, black, large, 45 pounds. Shell: 85% polyamide, 15% elastane. Insulation: 100% polyester. 100g insulation on back of the hand. www.rohan.co.uk/mens/accessories-polar-gloves Let's see how they perform after hands were very cold on a bike ride with the Extremities XDRY.
2022-08 dhb Aeron Short Finger Gel Gloves 2.0 medium white www.wiggle.co.uk/dhb-aeron-short-finger-gel-gloves-20. For sun/fall protection. In theory should be small according to size guide, but small was over, and I have my doubts it is correct.
2021-12: bought a North Face etip recycled gloves black with white signs, large about 40 dollars: www.thenorthface.co.uk/shop/en-gb/tnf-gb/mens-etip-gloves-4sha?variationId=KY4 let's see how that goes. These ended up being very good. They are not very warm, good for 10-15 C maybe, which is a important range. Water performance is very good
2021-12:
- dhb Windproof Cycling Gloves Small Black 33 dollars to replace the Nike academy hyperwam gloves which I lost a pair of recently. It already had a hole in the thumb anyways from shifting the small gears all the time. S was way too small despite me making hand measurement, returned.
- dhb C1.0 Crossover Helmet Matte Black 58-61cm 40 dollars after recent crash to ensure helmet integrity
2021-06: Castelli UPF 50+ Light Arm Sleeves (Skins) Large White, 29 pounds www.castelli-cycling.com/bg/upf-50-+-light-arm-sleeves/p/451603621P-001. Felt really good. Really does not trap much heat, and completely blocks off sun. It makes you develop a small layer of sweat that keeps you cool, cooler than without the sleeves.
2021-02 Castelli PRO THERMAL SKULLY red www.wiggle.co.uk/castelli-pro-thermal-skully www.castelli-cycling.com/gb/pro-thermal-skully/p/452054220A to help with cold, the X Lite Run Black Headband is just not made for winter.
2021-01: Madison Cycle Everywear Sportive Toe covers. L/XL. www.madison.cc/shop/sportive-thermal-toe-covers/VARCLA121/CLA12104
2021-01: "Endura FS260-NEMO Glove II" Neoprene Winter Handwarmer Large. www.endurasport.com/Gants-Nemo-FS260-Pro-II/p/E1216-Black Let's see how neoprene feels like. Basically it becomes wet with your transpiration, but is still relatively warm, would take it well down to 5C. Likely would work well with heavy rain. Not bad. But does feel a bit cooler than the Extremities XDRY, especially after you walk for a bit, and your hand becomes cold, and it is very hard to warm it because it is also wet.
2020-12-21: "dhb Neoprene Nylon Overshoes" www.wiggle.co.uk/dhb-neoprene-nylon-overshoes large black. After 2 rides, noticed that the front lower part of left foot (the one I put on and off the most) had a hole in it, not sure where it was made. Edit: I later noticed that it is because I have the reflex of braking slightly with my shoes in certain conditions, e.g. at lower speeds in close proximity to pedestrians, the sounds of which also serve as a way to alert them without the need for a loud bell. But it destroys the overshoe, so I have to undo that reflex.
2020-11-06 www.alpinetrek.co.uk/castelli-perfetto-ros-long-sleeve-cycling-jersey/ "Castelli Perfetto RoS Long Sleeve - Cycling jersey" size L Large. On Wiggle: www.wiggle.co.uk/castelli-perfetto-ros-long-sleeve-jersey Feels great. Together with the dhb Merino Long Sleeve Base Layer, I can gown down to 0 Celcius, no problem, and up to 14 with the "Mesh Long Sleeve Base Layer". Breathes great, blocks wind and rain reasonably, and can holds mild rain out on a short 1.5h ride without problem. I used this so much it is unbelievable.
2020-10-17:
- last ride top was a bit cold on shoulders where not covered by arm warmers, about 10C, so going to try: www.wiggle.co.uk/dhb-aeron-rain-defence-polartec-jacket-1 "dhb Aeron All Winter Softshell Jacket", 109.25 pounds, Fluro Yellow, small to match previous tops that worked, approx: 50 polyester, 40 polyamide, 10 elastane, recommended temperature: 2-12 degrees Celcius. Material felt OK, not amazing but OK. Returned because a bit too small.
- the "dhb Classic Thermal Bib Tights" is a bit too warm for lower tens, so going to try "dhb Aeron FLT Roubaix Bib Tight", 85.50 pounds, medium, navy color, recommended temperatures: 6-14 deg C, 84% polyamide, 16% elastane. Hopefully not being marked as "thermal" means it is less warm. Also hopefully being DHB Aeron it will be a bit less baggy behind knees. Returned later because felt indistinguishable from the "dhb Classic Thermal Bib Tights".
For sizing see also: Ciro Santilli's body.
