Levo Gen 2 clunk from drive train?

[lodom]

I'm getting a cl-clunk cl-clunk sound only in the 7th cog (from the biggest). One up or one down it's quiet. It happens with the motor on or off. I don't see anything odd stuck in the cassette or derailure. That happens to be my "favorite" gear! I'll try to record it soon.

Bent gear tooth maybe?

That makes sense. I did have a crash on some rocks about a year ago that bent one of the spokes. The noise started about 4 months ago.

Nothing bent in the cassette but it may be time for a new drive set since it's making the noise in my most used cog. I'll go ahead and put a 36 on the front while I'm at it. Not sure how to search for e-bike specific components in the US though.

I've been breaking upper pulley wheels. Take a look
