Hi, i swapped a X01 RD for a AXS GX RD, i used original chain then set the B tension with the provided tool and all worked fine for me..
Backpedaling my be a chainlink issue. It may go away as you wear in your chain and and largest cog.My wife got me the XO1 AXS upgrade kit for Christmas. I have a couple of questions related to installing it:
- My bike is fairly new, has an X01 drivetrain, and only has about 130 miles on it. All of the install videos mention sizing the chain correctly for installing the kit. Is there any major difference in chain length between the original x01 and AXS version? Just wondering if I should get a new chain before attempting the install. I do not have any extra links for the chain.
- Starting two rides ago my bike has been dropping the chain off the largest gear when backpedaling. Does this sound like a chain fitment issue? About the same time I also had a slow speed crash onto the drive side. I have been thinking the hanger might have a slight bend to it so was going to get the Park Tool derailleur tool. There seems to be a lot of differences of opinion on chain dropping with some saying it is common on 1x and others pointing to various issues. Just trying to figure out the best/correct order of steps to look at since I am going to working on the drive train anyway.
Thanks for all of the input. Questions on the derailleur hanger - if it is bent is it better to replace it or try to bend it back? Do they all need some adjustment when on? It looks like all of the videos show the hanger being bent while on the bike. It is the sram universal hanger.
I always have a backup hanger for all of my bikes, I usually ride with it in my tool kit.Thanks for all of the input.

Everything should be XO1 per the specs. Is there a way to confirm the version of the chain?Chain length stays exactly the same
your chain dropping issue could be a bent hanger or your derailleur could be misaligned.
Also what chainring are your using and on what crankset?
