I am experiencing some drivetrain noise at higher speed (especially pronounced when bike is in the work stand, not nearly as audible on the road) accompanied by a slight vibration felt from the moment I set the crank in motion.
Sounds like it is coming from the cassette?
The cassette is brand new and just mounted (please excuse my dirty chain...)
The chain is also fairly new. However I do not have my chain stretch indicator at hand to measure it for wear. It shouldn't have more than about 2000-3000 km in it.
See a video with sound here:
Also the pulley wheels are brand new.
Thanks for any insight! :-)
