Be interested to know how you get on fitting those Challenge tyres. Mine were an utter pain in the arse to get on the rims, dreading a puncture. Tried on both a set of Hunts and a set of Mavic Ksyriums and they were as tight as fook on both.
Fitted them to a set of enve 3.4's to stretch them out a bit today, as you got me worried they would be a pain to get on.... but they went on super easy without any drama! No stretching needed after all.
