NO, because something terrible could happen like being mistaken for a Triathlete🤣. But seriously, Yeah why not? Not gonna rush out and buy one though, I like the flexibility of separate kit.
What happened to going over other disadvanteges? Can you explore subject further in show/tech clinic? How does comfort, loo stops, general durability, changing, garment care, temperature ranges, price, color options, reactions, modesty, versatility all compare?
going to the toilet isn’t really an issue, as it zips down the front. Price wise, it’s cheaper than a separate jersey and shorts. Comfort wise, i really like it.
I've already discovered that a speed suit is definitely the most comfortable choice in cycling kit. Unexpected benefit - the pockets are always in the right place! I often end up with something heavier in one side pocket than the other and with a usual jersey that will pull the garment around as the miles go on. Meanwhile my Doppio suit (Giordana's term) keeps the pockets right where they should be.
I've noticed for years that when coasting downhill I quickly accelerate past other riders. I'm 5'9" and 190 lbs (175 cm, 86 kg) with spindly limbs and a substantial beer belly. I have long wondered if I was somehow more aerodynamic due to my rounder shape. I have a plan to test this. If you lot would do consecutive runs wearing a false baby bump, we could test my hypothesis. If speedier, it might even be race legal. Of course, after viewing this vid, I'm leaning towards the extra tight fit of my jersey and shorts.
That has been confirmed by wind tunnel testing (see e.g. Swiss side) and there is a GCN video about it: ruclips.net/video/Z4Te-wrCQsM/видео.html - banned by UCI though if artificial 🤣
Are these other riders of a similar weight to you or lighter? The physics of descending are that heavier riders win out because there is more gravitational force but drag is fairly similar.
I'd wear a speedsuit for a race anytime (as I already do anyway), aside of being more aero I like just the feeling of it staying in place in cyclocross, where your standard jersey usually goes up a bit in a run or something. But for general riding I'm still in the shorts + jersey camp for a simple reason: taking a wee. You don't have to unzip anything to do that, which I think pretty much equals the time difference and I don't have to feel wierd half undressing myself on the side of the road.
Geeee I can strongly relate to the latter feeling... as I remember once wearing my entry-level speedsuit (VAN RYSEL, sold for €45 by Décathlon stores) whilst cycling across Versailles on a dazzling summer day. Suddenly had an urgent need to relieve myself (#coffeejunkie. Ended up half undressing in a sparse, thorny hedge right behind the Château... with throngs of tourists walking by within earshot!!! I've never worn it since.😅😅
@@Cycling_Wandererhigher quality speedsuits have a slit under the zipper, if you look up the gobik skinsuits or castelli speedsuits they all have that and fit amazing (better than bibs+jersey) and look better. Buy pretty tight. Castelli has smaller sizes than gobik, I personally love both but gobik looks better (have modern designs) and feels better quality wise. I now own 5 skinsuits and don’t plan on going back to jerseys+bibs. It’s often cheaper too! I know what suit you have, I tried one myself at the decathlon store but didn’t end up buying it since I didn’t like the fit and quality plus it’s actually a tri suit. Make sure to buy a cycling speedsuit and not a tri suit, since castelli sells both. Good luck and have fun riding!

Interesting results but I wouldn't wear one as I'd look (or at least feel like I looked) ridiculous at my age. Plus I like the ability to swap out tops and shorts as required. And I expect they are very expensive
I'm not sure it's more expensive than a good bibshort+Jersey. I remember I bought a one piece combi for 170€ (A Rapha combi on sale), if you compare with the equivalent short and Jersey, it's probably less expensive...
For racing, a skinsuit is an easy gain. On the road, for general riding...sometimes I wear one. I find a skinsuit to be more comfortable, but I do tend to reserve it for faster rides which aren't too long (less than 50 miles), as the pockets are generally a bit small for additional fuelling and they are trickier for loo stops.
I often wear a speed suit (or Flyte suit as Pactimo calls it) and find it be surprisingly comfortable and still practical. Fits better than well fitting aero jersey/shorts combo. It's my default kit for racing and still a viable option on 200+km rides. Still have aero jerseys and bib shorts but those are more for daily use or training. I did crash and rip the one-piece but I was able to DIY repair it with some iron-on neoprene patches. My $0.02...
A racing suit is one of the few items that is more aerodynamic and lighter. Aero - wheels or frames are heavier, which eats away some of the aero advantage. For 30 years I have been riding a route through the Odenwald in Germany at least once a year with 93 km and approx. 930 meters in altitude. I was able to achieve my best time at the age of 40. At the age of 50, with the Castelli San Remo 2 racing suit and an average speed of over 30 km/h without a slipstream, I was almost as fast as when I was 40, despite a little weight gain.
I do triathlon, I almost never wear a tri-suit (closest thing I have to one of these) outside of a race. For training rides and just general cycling I'm quite happy being slightly less efficient and slightly more comfy.
