Light Bicycle have R45 and R55 models that should meet your dimensional criteria for reasonable $

Probably not as swoopy of an aero design as the latest tech...take a gander.
These? https://www.lightbicycle.com/U-shape-35 ... tible.html
Not sure if the 25 outer would be wide enough, maybe with 23 Power Cups

dexvd, look at the schematic of the R25-45 and the R25-55 on the LB site. The width of both increase to 27.3 and 28mm respectively. I'm only saying these appear to be about what you are looking for from a dimensional standpoint...I'm neither pro or con on these for your application. Weight-wise they do not seem overly svelte. As an aside, I have a pair of their AR36 rims that have not been assembled yet. These are 21mm internal and 28 external.

Oh interesting, I see the R45s look like a decent option as they balloon out more than the R35, seems like the best affordable option I have seen so far. I had thought Reserve's new turbulent aerodynamics wheels balloned out similarly and it was a novel thing.

Measured width of 25mm Power Cup is 29.8mm on LightBicycle AR56 with 23mm internal and 30mm external rims. 74 psi. Almost new with just 200 miles on the tires.

Can I check if anyone here use the 23mm Power cup clincher? I've both the Tubeless and Clincher in 25mm, both inflate to 28.4 to 28.8mm respectively on my 20/21/22mm inner rim width wheelset. Looking for something that inflate to 26mm for a 20mm inner width rim.......I've the conti GP5000 S TR 25mm and the ride is petty rough compare to the 28mm S TR...just wondering the 23mm Michelin will come to about 26mm+ when inflated to 75-85 PSI

I have a 23 on a 19 (internal), 26.4 external and they measured 25.2 after few rides at 6.2bars (90psi), I will check later to see how they are after roughly 2000km.

Edit: 25.45 on one and 25.5 on the other after 2000km

Anyone tried the 30mm TLR version, how big that one comes out on 21/23 ID rims?

Are these tires easier to mount than the GP5K? Been running contusion for years but I had the rare double flat two weeks ago and I hate how damn difficult it is mounting continental tires, the GP5K is awful in this regard.

easier for sure vs GP5000 TL or GP5000 STR

Hi, does anyone know how wide a Michelin power cup TLR 28mm would measure on a 23mm internal rim width? I have the new Enve 6.7 SES that have 23 inner rim width and 30mm outer rim width.
Making a choice whether I should use the gp5000 S TR 28mm which are "true to size" when seated, and so would be more aero for that 30mm outer rim (a bit faster than Michelin power cup TLR but less grip and puncture protection) or use the Michelin power cup TLR 28mm which would likely inflate to 31mm if not more (not sure, hence why the question) and hence ruin the aero profile of the wheel.... but be more puncture resistant and offer more grip... any thoughts on the inflated/measured width of the 28mm for gp5k s tr and Michelin power cup TLR?

Thanks!

Take any of the measurements from a 21mm rim earlier in the thread and add 1mm. That will get you a very close approximation.

Surprised you mention the conti 28 are true. I used a pair of wheels with 28 gp5 that measured 29.3 on a 21mm rim (measure taken after second ride) on a 23mm rim they should measure 30…

A Michelin cup 25 will measure around 28 once installed. That’s the narrowest tire you can mount on a 23mm rim as per Etrto norm. Worth mentioning that by opening so much the tire you may expose more the sidewall since it’s less protected than on other tires.

on 21mm inner width Shimano Dura Ace rims --> my 28mm Conti STR measure 28.8mm and 25mm Michelin Power Cup measure 27.7mm
on 22mm inner width DT swiss ERC rims --> my 28mm Conti STR measure 29mm and 25mm Michelin Power Cup measure 28mm

I like the ride quality and traction of Michelin way better than conti 5000 STR.
I think the Conti will be more robust adn Michelin will not last longer than Conti.......let's see

I’m still wondering how BRR and I have found 25mm Power Cups to measure much wider than others. My 25s measured 29.3mm on 21mm (28mm external) Aeolus RSL 37s. BRR’s 25s measured 27.7mm on a 17.8mm rim.

How is the same WAM being achieved on both 21mm and 17.8mm rims??

And my opinion on the tread width still hasn’t changed.
