We Legalised The Supertuck! Using A Dropper Seatpost For Aero Gains!

- UPDATE: March 2022. Matej Mohoric has answered this question definitively and the answer is... Watch our highlights of Milano Sanremo 2022 to find out: • Big Names Light It Up ...
The super tuck has been used by pros for years to help them get more aerodynamic, and therefore go faster, when descending. It's actually always been banned by the UCI - but they've recently decided to crack down on pros using this position. Is there an alternative? Can pros use tech to go faster? We think they can! In this video, Oliver fits a dropper post to his bike to see if he can descend as fast as the supertuck!

Do you think the dropper post will be faster than the supertuck?
No, but the Ollie post will do the trick. :)
A dropper with a larger stroke down to the seat post would have most of the benefits of the tuck without the weight imbalance. Win win?
If teams and the industry would adopt this idea, we might be seeing frames that have an inbuilt mechanism for dropping whatever seat post you're using. Then you'd have the same advantage descending and it wouldn't be too heavy going uphill. This is certainly not rocket science, especially with the possibilities that carbon gives an engineer and what is more every type of bike could benefit from this. I often wish for a dropper post on my Giant Revolt Advanced Pro gravel bike but the d-shaped seat tube makes this impossible.
And if it is, how long until dropper posts will be banned for road races by the UCI? 🤔
Once the dropper post is fully integrated into the bike design and can be lowered down to top tube height it should be faster than the super tuck
Ollie telling everyone to *drop* the jokes.
ironic
"Olly Post" 😂 That's a good one!
I want to know who at GCN thought this up? Or is Olli up all night writing a joke book? Whens that going to drop with the publishers?
Why is Olly is under the impression he was the ‘dropper’, and not the ‘dropped’?
@@bobmckenzie394 Well when you drop a seatpost it becomes "dropped"
@@bobmckenzie394 haha oof
@@jackmason2226 it's a pretty obvious joke
Finally ...Today with Matej Mohorič in Milano-Sanremo 2022 demonstrated and confirmed this application ... as he was also inventor of Supertruck position that was banned by UCI ... but you still have to have a good skills of descending the hill even with this technical innovation.
you posted the exactly same comment on a another video.
I bloody love Ollie, he's such a good presenter, always makes me laugh. Please don't ever drop him. From the show that is..
Drop him at will on a ride however.😹
Hahaha you got me
Who came back here after Mohoric won Milan-Sanremo?
best solution for dropper posts regarding the weight of it; Buy an UCI-Illegal bike, give it a dropper post.
Yeah if it's a 6.3 kg bike the dropper post will add the missing 500 grams.
Or if you are smart you would use more aero wheels
Also: there are lighter dropper posts
They will still add 200g or a bit more but 500g is a pretty high estimate I believe.
The lightest dropper weighs about 380g (including cable and remote), most mid-range droppers weigh between 500 and 700g (including cable and remote).
Shorter drop and smaller diameter usually makes them lighter
That moment when you realise that Mohoric watches GCN Tech.
Maybe all the drop jokes is why we seen Ollie on GMBN lately where dropping is something cool. :)
The Pro riders and bike industry will in future be very thankful to Ollie and named it "the Ollie tuck"!
I’m back here to give Ollie the credit for the win and prolly half of Milan Sanremo’s 🏆
Ollie: "If a squirrel was to run out in front of me now I'd be in trouble"
How about the squirrel! 😁
I don't think he's heavy enough to hurt the squirrel honestly
the squirrel would drop him anyway
I’ve run over a squirrel. Broke his neck. Hardly felt it on my end. Hitting a dog can wipe you out but if you see a squirrel don’t cause an accident trying to avoid it
Ask Dan...
Could be hit or miss.
what a nice challenge for the industry. developing a race bike dropper, integrated, aero, lightweight
Yeah well looking at the industry's track record of adopting MTB features does not instill much confidence now does it?
@Andrew Kay I guess your idea is integrating a round tube within the aero profile of an aero seatpost?
