Everything sold to consumers is marketing. The dimples are legit but the speed you have to be going/gains they would impart is lower than marginal.

Can’t use Conti GP5000 on those, because they require hooked rims. And I never understood the 28mm wide trend. It’s less aerodynamic and 25mm on latex tubes or tubeless has a very low rolling resistance and amazing comfort at the right pressures.

[@Jeppelelle]

Less aerodynamic maybe is true but 28mm has less rolling resistance than 25mm & 28mm. 28mm GP5000 has as lower rolling resistance at 100psi than 25mm has at 120psi. So 28mm is faster & can be more comfortable than 25mm

[@mark13williams13]

I can see the benefit for larger tires running low pressures but I am still not convinced by hookless for road use. Limited to tubeless only tyres and can’t run them at a greater pressure than 73 psi??? I would rather have the security of a hook so my tire doesn’t blow off thanks over a minor weight saving/aero gain. It seems like manufacturers are moving to hookless to save money in manufacturing costs.

[@gcn]

All fair concerns, but 73psi is more than adequate for a 28mm tyre so hopefully that along with the wheels being disc specific should mean that there is no danger of a tyre blowout.

The "hockless invention" sound more like marketing, than real improvement to me. Listened to a podcast with Conti's product-manager for road-bike tires lately and he didn't seem so happy about hookless. Resume more or less was: rim-manufactureres like hookless as it's easier to produce hookless carbon rims, since the design isn't so complex, but it's very challenging to keep the tire safely on a hookless rim with the hight pressures you ride on road-bikes.

You hear a lot from the manufacturers about rolling resistance gains on wider tyres due to lower pressures from bumps in the road getting absorbed, but never about the energy lost that would be propelling you forward on high pressure tyres that is lost in downward compression of the softer tyre during the downward pedal stroke.

When you go 20sec faster in downhill 10km because of tubular vs tubeless how can they sale this? when you ride a bike you dont ride it straight and on flat. When you are racing you are in pack so you dont save really the watts, only if you are in breakaway or front of group... when you need to warning brakes and you loose all tyres surface or tubelesse in one warning brake i dont think it's worth at training. zipp have really good wheel, they have strong hub with low friction. they are affordable and thats why no tubular.

@@jkk916 Here's the thing. I know people say cars and motorcycle rims are hookless, so there's no reason a bike rim can't be. BUT, those applications run much lower tire pressure, and the tires have crazy stiff beads Mountain bike rims, similar situation. Wide rim, wide tire, low pressure, hookless works. Now, road cycling, you're dealing with much higher pressures, and comparitively narrow rims. When you see the 73psi max on these rims, it's because tire retention goes to hell at about 80psi. That's the number that ETRTO uses as a max before a rim must have a hooked design. So, if you're going to limit the psi to 80 or below, the rim needs to be pretty wide, at which point rim brakes (and sometimes rim brake frames and forks) start to have clearance issues. So, you could make it, but there's not many applications for it.....

promised Zipp that I would start commenting on the fact that these wheels suck up water and in even light rain (puddles), become scary to ride fast. And there is no easy way to get rid of the water stuck in the rim even days after riding {you can spin the wheels and bump on the ground for a couple of hours - 80% effective), but really? Others suggest breaking down the wheels/tires and remount, but that's nuts, and you can never wash your wheels.... or worse yet, have to stop to check wheels for water before descending at high speeds if there are any corners Yes, they will drill holes at their factory which is at least something (you have to ship back to Indiana with questionable results and who wants to go without a bike for weeks with a potentially questionable hack).....Granted the new production has holes drilled in but this is a big defect and should be replaced. I might never buy a Zipp or SRAM product ever again. Now for the good part - I really liked (as in past) these wheels and for the $ cheaper performance than their NSW or other exotics. They ride smooth, easy to install hookless, tubeless approved tires (get a booster pump), and the lifetime warrant sounds good, maybe not for design defects though. I've ridden about 2000 miles, and tubeless 28s is the way to go (4 punctures sealed with mucoff sealant). That said, if I had to do it again, I would probably spend even more money for wheels that don't act like sponges.

[@darrylhuculak4996]

It's not just the tires but the tire and wheel combination. The new wheel science focuses on not just the tire but the interaction between tire and rim. If a wider rim can be lighter and more durable, then chances are it will be more efficient with a wider tire. Personally I noticed an improvement a few years ago when I switched from running 23 mm GP4000 at 110psi to 25mm at 100 psi on the same cheap aluminum rims. Faster speeds, smoother ride, and fewer pinch flats. However moving up to a 28 or 30 mm tire (assuming my frame allows it) on those same rims would probably not give me the same improvements because that's not what they were engineered for.

Even though sponsored, this was still 'objective enough' by keeping to facts. Thanks for that! It would appear Zipp has been hearing the chirps from a certain engineer on the youtubes. About time.

Thanks G C we always try to remain objective as much as we can :)

A bit late to see the video. Bottom line, great wheels . Petty about Specialized and their SCS version of diverge ( my case ), as this wheels have the potential for “budget graveling”

[@chemistry9942]

welp there goes my savings again

[@AC-wq7fo]

Between Hambini and Durianrider I done gone and saved me a whole lotta £$€ at 40kmh.

[@RYTHMICRIOT]

I've been wanting a set of ENVE rims for some time but I just can't bring myself to spend the type of money that they demand. Mavic on the other hand, well I just don't dig em. These could be an acceptable compromise.

I'm still riding 23mm tires.....

[@esakhwaja8592]

same, and to be honest skinnier tires always looked cooler

[@antonsegers5507]

Do 28mm tires fit on the backwheel of the aeroad??

[@gcn]

Good question, they should do, hopefully Si can let us know

[@antonsegers5507]

@@gcn I see a 28mm in front, but canyon itself said 25mm is the max size

[@iancanuckistan2244]

Excellent question. My Masi will fit a 28 in the rear but only a 25 on the front and even that is close to hitting the fork.

[@spinspinbaby1531]

2017-latest model should be fit to 28mm (rear) I use 2019 chinese aero road frame with 25mm tire and there's like 7mm space left

[@febrianihsan1962]

I also have aeroad and using this 303s with 28mm tyre both front and rear and its work perfectly

[@immaculatepointless]

Still quite expensive for generic Chinese rims with about the crappiest hubs out there. Without real data published to support their aerodynamic efficiency, there's no reason to get them instead of no-name wheels which cost half the price.

[@nuttynut722]

for the same price, I can sure we would get much better deal at farsport or lightbicycle or whatever, I'm pretty sure they come from the same factory anyway

Need that tech on racing motorcycles wheels.
