Spent 4 hours chasing a ghost shift on a SRAM GX derailleur before realizing the B-tension screw was loose
Had to pull the whole drivetrain apart twice, check the hanger alignment three times, and recalibrate the limit screws before I spotted that stupid screw barely hanging on, has anyone else had a tiny fix like that eat up most of your afternoon?

Dude that's brutal. I read somewhere that B tension is actually super critical on 1x setups because it changes the whole chain wrap angle, @faith_schmidt is totally right. Glad you finally caught it before you threw the whole bike in a lake haha.

Nah man its actually the b tension screw that sets the whole angle so that makes sense
