I have just set my gears up on my bike, front and rear mech from scratch and new chain and cassette and everything is changing as it should be but i have a big issue when im in the middle chain ring at the front. If i apply a certain amount of force when cycling along the chain jumps down on the bottom ring but from the bottom and not the top of the front middle ring what can be causing this anyone got any ideas ?
