R3 tire size limit

G’day Guys,

Since the r3 has been used in the roubaix a few years I figured you should be able to safely fit a larger tire in the frame/fork. Does anyone who owns a R3 use or know if you can fit 28mm wide tires in there. I frequently run 28 tire for comfort and durability in training and was wondering if that if I could do that in a R3.

Thanks in Advance

Peace
Peter
