dont know if that's ok or not,
what do you guys think, is this normal?

You're listening to the knock.of the cogs around the crank due to it's nut becoming loose I have just retorted and locked mine at 120nm for the 2nd time 10.000miles between and there is no way my nut could of rotated I was talking to someone the other day and the only way this could be happening is the crank is slowly stretching ... which makes sense how can we tighten something and it not rotate but become loose when it's against a stop .... best answer I've heated so far ...... if u luck for a vido on youtube you will find videos under "xt660x knock" both of the noise and what's causing the noise .... the channel name is "Marvy finger bottom" lol don't ask.... may also come up under "bikemad195" can't provide links as I'm laid in bed on my phone lol
