We have been wondering whether it is possible to make our current time trial bikes faster, and more aerodynamic, by adding some home-made make-shift parts to them.
We’ve thrown the rule books out of the window, and it'll raise some eyebrows from the fashion police! No regulations, no constraints, and certainly no consideration for looks.
We’ve seen some bold designs from some brands in recent years, in an attempt to push these aerodynamic advantages. Ours is definitely not going to be anywhere near as technical or sciency, as we have each been given a budget of £20...so let’s see what we can each do!

![ОРБАН приехал к ПУТИНУ и "отчитался" о поездке в Киев 😁 [Пародия]](http://i.ytimg.com/vi/_0ukDovOWq8/mqdefault.jpg)
201W for doing 40km/h. Hell I am not slow then. I am just poor.
Yeah I can hold 260W for close to an hour and my average is only 37.5km/h :(
@@nickr1435 i dont know my power as power meters are expencive
@simon edin Then this video is for you man 👍👍
Pulkit Sharma it’s much more his position than his bike
@@ThemCubesHis bike lets him be in that position. I can't go that aero on my Sora with a slammed stem
You guys are really doing your part to keep us sane and not bored in these times. Keep it going!
Thanks S R, sadly we won't be able to get out for these sort of challenges but will be doing our best in the situations we've got.
Heather and Mark, Thank you for everything you are doing to help keep a smile on our faces at this time. Keep up the great work.
Thanks Donald, this was filmed a while ago but we will continue to do our best.
Last year made my DIY disc wheel with scotch tape and vinyl sticker rolls with carbon look, used for months until autumn winds started, really worked for me, will definitely do it again maybe next month ☢️⚫☣️
GCN already did something like that (try to be aero using cardboard). Maybe you guys could make some hacks (and test later) using 3d printed parts. I know not everyone has a 3d printer at home, but a printer service is relatively easy to find in many cities.
Also, as the channel is always testing things, how about consider using some CdA meter (like Notio Konect)? IMHO these two things will bring very very nice content to GTN.
Great video. Awesome job.
While the test is never gonna be accurate... any thought to starting your Garmin/Wahoo after you're up to speed to remove the acceleration to 40 km/h from your calculations? Maybe Heather just came up to speed much quicker the first run requiring more power for those seconds.
I think the power meter had a dropout, or wasn't even awake at the beginning of the sector.
Been there, done that with my "cheapish" roadbike to good effect. Spent the better part of an afternoon to perfect the esthetics to the point that a few people thought it was a genuine time trial bike.
Great fun, where can I find 'the rule book' ? Interested to discover what is and isn't allowed in Triathlon as opposed to TT (UCI)
Love it. Glad you guys are doing it. Like Mark, not sure I’d want to stick anything on my Trek TT bike!!
I was surprised not to see homemade disc wheel, that’s what I would have done.
Check out Mark's video where he made one that actually works, but does take a little longer than the 30' we had on this occasion.
Heather is so so competitive n smart!! Mark - too much too soon hahaha
Think we both are ;)
defo thinking about a shiny tail for my Giant Contend to get that glamorous edge on the next tt lol
You guys should do this more often like a weekly challenge and do a running series of DIY aero upgrades and race each other with it.
I was also thinking early this afternoon with the cardboard in the frame but the side winds.
Cross wind
Done the same as Mark years ago to my bike, and also added a cardboard front and rear disc wheel. The front disc is really just something for the track or people with a serious death wish. The diamond cardboard triangles and the rear disc I kept on riding for month, till one day the cardbord disc disintegrated during a 60kph descent in the rain. Good times!
Yes that sounds a little scary!
Hey Guys. Are you really in Fuerte at the moment?
I would not expect so at the moment regarding Corona...
Nethertheless the content is always cool.
More of that please.... 😉 👍
Hey Salvatore Santoro, this was shot earlier this before everything came about 🙂
Let's do a competition with GTN!!
From the world of strange devices you could have alternatively created a large single or double splitter plate that started at your helmet and ran down your back. That way you would have attacked the real drag problem in the massive turbulent suction zone area behind the rider back and damped some of the turbulent flow out that makes upright bikes so inefficient.
I reckon if Mark just filled the gaps of the frame in by using tape instead of cardboard it would've been faster and easier to do.
Na it would be the same because tried it myself and it would be just heavier slower because of the cross wind.better to use deepsection frame insted less cross wind issues.
183 watts, pretty impossible power there if this was supposedly a head wind. Conclusion - Power meter dropout.
Just put it in a diy wind tunnel, fair.
Next: diy hacks for swimming
A E R O goggles
Front wheel fairing
by covering the air intakes on the helmet, he's creating more drag by getting more turbulance at the front area haha
I dont think so. the helmets on the track for example the giro aerohead usually dont have air intakes
The venturi effect is something I am not convinced works with a helmet in such chaotic conditions. More like marketing.
How the heck did you get 25 mph from 201 watts?
Is it just me or did Heather put antennas on her helmet??? (@12:41) Ha!! love the vid team!!!
If only they'd stayed on and helped me go faster ;)
Canyon SpeedMark
Having performed real world testing for position optimization, you need a looped course and to do multiple loops at various power levels. Otherwise, the numbers are meaningless because there is too much scatter in the data. Try again guys.
Just wondering why Heathers position is ‘relatively’ unaero?
Elijah, I won't take it personally, but I have done far less TT riding than Mark. My position is a work in progress.
i will send you my hack aerobar upgrade with no money expensive and have best bike aero hack accessories
Heather please keep the same position in the both rounds or its useless
God. 183 watt at 40km/hr
Now that tail thing is what im gonna do in quarantine.
I must admit it was also slightly downhill ;0
GCN did a similar failed test in a wind tunnel so you share lack of aerodynamic knowledge I am afraid. Look up the term virtual airfoil and then forget about about a fully filled framed, because cda is more complex than both channels seem to think. A is pretty similar I think with or without cardboard filling of the side of the frame. The CD increased in the wind tunnel test GCN made due to surface friction of the cardboard vs the virtual airfoil that the frame uncovered is. Think of a boomerang or if you know what an Aerobie ring is for practical examples of virtual airfoil. Both go faaaaar vs a disc like a Frisbee thanks to less air resistance due to the hole(s) in the middle. Heather tested position more than bike part changes and you will see huge benefits tucking in well. There are true gains to be had so please do another video later with a day to build up the improvements. May I suggest Gorilla Tape Tough And Strong? It is stronger with better adhesive, water proof and UV protected. And wider than most tapes. Taping rims gives you a super light aero improvement. 1000 km on mine without visual degrading ridden only in dry weather you mind. That is on my road bike. Rear disc wheel with foam plate tied to the spokes with zip ties have some 3000 km on my TT bike. Both improvements are massive!
I want to see power graphs, I don't believe her power data, it's a dropout or a power meter sleeping for part of the beginning segment.
@@MrBJPitt Power data would help for sure but position alone can easily account for 30 W and Mark commented on Heather for tactics riding not so aero in the base line ride. Mark was spot on in his observation of Heather not making the "test" scientifically valid.
as for the eastetics, i think you both loose big time. Nice video, though. (as a TO; none of this will pass checking :D )
Oh no don't tell us that ;)
Despite all the entertaining content the only thing that stuck in my mind was seeing Heather’s rig resting its top tube against the utility pole. Maybe it was really resting against the top tube box? Otherwise, please, just no.
