I don’t get stumped often, but I’m stuck here.
2018 Giant Trance, Sram Eagle GX.
Under load, the chain “pops” on the cassette, as if it comes misaligned and then snaps back into place on the cog. Not quite as heavy as when the chain almost shifts to next cog, but definitely sounds and feels as if the chain is coming un-meshed from the teeth and then popping back into place. This happens in most of the cassette, so I don’t think it’s the “teeth tolerance” issue I’ve seen people discuss regarding a specific cog.
Bike pedals and shifts flawlessly in the workstand.
So far I have checked/confirmed:
Cassette does not appear worn
Hangar is straight
Torqued all suspension pivot bolts
Torqued rear through-axle
I’m stumped and it is keeping me from riding in beautiful weather because I can’t stand a noisy bike.