I only wear trisuits for both running and cycling since I don't like the "pampers" in the cycling shorts. ( my saddle also doesn't have padding otherwise I feel like I have a flat tyre )
At 68 with just a bit of a potbelly, I think I better take a pass! I won't wear a speedo either. But you boys go right ahead. Although, I do think you should have asked Manon to give you guys a thumbs up or down on your wearing speed suits. It is always important to keep the ladies view on guys in lycra in mind.
Could you do a testing between normal road cycling helmet vs aero ones. Those with minimal air vents. Would be interesting to know the watts saved if any.
Wow this was a good lowkey ad. Might look into the Castelli BTW Speedsuit now. Issue is that I have no idea what size to get nor any places that have them to try on.
I think in the UK you would wear a 1 piece about 2 or 3 days a year. It is normally too cold to not wear a base layer or jacket, even in spring/summer.
Great video, those results are surprisingly large. I would like to offer a counterargument to Ollie's claim that Castelli introduced this as a tool. I was wearing a "speed suit" in the early 90s, but I admit that I never wore it in a crit for fear of being laughed at and not knowing how much aero mattered; I only wore it for my TTs and training for the TTs. It was all super tight lycra shorts and jerseys using the same material throughout, in two colors. What I have seen change in the last decade or so, and maybe what Ollie was pointing out, is that Castelli and now others have added more "engineering" backed by wind tunnel testing into their garments beyond just making them a tight fit. The new speed suits often use 3, 4 or more fabric types on one suit depending on the location (shoulders, chest, back, shorts, etc) and are engineering "textures" to achieve the effect they want for that part of the body. I now have a modern suit and love the front "screen door" flaps at the front that allows you to open it up on a climb and make it easier to pee than the single zipper down the middle that always stopped to short.
There is a difference between a speed suit (other brands have various other names) and a TT skinsuit. The speed suits really are like stitching together shorts and jersey. They are separate pieces of fabric that are only joined together from the point of your hips back. So when unzipped, the front is able to open like a jersey, whereas in the TT skinsuit the zipper stays together at the bottom.
I'm not sure a skin suit would offer me the same level of belly support that the two layers from bib shorts and a jersey does! Maybe when I'm back at my summer weight!
I started about a year and a half ago wearing the aero suit on rides where I wanted a bit more speed and I like them when the heat ramps up here in Arizona. The one piece Santini Kit are cooler, which again helps with speed.
I’m not surprised by the difference. I’ve always opted to use speed suits during chain gangs and crits. I’ve got about 4 in total, 2 for TT and 2 for Crits. Inevitably, speed suits are great if you’re targeting speed, but I’d never be comfortable wearing them out on a club ride. 😅
Nice video guys! For the average amateur cyclist, it might not be the best choice price and usage wise. But if you compete often, then, absolutely! Thanks for the insights :)
For me personally, I prefer wearing the aero skinsuit. Not for the aerodynamic advantages but I was very fortunate to get a 3D fitting with Nopinz a few years ago and it means I can literally have a perfect fitting kit which is amazing as I have a long torso and short legs so it's a pain in the arse getting kit that fits
@@gcntech I feel very fortunate to be able to have the opportunity to wear it to be honest with you I am faster yes with less power output which is a nice feeling, fitness wise I'm not sure but I actually don't get sores behind my knees anymore as my bib shorts would rub there
I’m 100% with Ollie. I think the aero suits look so much better. Not only are they just more sleek, but you often end up with longer jerseys tailing over the bum or sagging off to one side (especially when you’ve got pockets full of things). It’s something you see in fondo’s all the time. That, or sweat patches around the waist on hot days, but generally, I think folks need to remember that in terms of how different they look… to non-cyclists they think we look ridiculous anyway. Who are we trying to kid that we look ‘better’ in a separate jersey and shorts? It’s all pretty ludicrous. I’m waiting on my NoPinz kit to arrive in a few weeks. Can’t wait to go an attack my favourite segments to see what difference it helps me to make.
I own two road speed suits with pockets. One is NoPinz and I love it. I probably wear it the most out of my other kits. Don't really care about the aero, just like the look.
@@gcntech Going fast is what I find fun. I don't care how I look if there is a way to go faster. Goodness knows what I look like in my garage on Zwift! I'm usually a mess! No shades to hide behind, no helmet to mask the sweaty head, no cool jersey design to cover what is usually hidden on the road. embrace it all. Cycling is fun.
honestly as an amateur got a suit just to see what they are like. really comfortable since you dont have bib straps, honestly if companies could make a version that sort of looks more like a jersey/short combo rather than a form fit, i could see people moving to that due to the comfort gain maybe change the name from skinsuit or speedsuit to something like one piece or combo to make it sound less weird to new people?
There are companies that have these, you just have to pick the right model. Road versions are the most common ones, that you are looking for, but they also have variations of even those. I've seen road, mountain bike, time trial, cyclocross, and triathlon just to name a few.