2020-11: Castelli Thermoflex 2 Arm Warmers, Large, 28 pounds: www.wiggle.co.uk/castelli-thermoflex-2-arm-warmers | www.castelli-cycling.com/gb/men/accessories/cycling-leg-and-arm-warmers/p/451953020A-010 advertized 8°-20°C. Was going to buy the DHB ones for 10 pounds less, but always out of so Castelli it is.
2020-08: started getting getting cold, so let's do it:
- www.wiggle.co.uk/dhb-lightweight-mesh-long-sleeve-base-layer "dhb Lightweight Mesh Long Sleeve Base Layer", small, 93% polyester 7% Elastane. Felt a little bit tight on first try, but I think I'll keep it, it might be correct, it's hard to say, and it's not worth my time. If it is too bad I'll just get another one later.
- www.wiggle.co.uk/dhb-classic-thermal-bib-tights "dhb Classic Thermal Bib Tights", medium, 86% polyamide, 14% elastane, 56 pounds. Very slightly tight, but felt right on first try. Some similar URLs www.wiggle.co.uk/dhb-classic-thermal-bib-tights-1 | www.wiggle.co.uk/dhb-thermal-bib-tight
- www.wiggle.co.uk/dhb-extreme-weather-neoprene-overshoe "dhb Extreme Weather Neoprene Overshoe", large, 81% polyamide, 18% polyurethane. Wanted to buy www.wiggle.co.uk/dhb-neoprene-nylon-overshoes which is lighter, but was out of stock. The material felt good, but it did not fit with 2020-04 Giro Rumble VR Off Road Shoe, I should have checked better, maybe it is only for road shoes.Incompatible with 2020-04 Giro Rumble VR Off Road Shoe, so returned it. That shoe is too large.
2020-05 www.wiggle.co.uk/dhb-aeron-short-sleeve-jersey-4/ dhb Aeron Short Sleeve Jersey 100% polyester, Red Large. This one fit OK. Length feels right. When on cycling position, a bit baggy under arms though, but guessing M would be too short? Still already feels less baggy than the cheap muddy fox jersey. Aeron is the second lowest level of DHB top, after the super basic 25 pound one. Material is thin polyester, could be better, but OK.
2020-05 www.wiggle.co.uk/castelli-perfetto-light-2-short-sleeve-jersey/ Castelli Perfetto Light 2 Short Sleeve Jersey 84% Nylon, 16% Lycra. When it arrived, was WAY too small, so returned. Material looked and felt amazing.
2019-12 www.wiggle.co.uk/dhb-merino-long-sleeve-base-layer-1/?sku=5360752872 "dhb Merino Long Sleeve Base Layer", black, small, was right size, wool is a bit itchy, but does feel like it dries off more quickly on long rides than the cheap Muddy Fox polyester cycling Jersey. Pretty warm, too much for 15C.
2019-12 www.wiggle.co.uk/dhb-aeron-winter-weight-merino-sock/?sku=100335580 dhb Aeron Winter Weight Merino Sock, blue, UK 9.5-12. Did not seem to make much of a difference, feet still cold, not wet.
2019-11 Nike academy hyperwarm gloves: www.nike.com/gb/t/hyperwarm-academy-football-gloves-s9Dd8D/GS0373-013 (archive) for 17.99 Pounds from physical retailer. Good intermediate between the Extremities gloves when it gets a bit warmer. 60% polyester/27% nylon/5% rubber/4% elastane.
2019-10 XGC Men's Cycling Shorts/Bike Shorts And Cycling Underwear With High-Density High-Elasticity And Highly Breathable 4D Sponge Padded www.amazon.co.uk/dp/B07BDJP64W (archive). Grey color, red inner butt padding. 2020-08: after using it a lot, noticed that the padding stiches started to come off a bit.
2018 (?) Extremities XDRY gloves Looks like: www.sportsdirect.com/extremities-wp-p/line-glove-91-907293 (archive) Gets wet after a few minutes of medium rain. But does dry quickly. Baggy, multilayer. Says 40 pounds, but always at 20 pound discount, so it is just a marketing trick. On website: Outershell 96% Polyester/4% Lycra (Spandex)Palm 45% Polyester/55% PolyurethaneLining 100% Polyester
2017-09 Trespass Cruzado Male Gloves size S. www.trespass.com/cruzado-unisex-gloves (archive) Markings: crossover gloves. Technical Performance TP75: www.trespass.com/advice/trespass-tp-ratings-guide/ Lost right hand around 2018/2019.
2017 Muddy fox cycling Jersey, orange, polyester, Large, cheap. Works well enough I guess. Could be a bit more tight fitting.
2017 www.amazon.co.uk/Nevica-Unisex-Reversible-Skuff/dp/B07GSD4R7Y Nevica Skuff black
2017 www.ebay.co.uk/itm/254646634761 Karrimor X Lite Run Black Headband. Had a hole in the ear for a long time. Miraculously surived being almost lost on several occasions, including once it fell off from bike and a dude coming behind pointed it to me. But then alas on 2025-12-28 I lost it, noticed next day wasn't there, by chance found it on neighboring park, but it had been torn very badly, a dog must have done that, so I had to throw it away!

