• Just building up a spare parts bin build with a mix of sram MTB shifters, sram rear mech and shimano front mech. I know it worked in the past with my old XT mech but this one is a tiagra. The rear is fine and I’ve got the limit screws set for the big and little rings however I can get it to shift into the middle rings. Too much tension?

    Not tension. Something else.

    In the front or rear?

  • Triples are pretty fussy about the shape of the mech cage, so you're unlikely to get good results using a completely different mech.

    Especially if you're trying to use a double-specific mech on a triple.
