Anyone know where I can get a bargain to service my Trek mountain bike. There is something wrong with the gears it could be a small or big problem. The bicycle shop closest to me Cycle world Burwood charges $89 for a standard service anyone know some where else where I can get it cheaper.
I think the gear chain from the back wheel were moved accidently and now the gears don't change at all properly, as I don't quite know what the problem is it could be a small or big problem.
