Hi All looking for a bit of info ... i recently had these put on by a well known fitting outfit and on checking them before going out riding the other day i find that the rear has started to crack down the centre groove. The pressures are fine and they stick like shit to a blanket..... what i want to know is this normal (the cracking that is .... ) after 120 miles or so of riding? I'm thinking not. They were put on in may.
cheers all Marc.
