I have just put some new Mavic rims on my bike with 20c clincher tyres. The Mavic website recommends a tyre pressure of 146psi?
With my bike mounted pump, I could only get to a pressure which "felt" plenty firm enough to ride on, but the pump kept blowing off the presta valve stem. I borrowed a more robust pump with a crude pressure guage, foot stand and extendable handle and managed to get 120psi (my previous attempt had managed about 85psi). The tyres are now absolutely rock hard and seem almost too hard to take out on the road?
What pressures do you run on and if these figures of 140+psi are correct, how do you easily inflate your tyres? I may not be Arnold Scwharzenegger but I really can't imagine physically pumping past 120psi.
