Tubeless... Is that all?
I switched to Vittoria Corsa Speed G+ 2.0 - tubeless tires on carbon road bike, after years of riding with Continental GP 4000/5000 clinchers. All 23 mm wide, on the same wheels.
After around 15 rides, I can say that I felt no difference in performance. The tubeless generate a different noise, which I like very much - sort of mild rustling that reverberates in the carbon frame, somehow similar with the old (steel) road bikes with tubulars on thin aluminum rims.
But… is that all?
