    M9100 12 XTR quick link compatibility with narrow-wide rings

    Just a data point, might not affect anyone else. Only a concern if you are not using Shimano M9100 rings with your M9100 chain.

    I measured the new Shimano CN-M910-12 quicklink at 3.52mm between the plates when installed on the M9100 12s chain. That was too narrow to fit over the ~3.70mm wide teeth on my Wolftooth 96bcd (M9020/M9000) chainring. Had to file down each of the wide teeth to about 3.45mm.

    Obviously the new M9100 chainrings are fine. But if you plan to run a SRAM 12 compatible chainring, you might encounter the same problem.

    SRAM 12s chain quick link is ~3.72mm between plates, for reference.

    In case you are wondering why I didn't just use M9100 cranks, they are not offered in 180mm which is what I have run for 30 years on all my bikes. So I'm running M9020 XTR cranks.

    So did you use a SRAM link with the Shimano chain?
    Did that work for you?
    What chainring are you using?

    XTR12 chain. Have not tried the SRAM link yet. Wolftooth released XTR12 compatible rings so that's what I'm running now.

    A few others have successfully used the SRAM link with SRAM specific N/W rings. Thread here: https://forums.mtbr.com/shimano/2018...d-1078845.html

    Yep, using an XX1 quicklink with the XTR chain and an Absolute Black oval ring. Works great.

    Santa Cruz is offering a new XTR build that features the M9100 chain, and an E13 TRSR carbon crankset with one of the E13 chainrings that they say they looked into extensively and is compatible...I asked but didn't get word on the link they are using...

    will ask again about this specifically

    Can you elaborate on your setup, are you using a SRAM Eagle 12s rear cassette?
    I am on the fence with these new cranks because not sure if I can use M9100 crankset with SRAM Eagle X01 rear cassette and sram derailleur.

    I was under the impression that the shimano chain on a sram cassette will cause accelerated wear due to the chain being narrower than the teeth..

    "This particular chainring will ONLY work with CN-M9100 chain due to different thickness of the teeth."

    I am hoping that someone will release an M9100 chainring that uses SRAM tooth profile so I can use my drivetrain...
