I am looking to upgrade the stock alivio RD and am curious about the differences in the 1:1 and the rapid rise systems. I think I know the rapid rise RD has a return spring that helps with downshifting? So does that mean the 1:1 doesn't? Also, will a 1:1 RD work with rapid rise shifters? and vice versa. Basically should I be looking specifically for a rapid rise system (that's the shifter setup I have), or is it a universal thing and only matters on the derailleur end?
On another note, how do the XT's ride? I want to keep it under $100USD so the XTR/X.O parts are out of the question. Any others I should look at?
