I just cannot afford a new set but I need a set of reasonable lasting set of 700x23 tyres. The only tyres I use are of course Conti GP4000 or GP4000s. I've tried Bontrager, Schwinn and Pro3s and they hardly lasted a few months doing around 200km a week. The GPs outlast them all and my pair I had for over 5 years!
So if you have a spare old set with the ridges still intact, I would really like to hear from you. Thanks
