Why buy one, when you can make one yourself…or at least that’s what Mark thought! This cost him under £30, and he's had a lot of fun making it.

Great video! But it would’ve been nice to see it compared to a manufactured disk wheel to really compare home made and the manufactured thing 👍🏻
Yes agree with this, test this against those manufactured disc wheel to see result
@@lalateoh9963especially on a hilly course!!
@@lalateoh9963 and if results are tights the wheel manufacturer will immediatley stop his GTN sponsoring for bad advertising ;)
@@simonrano8072 Haha very true
@@elijahkwon422 yupe, really hope can know the result. If positive, we can DIY disc wheel too LOL
The only thing I felt was missing was comparing it to a super fancy proper disc wheel. To see if it's worth the money for the convenience of having 2 different wheels, without need to remove the covers everytime you need them for an uphill race.
They wouldn’t want to piss off any wheel companies. Duh......
No mention if you’re using the same power average over both comparison courses. 🤨🤔
Same watt, same wind speeds, these test should have been done inside on a track over a longer timsspane like 20 min at 250-Watt and 350 watt
i love this channel, but there is no way the "data" taken away from these "tests" can be viewed as valid at all. no repeated tests to confirm repeatability and no controlled environment. :(
From memory this video covers the same subject with more repeatable test procedures.
You should see some GCN does science videos😂😅
@@jamelpiclit3062 Absolutely no science, lol.
There wasn't even the average wattaged of each of the TT runs mentioned.
Thanks for the attempted ^_^ awesome result
I'm in the process of creating a rear wheel disc treatment for my singlespeed. Last night was the first experiment, so far so good. My plan is to stretch window screen over rim, then impregnate the fine mesh with some type of varnish. I started with a 1m ×1m sheet of window screen that I cut a hole in center to fit over axle. I then took an old front wheel I don't mind messing up for this experiment. On said rim I half mounted (just one bead) an old shabby tire to hold screen in place while I stretched it out. This worked well, but later realized rope wrapped around rim worked better, in addition, the rope can be tightend. Doing this actually pulled the screen nice and flat and taught. Now keep in mind this is just an experiment. Next I brushed on Mod Podge, a clear glaze used to preserve completed puzzles. I hoped it would be thick enough to fill the holes in mesh, but after a few coats I knew I needed something heavier. I'm gonna try urethane wood varnish next. I went out today to find the perfect thing. A fellow pointed me to an epoxy product that will actually harden. So I might try that. It would be cool if the disc turned out totally translucent. Attaching this skin to my rear wheel will be simpler on account of I only run a front brake on this bike, meaning I can affix to rear wheel braking surface.
It's 47 km hr head winds, 25 km hr cross winds, 36 celcius, 95% Humidity as of 3:20 pm. Anyone cycling out today ? Zero lol. Imagine the Tour De France having this weather for a few weeks!! 😂
Thats actually preferred weather :/
I used the aerouacket disc cover. It was custom fit and easy to install. That was my compromise to buying a full disc for the back. Makes a bit of a difference but I just think I look faster with a disc which is half the battle.
@@Discovereta make it yourself with some .2 mm carbon or custom your own with the carbon cloth and some resin after you do out a mold. It’s fun and easy, plus the end product is lighter than a proper disc
Yes!!!! More of this!
Oh yes finally !!!!!
Been waiting for it !!!!
It looks like the disc cover also helps you clip in. Double-win!
Matt Dion haha I was waiting for a comment about that 😂
Imagine what it could do for Matt Stephens
Jmaes Oulsnasm let’s not get ahead of ourselves. Stephens would need a three disc tricycle to +1 his clip in skills.
Nice ride
You did 5 km at more than 57 kmh avg speed??With strong tailwind???
My thoughts exactly. The performance of a disc wheel is strongly dependent on wind angle and speed. With a crosswind or a cross/headwind the difference might be bigger.
@@myateem him isn't Victor Campenaerts,there is something wrong,or was very strong tailwind
disc covers have been found to surprisingly perform nearly at the same watts as true disc wheels with the covers only being a few seconds slower over the span of an hour of cycling!
Stumbled over this vid, because want to DIY a Wheel Cover. Wonder if anything changed in maths after leaving school many years ago. 2.1kg minus 1.39kg does not sum up to 71 grams as far as I have learned. ;-)
you should see the vid on making the wheel cover - apparently it is a radius of 28mm (i think 1 order of magnitude adjustment required for both!)