I have been wearing a one piece suit for years now - frankly I don't see the downside - it fits better, it is more comfortable and is faster. For anyone worried about looks - you will look like a speed machine and nobody will see you anyway - you will be just a blur! But seriously - I personally like the looks and that is all I need. This video reminded me I tore one of my suits to shreds in a fall last year - just ordered the model Alex was wearing - thanks!
I agree. I dont understand these ppl who care about their looks. Cycling isnt a fashion show. Im all in for performance and comfort gains. People in reality dont care what you wear within reason.
I like to mix and match jerseys and shorts/tights depending on the weather so its separates for me. Plus which speed is not my primary reason for riding.
Been using them since I've first got into the sport about 8 years ago. Both practical and comfortable in my opinion. People forget or ignore the fact that a majority of the drag on the bike is the rider, so it makes sense to reduce the drag as much as possible vs purely focusing on the bike. As far as looks go, since there's a lot of self conscious people on here reading through the comments, it's never bothered me one bit. I think it looks way better than your standard jersey and bibs.
Yep. Every ride. Even just the comfort factor, without those extra straps. A lot cooler too (Australia as it's only one layer on my back and waist. And some brands are coloured and made so it doesn't look like you're wearing a one piece. I haven't worn separates for years
I noticed you didn’t wear arm warmers with the skin suit but you did with the regular riding kit which is a big aero difference (hairy arms = drag) and probably why your time difference isn’t as big as Alex’s. If I was racing I’d use one but at this point of my cycling life I’d rather be comfortable 😊
Really clear stats. My question as an ex pro clarinetist, who can see how well top amateur clarinet players are doing is: how much time and training would Alex need to do to reverse the rise of a hugely and rightly applauded Ollie (as a beacon to us all) to re-assert Alex's superiority as a pro. I don't play the clarinet AT ALL anymore for a number of reasons, but would guess that a month's serious practice would see me back in the groove. What would it take for Si, or Alex (sorry Dan), to regain the podium place over Ollie? No desire to do Ollie down - his improvement has been a huge inspiration. By the way, I won't be wearing a one piece any time soon as I'm overweight and that is clear enough in shorts and jersey.
I don't think that I would, I would love the potential 1 minute improvement.. but first, I need to loose a bunch of weight to be aero... as a person... and honestly, I enjoy the variety of jerseys which I ride in now, I would miss changing it up, too much invested to switch now. I am assuming that the cost will be significant as well, at this point in my cycling career, I'll try the socks first
Used these now for over 5 years, not to make me any faster but simply for comfort, the lack of straps just makes these more breathable on the occasional hot day we have.
While I'm not a fan of, and think there are significant flaws with, the type of "testing" where you ride to a set power, this did finally produce some usable results. When you compare the "gains" from this test to the gains from your recent aero v lightweight bike test it reminds us that 80% of a rider's CDA comes from their body and not their bike. You can micromanage the '20%' with thousands of dollars/pounds in equipment to gain 25 seconds, or you can buy an aero suit and get a bike fit for a fraction of that, and gain a minute or even a minute and a half.
A onesie for training and competition, and a bib with jersey for those leisurely rides. The onesie wins the comfort department, due to no straps. Not that some companies don't develop very comfortable bibs, so not all straps are uncomfortable. Aero suits come in a variety as well, with some being a tad restrictive when standing.
I like the variability of a separate jersey. I have a couple of pairs of shorts that im super happy with and just switch out my jerseys. Don’t want to keep having to buy a all in one when i want a change.
Interesting video - I’ve just got myself an aero suit, so I’m curious to see the difference. Different point - what happened to repetitions to ensure better quality empirical data? Oli would surely agree that at least 3 repeats of each run should get better data than 1 run. Thanks!
I LOVE my speedsuits, got several ones from both Castelli and Bioracer (TT nut) and I love the fit and the look. For everyone saying they would look ridiculous: they slightly correct your body (my 80kg 1.8m torso looks amazing in them). If I could afford it I would wear them all the time. It's not that they are expensive, a decent suit is about the same price as a good shirt and bibshort combo, but in my case my bibs wear out sooner than my shirts, so when I fully switch to suits I'd be replacing my gear more often. So for now I only wear them on my TT bike, both racing and training, and switch to regular gear on my roadbikes.
@@jackal6234 Probably the smallest, but you should check their sizing charts to be sure. They size on hip, chest and waist and not length or weight so that makes it a little harder.
@@jackal6234 Santini has italian sizing which indeed is better for skinny riders. I'm pretty big, 6 feet and 80kgs and my Bioracer speedsuit is 'european sizing' and size M, I also have a Castelli speedsuit (also italian sizing) which is size L.
@@sjurk81 Wait so. The italian sizing which is meant good for skinny riders and thr European sizing is different right? ES is kinda like for buff kinda cyclist compared to Skinny?
