more drivetrain noise than mine.
could it be the Redline shockproof gear oil?
Given the weather on the day, that is the soundtrack from the built in microphone inside the waterproof housing, levels set to auto and Redline Shockproof in the bevel box. Doesn't really give a very accurate impression of the noise. Some of the other videos I used an external recorder and a pair of lavallier mics. Which works much better but would have drowned the camera, mics, recorder and I wouldn't have done much better myself!