The problem with that is that you'd end up with a significantly smaller diameter telescopic tube system which would then require a significant increase in wall thickness and thus weight over the already increased weight of adding an extra tube within the original profile
Once the product comes to market, i won't be surprised if the UCI bans it on the spot
@Andrew Kay you'd think so but the rulebook is als littered with aesthetics-based bans :(
Pedalling would be easier on a dropper post as opposed to the super tuck as well. Possibly an advantage on an undulating descent. It might be interesting to see if this would be a point in favour of the d.p.
If I recall didn't they find that pedaling from a supertuck was slower ... unless you're Chris Froome haha.
Manufacturers (of proprietary seatposts): "wtf! Hey guys..."
UCI: "Hold on Brother, I'm banning."
“The Ollie Post” 🤣 that literally just made my day!!!
Thinking out loud here, but I guess that UCI has defined a bicycle as having only one seat?
That's thinking outside the box!
That will be next on pro hacks and bodges 🤣😂
@@gcntech have just looked at the registration and a saddle there would infringing on how far a saddle is in front of the BB. So it would be a no.
@@darrengarvie8832 Moving the BB to solve that? But, that's probably something the UCI has thought of already.
@@darrengarvie8832 use a tri/Phil Gaimon saddle.
Finally we know what the "illegal" Atheos was designed for
Massive fan of the video, nicely done GCN!
Would you have thought by posting this video that the winner of Milan San Remo 2022, Mr. Mohoric was going to use a dropper seatpost?! You are genius! Keep making videos like these !
Funnily enough, i just ordered my first dropper post for my mountain bike. GCN making a video on it is a surprise, but a welcome one for sure.
And again... Gcn says "Whatever uci, i do what i want!" Awesome video ollie! You rock brother!🤘😝
1.3.008 Position
The rider shall normally assume a sitting position on the bicycle. This position requires that the only points of support are the following: the feet on the pedals, the hands on the handlebars and the seat on the saddle.
(currfent text modified on 01.01.09)
This is fromthe current UCI rules, and as you can see, what has changed is not the rule (updated 2009), but that the UCI says they will be enforcing the existing rule.. what you have missed though, is the lack of the oxford comma after 'handlebars' which thus ties hands to handlebars, and seat on saddle- so no 'no hands' unsless you are standing up, and not using the seat, and with much greater consequence,no standing to climb if you are also touching the handlerbars. Turns out, that the UCI isn't as smart as they think they are.
Fantastic evaluation. Thank you
Well done Olli - really liked this one, especially the critical reflection towards the end.
I really enjoy your videos Ollie! You're my favorite presenter!
You should've tried a longer dropper, 175mm to 200mm for a viable comparison, so as to get into a full tuck, more representative of the "super-tuck".
On a full length dropper post, I think the speed and time results would have been even faster than the "super-tuck" time/speed due to the increased control and confidence one has by having bodyweight low over a planted back wheel and an unweighted front wheel .
Pro teams will have a new variety of dropper post by the time the new UCI rule comes into effect imo. The new dropper will be fully integrated into the downtube, probably made of carbon fibre, much lighter than a MTB dropper. Nice....new, safe, performance tech incoming 🔥🔥
I don't know of a dropper post of those lengths in a 27.2 diameter, but yeah, longer drop makes sense in theory
Think the issue is post diameter. I'm looking at fitting a dropper to my gravel bike, but most of the long travel droppers are geared up for MTB's with a thicker post. my bike only has a 27.2 seat post and I'm really restricted to 100mm or below from what I've seen.
I'm hoping that there are technical advantages that make these more available in the future. something integrated into the frame would be amazing, or a lighter weight carbon post.
@@steveedwards5280 Yes true, good point, thanks Steve. Maximum seems to be 110mm in the 27.2mm range, made by Lyne. I'm sure dropper post companies are very busy in R&D right now, seeing $$$/profits and huge potential in the new Roadie market, once UCI rule comes into effect.
Yup agree need about a 200mm dropper
PNW Components makes the Coast Dropper Post available in a 27.2 diameter post. It also has 40mm of suspension and 100mm of travel. This is good to have when you hit that pothole that you didn't see, particularly if you don't want to look like Hank after his Penny Farthing ride.