Even if there were no aero benefits I’d prefer wearing the one-piece suit. I find them more comfortable and better fitting than individual shorts and jersey, largely due to the lack of bib straps. I was an early adopter of the suit, trying the Castelli San Remo suit shortly after it’s initial release. For me, it was a similar difference in comfort over traditional bibs as those bibs were to standard shorts.
I only where my skinsuit for rides where I am trying to PB something (time for a distance for example) outdoor training I use brands endurance or training kit And for faster social rides I tend to go with aero kit
I love that uneven pocket load won't shift the suit around as much as a jersey would. Inline speedskaters have been wearing those for two decades at least, watch some videos of Berlin marathon for example.
I’m not a bit surprised by these results I have a couple of very close fitting jerseys, one of them with long sleeves. If I feel like having a fast, (well fast by my standards) blast I will use one of them. If on the other hand I wear my club jersey, it’s a bit like riding in a tent!
Nice location at Tossa de Mar and a beautiful coastal road….brings back great memories of my Girona trip last year. Anyway about the video I still wouldn’t wear a speed suit on all rides….I do when racing. Why? - More expensive - Less versatile. I.e. chop and change tops and shorts - Less practical when needing the loo. - Typically no pockets/small pockets. - Can’t use them as a layer in winter - Look like an idiot in the cafe - Just not accepted out of racing. I.e. get a life if you feel you need it on a group/social ride. Also I am a bit skeptical of the results when sponsored by Castelli, was your position consistent? Also the biggest variation in results was Alex at a lower power and his weight presumably going a lot slower….yet a bigger difference.
Hello! Compare road bike aerodynamics for 2 positions. 1. The cyclist keeps his forearms on the handlebars (forbidden by the UCI in group racing). 2. The cyclist holds the handlebars by the lower levers (80s classic).
I'd wear one; it looks a little less serious and more practical than a skinsuit thanks to the pockets with presumably most of the benefits. BTW with the Castelli BTW (ha), what was the sizing like compared to normal Castelli? Would you size up or just go with normal castelli sizing?
@@DerekWhiteRidesABike Is the sizing between the SanRemo and BTW the same? Some skinsuits are tighter than others; with the BTW being their "ultimate" speedsuit I was thinking maybe it's extra-snug.
20 years ago maybe, but now I am too old to wear aero. After the transition from a 6pack to a rice bag, it will annoy the people around me. After I turned 50, fun on a bike is more important than speed.
Fundamentally one-piece suits are great. I grew up in them as an jnkine speedskater. But they are a faff as well. Getting them on a off is more difficult, and you can't go full Schleck in them, which is a knock against them
The sleeveless onesie thing I have was marketed as a triathlon suit (possible translation error), which is probably why it doesn’t contain any pockets. I mean the delusion of speed is great but going to the toilet is an issue…it’s like rounding you back and rotating your pelvis forward/upward enough in the hope that the stitches don’t break! Anyhow, feeling fast is fast!!
An aero onsie might be just what I need to get the KOM on my local Strava segment... Would it save me 2:12 on a 4km, fairly flat piece of road compared to my normal cotton t-shirt and sweatpants? 😁
It's as simple as this. A sweat alot. If you think Si was bad, you've seen nothing! So the first bike type kit was of all things a trisuit, simply because they are designed for swimming, and it would be wet, (and the extra padding was an issue with cycling kit)...not from swimming. Not a fan of the transparent parts as seems to be the fashion with any cycling kit. My theory is however, is that when I'm riding, I'll be fast enough no one will recognise me, and other cyclists around my speed don't care! I do have some normal kit now, but I prefer the comfort of the trisuit, and now cycling specific one's with more padding, now that I've found a very narrow saddle that works for me.
I would race in one for certain by your simple test the aero gains are just to big to ignore , wasn't the first venge aero from supposedly 40 faster over 40 km and that was at pro level speed s of 48 km/ h +
I really like riding in a skinsuit. It's comfortable and my jersey doesn't slide up anymore. When I mentioned it to my cycling buddy he asked what would I do if I needed to poop and I never want to find out 😂
Tech is amazing and no doubt I would wear the areo suit, but I still think I'll benefit more from losing 10kg ;) The socks though.... I am going full Dan Bigham on my sock game this year!
So this sounds like an add for Castelli. Guessing Ollie went about 1 meter per second faster or 48 to 50 meters per half hour, with the same power over the course with the faster kit. How much does the faster kit cost per meter per second compared to the bib and jersey? What is the replacement cost when crashed, which almost everyone will do at some point, compared to replacing your onesie compared to just a jersey or just bib short?
The one-piece is like any other kit, you may like it better if the color scheme is awesome. For me, I have bibs and a top. Maybe I can "upgrade" later.