Sometimes, these are more than just mechanics, but also have deeper life analogues. The title of Zen and the Art of Motorcycle Maintenance comes to mind. Sometimes they are just mechanics.
With more philosophical metaphors:
- when your bike breaks, that provides an unique opportunity to learn how to fix it: try to fix your own bike before taking it to the shop
- if the wind is blowing against you on the way out, it will likely blow behind you on the way back. But remember that the other way around also applies.
- always take one extra clothing layer than what you think you will need in your back pocket or sport bag, especially when time is changing fast in Sprint and Autumn. The weather on the road outside of town can change very quickly!
- if you took a turn, and it feels wrong, stop to check the map, and possibly backtrack to safety. When it feels wrong, it usually is a bad idea, e.g. roads where cars are too fast/too many. But if you take a wrong turn and it feels right, then follow it without fear and see what it leads to!
- don't carry a speedometer on your bike. Analysis can be done afterwards on Strava. The only measurement that matters is "how awesome am I feeling right now?". Live in the moment instead of checking your speedometer every 10 seconds.
- cycle when you body calls it out of addiction, not out a goal that you've made up that must be reached
With less philosophical metaphors:
- learn how much water and food you need to take for a trip. Otherwise, you will bonk at some time, when you least expect, it happens very suddenly.And then you better hope to God that you can find a food shop nearby. Luckily this was the case for Ciro's first and only bonk so far.And besides bonking all out, being tired and hungry makes you make stupid decision, especially where traffic is involved!Food is safety. Light is safety. Time is safety. Calm is safety. Chocolate bars and candy cannot count as lunch food, only delay lunch. A sandwich with ham cheese and salad is food. A bag of M&M's with a can of soda can bring you back from the dead.When you are not in familiar grounds, take twice as much as you think you might possibly ever need. Hofstadter's law.You will also learn that, surprise surprise, carbohydrates that you ate one or two days before a ride stay stored in your liver and muscles, and also greatly affect how quickly you will bonk, thus the concept of carbohydrate loading.
- correct saddle hight is fundamental, your legs must be almost fully stretched at the bottom position
- it is impossible to reach the correct tire pressure with (cheap?) hand pumps, their only purpose is to fill up a flat tire so you can get home after a long ride. But a track pump.
- clean and lube your chain. The speed benefit is instantaneous and mind blowing. It also greatly improves gear shifting.This also prevents the chain from rusting, because the lube takes up the place where water would stay, and the muck makes it harder for water to evaporate.This is the most common bike maintenance mistake you see on the streets: people with that high pitched overly dry chain noise.
- when a piece on your bike breaks and has no clear name written on it, you can try to identify it Google images
- the more you watch YouTube maintenance videos without haste, the more you end up learn random new stuff that unexpectedly saves you later
- if you took a turn, and it feels wrong, stop to check the map, and possibly backtrack to safety. When it feels wrong, it usually is a bad idea, e.g. roads where cars are too fast/too many
- public place with lots of people are bicycle parking Hell, because due to anonymity and the large number of distractions, it becomes exponentially more likely that someone will fuck you bike somehow, e.g. by dropping it on the ground. Always search a bit for a reasonable place to park, and avoid overcrowded parking spaces at all costs.
- gear change matters
- when you get on your bike to start riding, start riding slowly and gradually switch up pedal forces and gears. Things may have shifted in a weird position as it gets kicked around in parking. Ciro managed to bend his derailleur like that!
- spin to win, AKA learn to user your gears
- it is not shameful to ride on your lower gears on a hill. You can actually go surprisingly fast with them, and conserve energy for later. Learn when to use each gear ratio.
- learn to identify your suppliers:
- www.wiggle.co.uk/: in Europe, this is best place to buy clothing from, and also good for some bike parts. It is the most organized website, and contains non-generic shit which Amazon is full of.For bike parts Amazon is also worth looking into however. Bike parts a bit different from clothing because you have to make sure that stuff fits, so you hopefully know exactly the part name before before buying it, and therefore website organization is not as crucial.Wiggle is however guilty of shameless: discounts that happen more often than not
- always take your lights off the bike into your bag when you park, anywhere, and for any amount of time, even if a quick stop. Drug addicts are everywhere, always ready love to steal and resell them.
- sometimes you do something stupid like going into a really muddy path, and it is really fun, because you've never been there in your life. But then your bike gets really dirty, and your feet are wet and freezing, and you promise yourself you will never do something that stupid again. But then you do it again in a different location, because it was too much fun. Once more unto the breach just comes to Ciro's mind every such time. Embrace this.

- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
