Tire and frame clearance
Moderator: robbosmans
I just received my new set of wheels: DA-7900 hubs, Velocity A23 rims and Sapim Laser spokes. A beautiful set of wheels if I may say so myself. When paired to my Continental GP4000s 25mm tires, they create a smooth transition between tire and rim. On the rims, the tire is ~ 26,5mm wide.
My problem is that this setup does not work with the chainstays of my current bike, a Scott CR1 from '08. It barely touches the frame most of the revolution.
An option is to try 23mm tires with the rims, but it feels weird to go up a dimension on the rims and go down a dimension on tires in order to get the setup working. Another option is to look for a (cheaper) frame with more tire clearance. But the main issue is that the majority manufacturers don't list the tire clearance. Two of the frames I've searched for are Canyon Ultimate AL and Cannondale Caad10, with mixed results.
Do you really have to buy something like a Surly Pacer in order to make use of the wheels!?

Go with the 23mm tyres?
Even if manufacturers listed the clearance, that would not be exact science, since the actual width depends a lot on the tyre in question, and rim it's being on.

Modern road bikes are generally not designed for tires over 25mm... There are many tradeoffs a frame designer has to consider in the design process.
