Shifter/Derailleur Compatability SRAM-Shimano

605 Views 3 Replies 3 Participants Last post by  robs31
Right now I have Shimano combo brake/shifters and am looking to upgrade to hydros so I will need to get some shifters. It seems that some of the SRAM stuff will work with the Shimano derailleur's I have but cannot confirm what the differences are. Any help there would be appreciated.

Any of the 'named' SRAM (ie MRX, Attack) will work with Shimano.
The numbered models (ie X7,X9) will not.
The differences are in the cable pull ratio.
SRAM= 1:1
Shimano = 2:1
Sram Attack Trigger shifters are compatible with Shimano Derailleurs.

Oddly though Sram Attack Trigger Shifters are NOT compatible with Sram Derailleurs. They are made specifically to work with 2:1 Shimano Derailleurs.
Thanks guys. I saw the different ratio's and thought that might be it.
