The spirit of this board is to compile and organize wheels and tires related discussions.

If a new wheel tech is released, (say for example, TPU tubes, a brand new tire, or a new rim standard), feel free to start the discussion in the popular "Road". Your topic will eventually be moved here!

i think these wheels will not age well.

21mm Internal Width - everyone is moving to iw 23mm/25mm.
carbon spokes. giant is now introducing carbon spokes on their 2nd tier bike tcr advanced sl1/prople sl1.
they ship these wheels with tires the PROS refuse to use . why not ship them with best in class sworks cotton clinchers
26mm tires wtf it is no 2020 it is 2024 28mm is minimum.

the rim shape is good but new wheels from zipp/bontrager/dtswiss are coming .

this is not enough upgrades to last another 3 years.
Current Rides:

So many of these modern wide internal rims still have really narrow externals, making them a bit of a waste of time.

It's been shown 30mm tyres still perform great on the rovals, without the tyre being wider than the rim.

I also don't see carbon spokes as an obvious positive. I think I'd sooner stick with simpler, more durable and probably more comfortable steel spokes.

I'm with you on the 26mm tyres though, I still have the brand new tyres from my SL7 and SL8 packed away.

Eh, 21 internal isnt a problem, external is way more important for performance

Man, I've been holding off waiting to see something new from roval but this made-for-26mm-tires half a decade ago wheel is not it

Might finally be another pair of bora's in my future.

26mm is still great for racing, not ideal for daily riding on bad roads but I guess that's not the intended use with "team" edition. I see steel spokes as a plus, wheels are light enough. Campagnolo/Fulcrum are also sticking to steel.

It reduces the volume of the tire, so comfort and impact protection goes down. And if a rim has a 30mm+ external width, there’s not much reason to limit the internal width unless you’re wanting to maintain ETRTO compliance with narrower tires.

If you want more volume, you could just fit a wider tyre of course.

But one thing that intrigues me since learning 28mm tyres are designed around a 19mm internal and 30mm a 21mm internal and how mounting it wider affects the tyre, is what the trade offs are for mounting a typical narrower tyre on a wider rim.

In theory, a 30mm tyre should be optimal on the 21mm Rovals.

It'll be interesting to see whether tyres like the raceday and z30 start a trend of tyres designed around wider internals.

Too bad there’s no 30mm GP5K TT TR or Corsa Pro Speed, eh?

I guess we know how many watts aerolite 2 saves now (~1 watt as they measure power to spin too) as I imagine the new hubs are less aero. I believe these should be more aero than even the newest generation carbon spokes with lower front area, better aspect ratio, and better shaping.

Shame really, I was really surprised to find 30mm STRs measure 31.3mm on Rovals this evening.

Especially considering the same tyres on 25i rims measures 32.5.

21mm internal is fine, 23mm is good, 25mm internal is too wide for road unless you are running 32mm+ tyres.

Aerolite 2 are 0.7mm thick and 3.1 mm wide. All the other steel aero spokes are 0.9mm thick. Superteam's 5.2mm spokes are 0.9mm which ia a better aspect ration than aerolite 2. Their newest wheels have 4mm spokes that are described as "relatively thin and lighter", if they are also 0.9mm thick, that's pretty much the same aspect ratio as aerolite 2

Jfc ppl are still doing this shit

Pog couldve won that race on a 1990s bike with box-section alu rims. If he's an S-tier gc rider, everybody else at that race was B-tier at best.

Laughable that they are forced to use non etrto compliant combo that's not even listed as approved on their website, yeah...
