SRAM and Shimano front derailleur compatibility.

Posted on
  • I know that SRAM rear derailleurs aren’t compatible with other shifters, but what about front derailleurs? I need a top pull front derailleur and I have a Shimano one. I’m using SRAM bar end shifters. Is the cable pull the same? And vice versa, will a Shimano Alivio trigger shifter work with a SRAM Rival front derailleur?

    EDIT:To clarify, on one bike I have SRAM 500 TT bar end shifters (not sure if the left is indexed, I’ve never used it) and want to use a Shimano Alivio 3x front derailleur to possibly make it 2x9.

    Other bike has Shimano Alivio 3x trigger shifter, was thinking of using a SRAM Rival (or really old 105) front derailleur to make it 2x8 or 3x8 (I never use the granny gear, so won’t mind if I lose it).

    Or I just leave everything in place and buy a cheap narrowwide and go 1x9.

  • I don't know if it helps you any, but I'm using a Microshift friction bar end shifter for Shimano MTB 2x/3x with a Shimano 105 road 2x derailleur, and it works fine.

    My point is that I have the feeling that if the bar end shifter is all friction anyway, pull ratios don't really matter? But could be completely wrong. In my case it works.

    @edscoble definitely knows about this, I'm sure.

  • If SRAM bar-end shifter is friction; correct, doesn’t need to be like for like.

    SRAM TT500 front shifter should have a friction option I believe:

  • From my experience Sram front mechs are crap so I’ve always used Shimano ones with Sram shifters and they work well...
    Never used a triple but assume the reason the back plates are deeper is to assist the chain onto/off granny ring - beware dropping the chain onto the bb shell if you’re using a front mech for double chainrings 🤷♂️

  • Ah, yeah, didn’t think of that.

    I think I’ll just go 1x9 or 10 and buy a cheap narrow wide and maybe a bigger cassette later down the track. I know the Shimano triple works on its current bike. No point have two bikes that don’t work properly.
