My bike has SRam X3 gears and a grip shifter. I'd like to change for a trigger shifter. In the bike shop where I bought it, they say that I can change for a Shimano shifter (they don't have SRam). I've read that they aren' compatible.

Is it true? How can I discover if they are compatible before changing the shifter and the grip?

SRAM X series and most (all?) of the road stuff has a 1:1 ratio. Shimano is (I believe) 1.5:1; you are asking for drive-train tuning hell if you mix.

Cassettes, mix all you want. Shifters and derailleurs should be matched.

They do sell adapters which fix the pull ratio. As long as the store installs it properly with an adapter, then I could see this as a viable option. Although I'd take the bike for a test drive to ensure shifting was smooth before paying them. –  Kibbee Dec 6 '12 at 17:21
