Anyone know anything about Ambrosio rims? I have Ambrosio CC22 hardened alloy rims. Problem is they seem to be slightly larger than standard tyre sizes. Consequently fitting tyres is a major hazzle. It is IMPOSSIBLE to fit tyres WITHOUT using tyre levers. So I have a whole bunch of tubes that have been nipped fitting! :'( I have blaming the tyres (Continental Traction Pro) but have now discovered by trying to fit my wife's El Cheapos that it is the rims that are slightly oversize. Does anyone have any suggestions?
