Sorry for the camera work, wasn’t easy to record one handed in the small parking lot.
Bike is a Trek Fuel Ex 8
When I’m coasting the cassette jerks for a moment. It seems to be doing it precisely once per rotation.
And somehow I can only reproduce it when in the highest gear (so smallest cog wheel).
Nothing particular has happened to the bike today. I’ve cleared a bigger drop but that was it. I only noticed it at home.
