There is really not a tubular "standard". You can get tubulars in various sizes as well. I have a set of those Vittoria tubulars on my my track bike (220psi, baby!). There is a compromise between comfort and performance. In a nut shell:trener1 said:I guess my question is...
In clinchers for the most part, people ride 23.
Is the standard in tubies 21? or is this something just in Vittoria?.
Well, this is just plain wrong, or at least not right. Smaller tires means higher pressure (to prevent pinch flats) and so poorer traction, lower comfort, quite possibly more rolling resistance (due to higher pressure tires "bouncing" off road surface imperfections), and faster wear. Smaller tires do weigh slightly less, and on the front wheel can give a slight aero advantage.JaeP said:In a nut shell:
Larger tires = more comfortable ride (lower psi)