Ollie drops post with trigger...and gets trigged by posts about getting dropped
We've already got a number of bikes that fall under the 6.8 Kg limit, for example the Canyon ultimate, I think it's close to 6 kgs if I remember correctly so if you were to remove the seatpost and add a dropper post in there, you should be under the 6.8 limit pretty easily. TBH if this method checks out, canyon or other brands could themselves develop one and change the cycling scene forever. #GCN #GCNTech
P.S. You guys need to do a video on a UCI legal weight bike with a dropper post. :P
new or existing uci rule, " the saddle must be in a fixed position"
That was my thought too. Why would the extra weight of a dropper post be a problem if teams are already having to add weight to their bikes to meet the UCI limit?
@@clydea.hutchisoniv5742 neutral spare bikes already sometimes come with droppers so riders can change the seat height easier though.
@@imperialspy3457 interesting! I never heard of that.
You're god damn right. Matej Mohoric did this and won Milano-Sanremo 2022
Ollie your just brilliant, love watching your videos. 👍
“Dropping in!” Made me laugh. Ollie is my favourite GMBN presenter.
Wow, this is most certainly an interesting video. I hope bike manufacturers are watching! (looking at you Canyon👀)
I would think this is coming to the pro scene after the recent ban. Especially since they are adding weights to make the bikes legal, so its really likely that we'll see dropper posts in the pro peloton sooner rather than later.
proprietary seatposts ? they would have to develope droppers for each seatpost
@@Hugo-um8nh You mean every manufacturer has a new proprietary upgrade to sell? I don't see what they'll object to.
Great video Ollie! That’s a significant result. Maybe some kind of spring loaded hinge system would be possible? The seat would drop a bit forward and all the way down = super aero + great weight distribution👍Allways thinking😅
I really like this presenter. I use their training videos several times a week and I wish this presenter would narrate their workout videos.
I think there should be a recurring segment called “Ollie’s Bum.”
Good idea, thank you for this video! 👍🏻
This is great! Disc brakes already available and next we will hopefully see dropper posts for for road bikes. Next we could add some chunkier knobbly tyres, slacken off the geometry a fair bit, add some reinforcements on the frame and maybe some front and rear suspension too and we will get to a point where road bikes evolve into something that doesn't need to be be used in an environment full of petrol and diesel fumes, pot holes and angry motorists
You should do a video about Pantani's descending style
Been waiting for this!
Meanwhile, Caleb Ewan sprints very safely with his nose rubbing on his front tyre.
Good point!
Most sprinters for that matter.
Actually no, he doesn't sprint like that very often because it is so damn sketchy.
I can see teams like UAE, Jumbo Visma and Ineos working through their integration of the dropper post in top-secret work sessions, holding the trump-card for when it really matters, like a queen-stage of a grand tour.
You will only get the maximum advantage over other riders once, so you need to deploy it strategically. After that first-time deployment, everyone will be fitting one and the advantage will be much diminished.
Ollie - If a squirrel should run in front of me now I'd be in trouble. Me: Try a kangaroo, mate!
more speed to be gained by holding knees together and bringing elbows in tight
Using a dropper post to drop everyone makes the name really fitting
This is done with "non-aero" frame and seat post. Would be interesting to see the same descent on your Pinarello in the normal position to see if frame aero is more important than a supertuck.
*Well the bike manufacturers can make a frame 500grams lighter to offset the weight gain from the dropper post.*
Because the seat tube is angled, the dropper post will push the seat forward as it drops. Ideally you would want the seat to go slightly backward for better balance and control. Not possible with hack/bodge but doesn't sound a difficult problem for an engineer.
You dropped in a lot of content and I feel like it’s time to drop into my LBS and purchase a dropper post. In hoping the price has dropped a bit as well. Great review and always entertaining 👍
The rule says you can only maintian contact in three area... butt on saddle feet on pedals hands on bars... (if I am understanding this right this is the same rule that prevents invisible tri bars aka puppy paws). In the B role and a couple of times in the main footage the rider clearly had their chest resting on the stem and or handlebars.... engineer you way around that Dr. Bridgewood! ;)
It would make a lot of sense to fit a dropper post and convert to 1x at the same time, use the left shifter for the dropper, hide all the workings in the frame and offset the weight a bit. The seat needs to go all the way down to the top tube too, no point doing half-a-drop. If it were done properly, it'd be faster still.
