Hi guys,

I have just started my rebuild of my 'new to me' MC21 SE.

I have bought a Rental rear sprocket to replace the manky one currently fitted.

The existing sprocket has threaded lugs on it that locate in to the cush rubbers.

The threaded lugs have a 21mm nut on the back of them, but don't actually seem to be threaded into the sprocket, and they really don't want to come out.

What is the process for removing / and fitting those to the Renthal sprocket, or do i but new ones separately? If so, where from, as i can't seem to find any?

Any help much appreciated.

Cheers,
Max
