It could also be from a saddle too low. But it'd probably have to be almost two inches too low.
I had switched my gravel bike road wheel gearing from a 12-25 to an 11-34 and have been riding that bike more, it has bigger jumps between gears, so might be I’m pushing more. I usually ride a 11-30 12 spd bike, it’s in for repairs. I just switched back to the 12-25, and raised the saddle a bit, will test ride tomorrow. My saddle height has been the same for many years. New saddles though, might be a slight position change. Or I might just be old and having body parts failing.
