Trying to figure out a slight problem I’m having with a Sram NX eagle install. I have some chain noise in the lower gears. Shifting through the hole cassette is butter smooth. B tension is good. Chain length looks good here are some pics.
The rear hub is a bikehubstore M270 which has been great for a low end mountain bike hub.
Waiting for the steel free hub body to come in stock also changing the aluminum axle to a steel version and new bearings. well i don’t think the hub is the problem. Any help much appreciated.
Chainline is a good start for sure. Are you using the SRAM chainring? If not, does your ring have the correct offset? What cranks?
The chain length looks ok, could perhaps lose a link yet. Unless this is a dually, where you need to account for dynamic ride position vs static. B-tension is clutch on the 12 speed stuff and every turn to adjust it affects position and cable tension as well. I find the upper limit needs to be adjusted in tandem with b-tension.
You’re welcome to pop in and i’ll help you get it dialed @carpetbomber
