Would this replace a Shimano Alivio on a Giant CRS 2.5 without additional mods?
Front Mech - Shimano C51, Cassette - SRAM PG830 12-28, Crankset - Shimano TX71 28/38/48, Shimano Alivio 24 speed shifters.
Hi there buddy, right, I had a simular problem to the one that your experiening. At the time I was running XT shifters and wondered if I could a sRAM X0 rear mech. Because they use different mechanisms, they wont be compatible. sRAM will work with Shimano rear mechs, but not the other way round.
So, in saying this, you would probably need an alternative.
SLX is only a peg down form XT in the food chain. It's really responsive and they have had really good reviews. And for the money, I reckon there is no other rear mech as good on the market.
I hope this helps you.
