Optimal rim width for carbon tubular race cross wheels?
I am looking into various carbon tubular wheels to use for racing cyclocross this season. I am new to the sport, so am not sure what width to go with. It seems like rims are getting wider and wider.... will the extra wide rims work with 32mm tubular tires? For example, I am looking at different wheels that are 25mm and 27mm wide. The best deal appears to be the 27mm wide rim, but damn... I have never heard of wheels that wide before. I would hate to get them if the best tubular tires are designed for 23mm rims and are not compatible with 27mm. My cross bike has cantilever brakes so braking surface is key.
I am in general looking at some carbonzone chinese wheels, or may keep my eyes peeled for some much older used zipp 303's.
