Hey there, I am having trouble with my profile, it isn't old atall really i got it just before xmas from tarty bikes and it just keeps skipping (loads) and it keeps sort of catching so as i'm rolling along the hub would catch as if it wanted to swing the cranks around i was just wondering if there is a reason it is doing this so soon and once i have fixed it could someone tell me how i could maintain the hub to avoid this happening again. cheers, Nick
