Generally I'd expect nearly all models of tyre, nominally 28mm, at 75psi on a 19mm internal rim width to come up wider than spec. Some makes/models err more than others.As I recall, the 28 tyres they came with were Mavics, which ran narrow.
I would be riding a rim with a 19mm internal and not the Mavic tyres. I am asking to gauge what clearance there is on different tyres (actual width, not stated width).
Measure the distances between chainstays (1) and seatstays (2) and fork blades (3) at 34cm from the axle.how much clearance is there?
I was going to say that 28s would not fit my CAAD5 but I just had a good look and I think that they would! I Googled it and lots of people agree.it was only the really racey bikes that were very tight in that era, i.e, CAAD series what ever number they were on.
