Rides and shifts fine
Getting out of saddle changes it a bit, doesn’t completely eliminate.
Checked spoke tension. Not 100% perfect but no obvious major problem
took off mech and checked hanger alignment
chain’s a bit old but should be ok
Pedals seem fine and secure. Pretty new.
BB is 6 months old. T47.
Jockey wheels the same
Thru axle is tight
haven’t checked the cassette is 100% tight but is also only 6 months old, installed by LBS.
