I have noticed an issue with my XX1 42 tooth cog.
I have a couple climbs in my area that are about 45 minutes long all in 42 tooth cog.
When I am in this gear, if I back pedal (which I will do to get the pedal to a starting point after a break or getting off for an unclimbable section) the chain drops down to the 36 tooth cog.
I put the bike on the stand and the same thing happens. Won't stay at 42 tooth backpedaling.
I adjusted the derailleur perfectly to no avail. I have a 32 front tooth, 168q on a carbon Bronson.
The chainline angle seems to steep and just wont stay where it should.
Anyone else noticed this or been able to fix?
