    Trying to sort mates bike out. Sram X7 shifter and I’ve bought an alivio front mech.There were no instructions so taken a punt on cable routing on the mech, is it right? When I shift into middle ring it throws the shifter too far and chain jams against the middle ring so I’m guessing it’s pulling too much cable.
    I’ll try and attach a pic.
    He’s picking the bike up later so hope I can get it working for him…
    TIA

    is the shifter high enough ?

    Is it adjusted properly for the inner as it may be too far over to start with ?

    Pics will be massively helpful but if the lever moves it the routing is probably ok so it just needs setting up properly moving the adjust screws that are on it somewhere

    see those two screws above it one adjusts the trim for inner and one for how far it can move – ie outer fiddle with them – undo cable first and use guide above routing looks fine to me

    Aren’t SRAM and Shimano pull ratios different and therefore not compatible.

    I’ll have another look at the cable tension, I slackened it off to get enough clearance off the gr