Given my rides are mostly to and from the cafe or donut shop while I definitely would like to get there quicker likely the one piece isn’t in my future
I'm already in the process of converting over to using skinsuits almost entirely. That big of a time difference must be - what - 20 watts? At least 10, right?
#AskGCNTech: I have already thought about buying one, especially when I bought aero sleeves and -socks from rule28 last year, and I could at least on one run exceed 58.6mph on a descent. There is only one thing, I need jerseys in XS, and bibs in M, can any one-piece suit combine both (eg by more strechable material)?

Not on public road but here will get you an idea ruclips.net/video/hd0fXhDkH84/видео.html I am sure this GCN video help
Wow this was a good lowkey ad.
Might look into the Castelli BTW Speedsuit now. Issue is that I have no idea what size to get nor any places that have them to try on.
I think in the UK you would wear a 1 piece about 2 or 3 days a year. It is normally too cold to not wear a base layer or jacket, even in spring/summer.
Great video, those results are surprisingly large. I would like to offer a counterargument to Ollie's claim that Castelli introduced this as a tool. I was wearing a "speed suit" in the early 90s, but I admit that I never wore it in a crit for fear of being laughed at and not knowing how much aero mattered; I only wore it for my TTs and training for the TTs. It was all super tight lycra shorts and jerseys using the same material throughout, in two colors. What I have seen change in the last decade or so, and maybe what Ollie was pointing out, is that Castelli and now others have added more "engineering" backed by wind tunnel testing into their garments beyond just making them a tight fit. The new speed suits often use 3, 4 or more fabric types on one suit depending on the location (shoulders, chest, back, shorts, etc) and are engineering "textures" to achieve the effect they want for that part of the body. I now have a modern suit and love the front "screen door" flaps at the front that allows you to open it up on a climb and make it easier to pee than the single zipper down the middle that always stopped to short.
There is a difference between a speed suit (other brands have various other names) and a TT skinsuit. The speed suits really are like stitching together shorts and jersey. They are separate pieces of fabric that are only joined together from the point of your hips back. So when unzipped, the front is able to open like a jersey, whereas in the TT skinsuit the zipper stays together at the bottom.
I'm not sure a skin suit would offer me the same level of belly support that the two layers from bib shorts and a jersey does! Maybe when I'm back at my summer weight!
Can relate
There is something to be said for the style of bibs and jersey 👀
I started about a year and a half ago wearing the aero suit on rides where I wanted a bit more speed and I like them when the heat ramps up here in Arizona. The one piece Santini Kit are cooler, which again helps with speed.
Would you consider jumping from your jersey and bibs to an aero suit? 👀
I’m not surprised by the difference. I’ve always opted to use speed suits during chain gangs and crits. I’ve got about 4 in total, 2 for TT and 2 for Crits. Inevitably, speed suits are great if you’re targeting speed, but I’d never be comfortable wearing them out on a club ride. 😅
Yep, they certainly have their place, but a club ride may not be that!
Nice video guys! For the average amateur cyclist, it might not be the best choice price and usage wise. But if you compete often, then, absolutely!
Thanks for the insights :)
For me personally, I prefer wearing the aero skinsuit. Not for the aerodynamic advantages but I was very fortunate to get a 3D fitting with Nopinz a few years ago and it means I can literally have a perfect fitting kit which is amazing as I have a long torso and short legs so it's a pain in the arse getting kit that fits
That's amazing! Custom kit can be a game changer, so cool to hear you've had a good experience. Has it helped your riding and fitness? 👀
@@gcntech I feel very fortunate to be able to have the opportunity to wear it to be honest with you
I am faster yes with less power output which is a nice feeling, fitness wise I'm not sure but I actually don't get sores behind my knees anymore as my bib shorts would rub there
I’m definitely getting the btw suit for this summer.
I’m wearing a cycling speed suit since 10 years!
I was an inline skating competitor and I always wondered why nobody use those for cycling.
I’m 100% with Ollie. I think the aero suits look so much better.
Not only are they just more sleek, but you often end up with longer jerseys tailing over the bum or sagging off to one side (especially when you’ve got pockets full of things). It’s something you see in fondo’s all the time. That, or sweat patches around the waist on hot days, but generally, I think folks need to remember that in terms of how different they look… to non-cyclists they think we look ridiculous anyway. Who are we trying to kid that we look ‘better’ in a separate jersey and shorts? It’s all pretty ludicrous.
I’m waiting on my NoPinz kit to arrive in a few weeks. Can’t wait to go an attack my favourite segments to see what difference it helps me to make.
I own two road speed suits with pockets. One is NoPinz and I love it. I probably wear it the most out of my other kits. Don't really care about the aero, just like the look.
Looking ridiculous is all part of the fun, right? 😂
Getting them off after being sweaty on your own is a real PITA. Those with short sleeves are worse.