I think this may actually become a thing, figure a longer dropper allowing you to get even lower would basically let you be just as fast as a supertuck but much safer. For the high end racing scene I would even expect to see carbon dropper posts, with electronic actuation (maybe sharing the Di2 battery for Shimano users eliminating the weight of an extra battery). I don't think you will see it on all race stages, but for stages with a lot of descending you might see this go on the climbing bikes where the slight aero penalty of the round post is less of a factor, you might even see aero profile droppers in the future.
The supertuck certainly looks dangerous, especially because of the risk of going over the bars when trying to stop suddenly. Weirdly, from a stability standpoint, it seemed like Ollie's descent with the dropper post was the most squirrely - with the front end of the bike darting around a little bit. Perhaps this is due to the fore-aft changes of the center of mass: Much as a large forward distribution of mass in an automobile tends to cause understeer, the forward center of mass of the supertuck seems to be stabilizing from a directional control standpoint. (I understand that that stability gain is offset by weird angle of your arms with respect to the bars, etc. I'm not arguing that it's actually safe.) And just as many rear-engine cars are quite famously directionly twitchy, the dropper post down mode looks like it steers very quickly. If these sorts of dropper post approaches became popular, I wonder if we would see a slight relaxing of the head tube angle or increase in trail to add some high-speed stability and compensate for the rearward weight bias.
4:20 "well, that escalated quickly..."
The Ollie post made a huge difference!
what i happen to do, not so much for more speed, but for more control on steep descends, is a kind of standing position with my bum behind the seat and my belly touching the seat. Now that i think about it, that might give me a small aero advantage too.
Since there's a minimum weight for the bike in UCI races and technically many manufacturers can go way lower than that weight, the addition of weight is not an issue.
If I consider the next Giro d'Italia, the use in Cortina Stage can be interesting.
The entire race is made of big climbs and descents and the last 15KM are in descent.
Maybe the dropper post is an option but the save of drag caused by being behind someone is more consistent than the dropper post option (so I exclude that someone can win thanks to the dropper post).
I don't think that anyone of the bests will use it.
The Drops, Dropper Post and the Dropped! Dr.Ollie is always awesome, nerdy and funny!
I always wondered why riders add dead weight when they could get a dropper post and rail the descents way harder (especially when sharp turns are involved).
Dead weight = disc brakes? xD
excelent video, you could have used a dropper with a longer drop (could always borow one from GMBN) that would get you in the same neighborhood as the supertuck if not even faster due to better control.
Way to 'drop' some science Ollie!!
All the people talking about Mohoric's dropper post, none of them talking about the aero benefits of being suicidal.
Interesting, relevant and well executed.
Brilliant. I expect to see droppers becoming increasingly standard on racebikes, particularly if the UCI doesn't budge from the weight limit.
I remember seeing a dropper post that had a tiny lever just below the nose of the saddle that was used to raise or lower the saddle, I have no idea where I saw it though. Locating the lever there would reduce some of the weight and complexity. Yeah the wireless version with a little blip button would be the way to go though.
The yellow neutral service bikes in the 2019 TDF had droppers.
Considering that a pro's bike has a lower weight limit, and they sometimes have to add weight to keep their climbing bikes above the minimum limit, it seems likely any pro wanting to use a dropper post could easily be able to shed that extra 400g in another area and be able to end up with a bike with a dropper post at the same race weight.
With so many bikes being manufactured below the weight limit already, this just makes absolute sense to use one. Meet the weight, rules, and tuck requirements in a single product! :)
I think that a dropper post could be useful to share a bike between two people with different inseams. My friend borrows my bike sometimes and its not super comfortable for him because the seat isn't where it needs to be in relation to the pedals.
I have been asking why these haven't been used for a couple years now. Especially with the potential for bikes to be well under the UCI weight limit, why not add these?
