These are the derailleurs I've got on my Iron Horse Warrior 3.3:
Front - Shimano SIS (I know, I know. Wretched things won't even shift!)
Rear - Shimano Acera (Decent)
I've concluded to get Alivios on both ends. Now, overall, are the Alivio's any good? And will my shifting on the rears be a little smoother than the Aceras? Shifting while standing lacks fluidity sometimes.
I mainly do XC and light DH riding.
Also, if I get the Deores instead, will there be any significant difference?
