1x won't go into 10 cog
About a month ago I went to a 1x setup (sram red e1). I've put roughly 1k miles into it over the past month, love it, and wish I would had gone 1x sooner on this bike.
Only issue I've had happen, is the bike will randomly refuse to go into the 10 cog.. I get the flashing red/green lights on the RD, like the bike thinks I'm in the small chainring trying to go small-small.
To fix this, I've had to put a battery into my uninstalled front derailleur, and "shift" the FD. The bike will then go into the 10 cog like normal.
I've been all over the AXS app looking for a way to specify that I'm running 1x, can't find anything. I've deleted and re-paired the bike to my app, still no hope.
It's a weird issue as it has only happened a few times over 1k miles.. it's still something I'd like to fix and not worry about it happening again.
What am I missing?
thanks in advance.
UPDATE:
I did re-pair the rear derailleur and shifters, now the FD is no longer showing up in app. Hopefully that has fixed it! Thanks for the help.