@@gcntech Going fast is what I find fun. I don't care how I look if there is a way to go faster. Goodness knows what I look like in my garage on Zwift! I'm usually a mess! No shades to hide behind, no helmet to mask the sweaty head, no cool jersey design to cover what is usually hidden on the road. embrace it all. Cycling is fun.
@@chuckprocner8410 Need a skin suit removal team :D
honestly as an amateur got a suit just to see what they are like. really comfortable since you dont have bib straps, honestly if companies could make a version that sort of looks more like a jersey/short combo rather than a form fit, i could see people moving to that due to the comfort gain maybe change the name from skinsuit or speedsuit to something like one piece or combo to make it sound less weird to new people?
There are companies that have these, you just have to pick the right model. Road versions are the most common ones, that you are looking for, but they also have variations of even those. I've seen road, mountain bike, time trial, cyclocross, and triathlon just to name a few.
Looking great Alex, what shoes and shades are you sporting?
Wore a Nopinz skinsuit for a few TTs as well as DHB Aeron shorts and jersey and never noticed such a massive difference (at about 270 watts).
I have been wearing a one piece suit for years now - frankly I don't see the downside - it fits better, it is more comfortable and is faster. For anyone worried about looks - you will look like a speed machine and nobody will see you anyway - you will be just a blur! But seriously - I personally like the looks and that is all I need. This video reminded me I tore one of my suits to shreds in a fall last year - just ordered the model Alex was wearing - thanks!
I agree. I dont understand these ppl who care about their looks. Cycling isnt a fashion show. Im all in for performance and comfort gains. People in reality dont care what you wear within reason.
@@saunadude8082 You’re so wrong. It’s a total fashion show where the premium brands are what people aspire to. Like other walks of life
I like to mix and match jerseys and shorts/tights depending on the weather so its separates for me. Plus which speed is not my primary reason for riding.
Been using them since I've first got into the sport about 8 years ago. Both practical and comfortable in my opinion. People forget or ignore the fact that a majority of the drag on the bike is the rider, so it makes sense to reduce the drag as much as possible vs purely focusing on the bike. As far as looks go, since there's a lot of self conscious people on here reading through the comments, it's never bothered me one bit. I think it looks way better than your standard jersey and bibs.
Yep. Every ride. Even just the comfort factor, without those extra straps. A lot cooler too (Australia as it's only one layer on my back and waist. And some brands are coloured and made so it doesn't look like you're wearing a one piece. I haven't worn separates for years
I noticed you didn’t wear arm warmers with the skin suit but you did with the regular riding kit which is a big aero difference (hairy arms = drag) and probably why your time difference isn’t as big as Alex’s. If I was racing I’d use one but at this point of my cycling life I’d rather be comfortable 😊
Think they are supposed to be more comfortable I believe
Really clear stats. My question as an ex pro clarinetist, who can see how well top amateur clarinet players are doing is: how much time and training would Alex need to do to reverse the rise of a hugely and rightly applauded Ollie (as a beacon to us all) to re-assert Alex's superiority as a pro. I don't play the clarinet AT ALL anymore for a number of reasons, but would guess that a month's serious practice would see me back in the groove. What would it take for Si, or Alex (sorry Dan), to regain the podium place over Ollie? No desire to do Ollie down - his improvement has been a huge inspiration. By the way, I won't be wearing a one piece any time soon as I'm overweight and that is clear enough in shorts and jersey.
I don't think that I would, I would love the potential 1 minute improvement.. but first, I need to loose a bunch of weight to be aero... as a person... and honestly, I enjoy the variety of jerseys which I ride in now, I would miss changing it up, too much invested to switch now. I am assuming that the cost will be significant as well, at this point in my cycling career, I'll try the socks first
@GCN - You should do a video on just the socks? How much time do they save on a 15kM time trial?
Used these now for over 5 years, not to make me any faster but simply for comfort, the lack of straps just makes these more breathable on the occasional hot day we have.
While I'm not a fan of, and think there are significant flaws with, the type of "testing" where you ride to a set power, this did finally produce some usable results. When you compare the "gains" from this test to the gains from your recent aero v lightweight bike test it reminds us that 80% of a rider's CDA comes from their body and not their bike. You can micromanage the '20%' with thousands of dollars/pounds in equipment to gain 25 seconds, or you can buy an aero suit and get a bike fit for a fraction of that, and gain a minute or even a minute and a half.
A onesie for training and competition, and a bib with jersey for those leisurely rides. The onesie wins the comfort department, due to no straps. Not that some companies don't develop very comfortable bibs, so not all straps are uncomfortable. Aero suits come in a variety as well, with some being a tad restrictive when standing.
I like the variability of a separate jersey. I have a couple of pairs of shorts that im super happy with and just switch out my jerseys. Don’t want to keep having to buy a all in one when i want a change.
Interesting video - I’ve just got myself an aero suit, so I’m curious to see the difference. Different point - what happened to repetitions to ensure better quality empirical data? Oli would surely agree that at least 3 repeats of each run should get better data than 1 run. Thanks!