The CyclingTips podcast discussed this. Essentially that it would add so much weight that it would negate the aero benefits. And that many bikes have non-round seat posts that this wouldn't work with. Notice that Ollie used his Canyon Grail (not a road bike) instead of his Pinarello because the Grail has a round seatpost but the Pinarello does not.
Just finished the whole video. So the same as what Ollie said at the end.
@@alantaylorfarnes With the tech budgets some of these UCI teams have, I find it hard to believe they couldn't get custom posts that still stay around minimum weight.
@@alantaylorfarnes I'm sure the teams could design or buy one with the shape they want so that it would still be aero... And the weight is not an issue, as many bikes are below the UCI limit so they need to add weight to it....
@@BenKickert definetly... A full custom bike and can't make or buy a custom seatpost? Come on
There is an alternate tuck position that is UCI legal and just as fast as the super tuck. i don't understand why more riders have not discovered this and used the position. There are two possible strategies to minimize frontal area. the super tuck minimizes frontal area by getting as low as possible, however because the elbows are beside the torso, the super tuck makes the frontal area wider. The alternative strategy is to get as narrow as possible rather than as low as possible. This is similar to the strategy used to get aero on a time trial bike. Hands will be on the bars and close to the stem. knees together and touching top tube. Elbows narrow and resting on top of knees. Butt on saddle. Based on years of riding big mountain descents with other riders, I find this is every bit as fast as the super tuck. It is safer in my opinion, and much more comfortable and less tiring than the super tuck. I suspect it would be even faster with the dropper post.
If you do my tuck the right way your elbows are tucked in and your knees are touching together behind the head tube.
I feel SAFER in a SuperTuck on a fast descent. I am less likely to be moved laterally by a crosswind (I've experimented with this) and I feel less twitchy at high speeds in general (being lower). I also tell myself, I have less distance to fall to the ground if something went bad 😀
I have my hands in the drops with fingers near the brakes. I have stopped quickly in this position. All works well.
I see some pros descend like how you describe; hands no on the brakes, but instead narrow. Now THAT looks scary as heck and unsafe IMO.
Ollie just wants to change the association of the word drop with his name. A cunning plan indeed.
Just ❤❤ it... A Dropper Post is an absolutely XCELLENT idea. Hope the Tour Teams take this on board guys 2 Stick it Right Up the ICI 👍👌😀
Watching this after Matej Mohoric won Milan-San Remo with a dropper post in 2022.
imho the compatibility is the main issue ... 6.8 kg weight limit should be very much possible with or without the dropper post.
if a rider gets the dropper post with max stroke (in the low position its right on top of the tube) it might equal the super tuck on most descents and maybe even top it on technical sections ...
Many bikes these days are Di2, and store the battery inside the seatpost. With a dropper you need an alternative location to store the battery, which is an issue.
Olly dropping some science with this one
Love a bit of Oli science. For Gravel it's happening and will happen. It was a game changer in MTB. Until weight comes down and aero of course I think we're a little way off yet seeing a UCI legal road version. I would have no problem with it.
Then again, they are already adding weights to bikes, so why not make it have a function.
Ollie, when I descend or 'get arrow' on my standard road bike saddle configuration, I put my chin on the stem, much like you did with the seat dropped down. Did you consider this position with the saddle in the standard position instead of the upright position you held during the test? This may have been more accurate or a 4th option to the experiment.
Since it should be possible to still get close to the weight limit with these I can quite well see them catch on as a feature that is developed to replace the super tuck
I'm still surprised this hasn't caught on. Any time I'm on my MTB and find myself going down a fire road I'll drop my seat and tuck into reduce air drag. I'll usually pass everyone in the group who is pedaling. My gravel bike also has a dropper and I do this for the same effect. It's such a huge benefit!
What about a tuck position where you stretch out and rest your gut on the saddle? Can get a bit lower and put more weight in the back tire which would help if you need to brake
I always wonder when they're making these videos. What about the Aero effect of the camera bike.
This Canyon is such a beauty!
Dropper post is a great solution. Too many bikes these days have custom carbon posts. Round tubes are also no longer on top race bikes. But with only a 2 second difference it is a far superior solution to the super tuck position.
