Derailleur Mech

Bike maintenance – changing derailleur (Rear Mech)?

the derailleur on my bike has broken, do i need to replace it with the same one, or can i buy any make or model????
does anybody know any good model??

It doesn’t need to be exactly the same model as the old one.

All Shimano-compatible derailleurs use the same actuation ratio, so they’re all interchangeable. SRAM makes some derailleurs that are Shimano-compatible and some that use their 1:1 actuation ratio. As a rule, SRAM models that have a name (e.g. ROCKET) are Shimano-compatible, while ones staring with an ‘X’ are not. Whatever you get, make sure it’s compatible with your shifting system.

Also consider the quality of what was there before and how much you want to spend. It doesn’t make a lot of sense to get a derailleur that’s 5 levels above all the other components on your bike. And, make sure you get one with the right amount of gear capacity. In simple terms, make sure the cage is about the same length as on the old derailleur.