Three repeats-randomized run order, etc.
I'd have a go! Might need one for each leg though.
I LOVE my speedsuits, got several ones from both Castelli and Bioracer (TT nut) and I love the fit and the look. For everyone saying they would look ridiculous: they slightly correct your body (my 80kg 1.8m torso looks amazing in them).
If I could afford it I would wear them all the time. It's not that they are expensive, a decent suit is about the same price as a good shirt and bibshort combo, but in my case my bibs wear out sooner than my shirts, so when I fully switch to suits I'd be replacing my gear more often. So for now I only wear them on my TT bike, both racing and training, and switch to regular gear on my roadbikes.
I am about to buy the Bioracer RR Suit. What is their sizing? Im very skinny person. 5'11 height and just 50kg. Very low muscle mass. Whatchu think
@@jackal6234 Probably the smallest, but you should check their sizing charts to be sure. They size on hip, chest and waist and not length or weight so that makes it a little harder.
@@sjurk81 how about the Santini. A lot of ppl says that their jersey runs small so skinny riders are good to go and get the Santini?
@@jackal6234 Santini has italian sizing which indeed is better for skinny riders.
I'm pretty big, 6 feet and 80kgs and my Bioracer speedsuit is 'european sizing' and size M, I also have a Castelli speedsuit (also italian sizing) which is size L.
@@sjurk81 Wait so. The italian sizing which is meant good for skinny riders and thr European sizing is different right? ES is kinda like for buff kinda cyclist compared to Skinny?
Suite only! It’s much more comfortable as well for me
Even if there were no aero benefits I’d prefer wearing the one-piece suit. I find them more comfortable and better fitting than individual shorts and jersey, largely due to the lack of bib straps.
I was an early adopter of the suit, trying the Castelli San Remo suit shortly after it’s initial release. For me, it was a similar difference in comfort over traditional bibs as those bibs were to standard shorts.
one piece all the way. they look way sleeker and will totally come in fashion in the next 5 years
I only where my skinsuit for rides where I am trying to PB something (time for a distance for example) outdoor training I use brands endurance or training kit
And for faster social rides I tend to go with aero kit
How's the speedy onesy when you need to do a speedy twosy?
I used to wear a one piece only for time trial or crit races. But it’s not a crime if I try it for a road race from A to B 😊
I love that uneven pocket load won't shift the suit around as much as a jersey would. Inline speedskaters have been wearing those for two decades at least, watch some videos of Berlin marathon for example.
I’m not a bit surprised by these results I have a couple of very close fitting jerseys, one of them with long sleeves. If I feel like having a fast, (well fast by my standards) blast I will use one of them. If on the other hand I wear my club jersey, it’s a bit like riding in a tent!
Do you find you end up relaxing more in the club kit? Nothing wrong with taking it slow for a bit! 🙌
Nice location at Tossa de Mar and a beautiful coastal road….brings back great memories of my Girona trip last year.
Anyway about the video I still wouldn’t wear a speed suit on all rides….I do when racing. Why?
- More expensive
- Less versatile. I.e. chop and change tops and shorts
- Less practical when needing the loo.
- Typically no pockets/small pockets.
- Can’t use them as a layer in winter
- Look like an idiot in the cafe
- Just not accepted out of racing. I.e. get a life if you feel you need it on a group/social ride.
Also I am a bit skeptical of the results when sponsored by Castelli, was your position consistent? Also the biggest variation in results was Alex at a lower power and his weight presumably going a lot slower….yet a bigger difference.
I like them and think they look better. But as a female I have encountered some sizing issues, I wear size S bips and M jerseys.
Most companies offer custom tailoring, just need contact them about it.
Hello!
Compare road bike aerodynamics for 2 positions.
1. The cyclist keeps his forearms on the handlebars (forbidden by the UCI in group racing).
2. The cyclist holds the handlebars by the lower levers (80s classic).
Now I want to see Si rechallenge 10 miles in < 20 min on a road bike wearing this!
I have 2 of them from 2 different bike clubs. I've worn them in crits and crit training rides.
I'd wear one; it looks a little less serious and more practical than a skinsuit thanks to the pockets with presumably most of the benefits. BTW with the Castelli BTW (ha), what was the sizing like compared to normal Castelli? Would you size up or just go with normal castelli sizing?
the sizing is the same. I've got both Castelli bibs and a SanRemo skinsuit.
@@DerekWhiteRidesABike Is the sizing between the SanRemo and BTW the same? Some skinsuits are tighter than others; with the BTW being their "ultimate" speedsuit I was thinking maybe it's extra-snug.
20 years ago maybe, but now I am too old to wear aero. After the transition from a 6pack to a rice bag, it will annoy the people around me. After I turned 50, fun on a bike is more important than speed.
I am for white or light grey kits!!! Let's see ya guys!!
in 95' wore a one piece... had my best season - In the US all critics riders and TT events used them....
