Fitting a Sram Derailluer To A Specialized Bike ?

[Wester]

Is it possible to fit a Sram +4 rear Derailluer to a Specialized Hardrock bike ? or does it have to be Specialized Derailluer . I guess that it is not possible to fit a Shimano Derailluer to a Specialzed Hardrock bike

Specialised don't make derailleurs, but if they did, they would be the ...... Or sorry, I was thinking of having a drink.

Generally need to keep compatible with the gear levers and cassette, so keep to the same make as you already have, unless replacing the lot.

It is eminently possible to do precisely that. In fact, it probably already has one.

I have a Specialized Hardrock Pro, it came as standard with Shimano Alivio groupset on it, just get like for like.

If u have sram shifters you will have to fit a sram rd. If u have shimano you need to fit a shimano one - pull ratio is different
