    Bronson and XX1 10T cassette with chain clearance???

    My friend just got his Bronson and setup with full XX1 groupset.
    After few rides, we notice a click every now and then but couldn't locate where it is coming from.

    Washing his bike the other day and we notice that the chain kind of grind the upper dropout (around 11 oclock if you're looking inside the drive-side dropout).

    The clearance between the chain on 10T and the frame is only about 1mm.

    Does anyone have encounter this?

    Apologies, pictures to follow soon.

    Mine has a decent amount of clearance and no grinding. What hub is he running?

    These types of issues happen with 9, 10 or even 11 speed when the number of spacers under the cassette is incorrect.

    Take the cassette off. If there's a 1mm spacer, remove and retain it. On some hubs there could be a spacer under a dust shield as well, and this would be described in the manual for the hub / wheelset. I wouldn't expect this given that XX1 has a unique freehub body / driver.

    But either way, this isn't specifically an XX1 issue when you have a cassette too close to the frame.

    There are not any spacers with the XD driver. Without photos, I'd lean more towards the end cap not being the correct size and when the skewer/maxle is tightened it's pulling the dropout in too far. Without the maxle, is there clearance between the endcaps and the dropouts?

    Is your wheel hub spacing 135/12 that would explain the problem.

    Yes... yes, it would.

    Possibly, but there would be zero clearance (not the 1mm it currently has) and the 10t cog would be rubbing the frame. There is usually 3-4mm of clearance if everything is setup properly.