Be great to see the peloton switch to neutral service bikes for the descent in TdF to get the dropper post
I can see pro-team manufacturers incorporating a dropper post in to their next generation standard build, especially for the climbs (as what goes up must come down), as well as looking at handle bar innovations.
Nice looking "OLLIE BAR" on that road bike/gravel bike there🤣😜
Considering how chopped up the air flow must be around the seat post anyway how much would actually be lost going back to a round post? It would solve the problem of questionable engineering solutions for deep section seat post compliance by building some damping in to the dropper mech assuming its not already there.
I'm sure an extendable fin could be arranged for on the trailing side to rejoin lamina flow if it really mattered... I can think of a couple of ways to do it sat here or make specific section posts as mentioned of course. 🤔
I genuinely reckon you boys are on to something though , in fact, it surprises me it hasn't already been done.
Hopefully the UCI doesn't move towards banning the use of the rider position as a moveable aero aid ala F1 or maybe determining only 3 or 4 fixed riding positions as legal
ie, tops, hoods drops and standing up.
If the only argument against the super tuck is safety/control this a definitely a good solution.
Good work!
The vehicle driving beside Ollie to film the descents probably had more influence that his position on his time.
SO I've always wondered if people had a dominant leg position while descending. I'll use the drive-side crank position for crank orientation. Olly switched the crank position depending on if it was the regular seated position (3 o'clock), super tuck (9 o'clock), and the dropper post (3 or 9 o'clock). When I descend my leg is in the 9 o'clock position (no dynamic/moving #BikeVault picture for me 😢) I think GCN should do a pole!
When you descend is your leg predominantly in the:
1) 3 O'Clock position
2) 6 O'Clock position
3) 9 O'Clock position, or
4) 12 O'Clock position
It'd be fun to know 🤷♂️🤷♂️
8:36: That looks like a modified ice-scraper for you makeshift bike stand! 😂
I'm new to cycling & especially racing but come from the similarly wordy rulebook sport of sailing. A few questions on this rule; do the UCI define "normally"? If not, does this now stop riders from getting out of the saddle when climbing? Following that, if you can be out of the saddle, but not supported anywhere else, would it be possible to supertuck without supporting yourself on the top tube?
EXACTLY what I was thinking.
As well as incurring a weight penalty a dropper post would reduce comfort. Much of the compliance in a road bike comes from flex in the exposed seat post, and I bet dropper posts are much stiffer than regular carbon posts.
Especially so in the case of Ollie’s Grail and its flexible VCLS 2.0 post.
Ollie 😂 you're simply the best! LOL
And I thought mine's short... Never thought I'd see such a tiny, short, narrow... Dropper post.
Mtb guy here. You guys do realize you can get 20cm+ droppers right? I'd imagine you'd get down to the toptube with that.
You can, but only with seat post diameters of 30.9 mm minimum. Road bikes are usually 27.2 mm if they’re not aero.
@Finn Bridgham yeah uh. My bike is 15kg, I don't think 100 grams or whatever is worth the dropper being shorter.
@Finn Bridgham But we see that you actually can manufacture bikes that are lighter than 6.8 kg. The weight increase in the dropper post could probably be cancelled out by weight savings in other components.
You could even make some of the "sub 6.8 kg"-bikes UCI-compliant by using such a heavy post.
@Finn Bridgham True (for now). I'm pretty sure aero dropper posts will become a thing if the round ones catch on in road racing. Futhermore: the Specialized Aethos for example fits round posts and weighs about 6kg.
Merci pour les essais A+
As soon as the rule came out, I assumed that manufacturers began developing aero road droppers. I'm sure we'll see them sooner than later. The frame manufacturers will just drop the weight of the rest of the bike to accommodate the extra weight and still hover above the UCI minimum.
That canyon is such a beautiful bike but has a horrible cockpit , those double bars are fugly . but that's just my opinion . And the drop seat post idea is awesome , well done . the weight issue can be picked up by going lighter on other parts of the bike , which I am sure you can do as there's bikes non uci approved cos of underweight . It's just up to the industry to develop a seatpost that fits and drops
