• Probably one for the mechanic's thread to be honest. But with the chain on it behaves the same. Easily shifts off the biggest cog, the limit screw is at one extreme. It takes about 10 clicks on the micro adjust for it to shift into the 11T. Def seems like the mech is mounted too far inboard.

    Edit - I'm switching the groupset over from my Fairlight Strael and they have confirmed that they swap out the road link type bit for their own custom one. They think it's very likely that could be the cause. They have an original they can give me.

  • have you started from scratch with the di2 app ? whatever was setup in the software for the previous frame might not be adjustable with the micro-adjust

  • You’re right to look at this mechanically and ignore the Di2 aspect. Possible causes include.

    • Bent hanger
    • Chain too long
    • Cassette too big
    • B screw too far out
    • Cassette not mounted properly
