Hi all, Looking at getting a tubeless setup on my Roval CL50s and am wondering what the best option is for tyre width. I have run into a deep internet rabbit hole and have not come up with anything definitive. I’d like to have the most aero set up on these, and would presume that 26s would be more…

I have the same wheels and the Specialized 26 Turbos measure around 28mm.

I have the same wheels and the same answer. The 26s are 28s on the rim. Also, the Turbo Cotton is hands down the best tire I’ve ever ridden.

Cotton Turbos for life. Absolutely love them.

Same wheels running Spesh Turbo 26s. They come stock that way because as mentioned the 26s when on the rim measure ~28. If you look at them, you’ll see that the 26 mounted looks to be roughly the same width as the wheel which is what you want in terms of aero.

Those wheels have been designed to work best with Specialized 26mm tyres.

Slightly off topic but how much of an aero penalty would be to fit 28s instead of standart 26s on my clx64s?

Next to none. But beware, they are very big once mounted on such a wide rim. They were too big for my Ultegra R8000 direct mount rim brakes.

Cotton turbos here too, based on grip, rolling resistance, feedback and longevity, all score 10/10.

If it’s not broken…
