haven't used my 456 for about a month or so but went to dust her down ready for a sunday session at westcott and the damn thing is stuck solid! i've taken the cassette off and it spins with the usual clicks but also turns the axle. Is it buggered? anyone else had the same problem? I've dropped it off round my LBS who are going to have a look tomorrow morning but i'm hoping it's not knackered!