Was this filmed near Tossa de Mar?
good spot!
@@GCNuser123 cheers buddy 😊 love your presenting work 👍
I like the Sagan glasses
Fundamentally one-piece suits are great. I grew up in them as an jnkine speedskater. But they are a faff as well. Getting them on a off is more difficult, and you can't go full Schleck in them, which is a knock against them
The sleeveless onesie thing I have was marketed as a triathlon suit (possible translation error), which is probably why it doesn’t contain any pockets. I mean the delusion of speed is great but going to the toilet is an issue…it’s like rounding you back and rotating your pelvis forward/upward enough in the hope that the stitches don’t break! Anyhow, feeling fast is fast!!
Cyclists don't ride sleeveless jerseys at all. You literally bought a tri suit my dude.
An aero onsie might be just what I need to get the KOM on my local Strava segment... Would it save me 2:12 on a 4km, fairly flat piece of road compared to my normal cotton t-shirt and sweatpants? 😁
1 minute faster over 9-10 miles with the suit at 175-200 watts? Doing a tri in Sept and will def consider if it will save 5-10 mins overall!
I have my own aero bulge not unlike the Orca Aero. So I should get one of these. ;)
It's as simple as this. A sweat alot. If you think Si was bad, you've seen nothing! So the first bike type kit was of all things a trisuit, simply because they are designed for swimming, and it would be wet, (and the extra padding was an issue with cycling kit)...not from swimming. Not a fan of the transparent parts as seems to be the fashion with any cycling kit. My theory is however, is that when I'm riding, I'll be fast enough no one will recognise me, and other cyclists around my speed don't care! I do have some normal kit now, but I prefer the comfort of the trisuit, and now cycling specific one's with more padding, now that I've found a very narrow saddle that works for me.
I’m in, let’s do it, let’s make the onsis a thing 💪💪💪
Funnily enough I ordered one yesterday 😆
guys can you make some filming videos in Sardinia Italy. I think they had some of the most beautiful roads for a bicycle ride also the food is amazing
I would race in one for certain by your simple test the aero gains are just to big to ignore , wasn't the first venge aero from supposedly 40 faster over 40 km and that was at pro level speed s of 48 km/ h +
They still work with 3 layers over them for the freezing yorkshire weather ????
I really like riding in a skinsuit. It's comfortable and my jersey doesn't slide up anymore. When I mentioned it to my cycling buddy he asked what would I do if I needed to poop and I never want to find out 😂
Tech is amazing and no doubt I would wear the areo suit, but I still think I'll benefit more from losing 10kg ;) The socks though.... I am going full Dan Bigham on my sock game this year!
Haha go for it! Get those gainz
So this sounds like an add for Castelli. Guessing Ollie went about 1 meter per second faster or 48 to 50 meters per half hour, with the same power over the course with the faster kit. How much does the faster kit cost per meter per second compared to the bib and jersey? What is the replacement cost when crashed, which almost everyone will do at some point, compared to replacing your onesie compared to just a jersey or just bib short?
Castelli are our sponsor but they don’t mind if you buy shorts and jersey or a one piece. Btw… the one piece actually costs less!
Well, I'll use my aero-combi a bit more now 😄.
If the loop was 15km then Ollie rode 28.87km/h average standard and 29.63km/h in the suit. That’s really tempting to start using
What are the pads like though?
Do the arm covers make an aero difference?
I always wear a road suit. Most important reason is that it’s more comfortable to me: one layer less and it doesn’t pull my shoulders.
Where were riding? It looked great.
When is part 2 of DIY bike painting coming out?
Yes I do like a colourful caliper.
@@Ed.R damn you autocorrect!!! *shakes fist at the sky in anger*
The one-piece is like any other kit, you may like it better if the color scheme is awesome. For me, I have bibs and a top. Maybe I can "upgrade" later.
Ollie's pajamas are aero. In his sleep he out sprints the sheep and wakes with a satisfying smile of victory 😀👍
I think Ollie's speed kit would have been ever faster with long sleeves.
Given my rides are mostly to and from the cafe or donut shop while I definitely would like to get there quicker likely the one piece isn’t in my future
Even gravel riders have been tested for it... And is real gamechanger
The speed suit is a great way to go for a normal build road rider. I am not a normal build , I wear a XL jersey with a medium short. 6FT 2IN 82 kilo
What a shame, that you missed out on a headsock reference there 1:40
how fast does one need to travel in order to have aero benefit
I'm already in the process of converting over to using skinsuits almost entirely. That big of a time difference must be - what - 20 watts? At least 10, right?
#AskGCNTech: I have already thought about buying one, especially when I bought aero sleeves and -socks from rule28 last year, and I could at least on one run exceed 58.6mph on a descent. There is only one thing, I need jerseys in XS, and bibs in M, can any one-piece suit combine both (eg by more strechable material)?