Cool liked it..Cant see it taking off at Kona but it might do for me in Mallorca...Nice keep them coming..
any clue on where to get plastic cover in Canada i cant find it anywhere online
Good vid , test it against a real disc wheel 👍👌
If you want them to be almost permanent the tool would be double sided foam adhesive. It’s strong enough to secure windows on sky scrapers. That’s right, those glass panes aren’t bolted on. Just taped. (Newer ones anyways)
Where do I get that foam tape?
thats a special 3M adhesive strips!! $$$
This is a really useful test, but you do realize you just projected to finish an 180km bike leg in 3hrs9mins taking 1hr off Cameron Wurf's all time record!! That's some saving with a disc cover (3hr13.2min without the disc) ;)
these dudes are fast
Lol, every time I think, if Mark is serious or joking us))
both wheels a disc cover will you go even faster?
Should you do a disc wheel in the front or will that negativaly effect your cornering?
half ironman will not allow front discs, only back ones
Satisfactory, but should've done the tests with dual disc bicycle, since most of the aero forces are applied into front wheel.
GTN DESERVES MORE VIEWS MAN FOR THEIR EFFORT AND HARDWORK
Did you have a tailwind?
what about side wind? will it push u over?
you feel it on the rear, dont use on front wheel it will affect yiur steering
For a pair of Enve 5.6, I would rather get a pair of Bora One 50 and a Vision Metron Disc, as they cost about the same price (Enve 5.6 $2500, Bora One $1500, Metron Disc $1100)
Why is the drivetrain on the wrong side on the front image?
The image was probably flipped/mirrored.
What was your avg speed on the flat test section?
i Saw someone commenting 57 km/h
@@simedinson984 Yes. It was simple math commenting :)
@@simedinson984 thanks. on second look, i noticed that he mentioned the distance - 5 km.
i remember looking at some aerodynamic calculations some time back. it turned out that the break even speed for a generic disc wheel was ~40 km/h. this home made one might have been little heavier, so that threshold would be even higher, but still well below 57 km/h.
He literally avoided all those potholes 😂
I think if you put foam spray inside a disc wheel cover it makes a sound like disc wheels.
How much time does it save on a downhill course?
And are the time savings more or less at the slower speeds of us mere mortals?
Wait, that flat course was really 5km? That would be an average of almost 60kph!
Wind tunnel test?
I'm on it
You should really tell us the power number when you preform the comparison
which sunglasses in this video?
A weight weenie....HAHA
It’s a good idea, I tried making this a few years ago, making it isn’t too much hassle I’d say biggest hassle was cutting a decent circle with a Stanley knife and gluing it into a cone shape like he shows. It did make me quicker but as I took it off and used it again for a few TTs it ended up warping and wouldn’t go flush again the spokes. I think it was down to the cutting and coning. If I did it again I’d try to glue the cone a bit better and maybe store it flat on the floor somewhere I suppose so it keeps its shape. Not sure its something that will last lots of seasons.
If you use ABS you can actually cut up a few pieces of ABS and let these pieces rest in acetone, the acetone will turn it into what the 3d printing community calls "ABS glue", this is perfect for glueing ABS parts together since it basically first melts the contact ABS piece and then "welds" itself to it
This would work perfect for these wheel covers!
You have a Quarq power meter on your Speedmax, why not show that data in the video? I thought it would be relevant to include to show you possibly used less power to hold the same or even faster speed?
What kind of plastic is that?
What was your average power on the flat TT? Was it the same both times? As others have noted, 57 kph is not a typical speed, especially for a triathlete (maybe for a world class time trialist), so the tailwind must've been really something. I'm going to sound like a douchebag, I loved this video regardless, but a consultant from GCN might've been in order ;)
When anything is held together by tape it's not going to be about instantaneous failure but endurance failure. Still wouldn't trust anything held together by a layer of tape for an olympic much less ironman bike segment distance. Probably fine for sprints and stuff but if the tape lets go on a humid day after an hour or two of racing and has the potential to slice up your leg (not sure if he finished up the edges) or turn into a kite or just a massive wheel jamming possibility... is the 2-4 minutes you might save in the best outcome worth it?
OhAiShare good point, must admit I’d probably not risk mine over an Ironman to be honest. It’s all held together by tape
Hoe many month' s does it take to train from a 6 hour 70.3 to a full ironman ? I train 10 hour pw
mark ankone what is your goal? Just to finish the IM?
@@trbeyond my goal is to finish "fresh"
It is going to depend on the course and conditions. But why would you want to do a full IM to finish feeling “fresh”? Isnt the point to race to a level to challenge oneself?
@@trbeyond Isnt the point to race to a level to challenge oneself?
- this is the answer on the question, my challange is that i want to finnish strong ''fresh'' not dead
Unfortunately, all the results are skewed by the passing traffic. Would be great if you could do this on a velodrome.
5th!
Not really a scientific test. All results seen within normal experimental error range.
You need a speed (variety) watts (variety), recovery, temperature breakdown... and much more. Must account for variables. Video is lacking a lot. Not a great video.
