Both sides or just one ?

Sounds like something is not running true somewhere.

Torque for the bell to rotor bolts is only 12-15Nm (as explained in the technical pages on the website).

The CD supplied goes through it in photographs, but your correct the bell is supplied tight in that kit. Better tight than rattling round !! The back of the bell is faced off flat so thats impossible for it not to sit flat if its on correct.

As your rotor is binding it sounds like a possible classic case of the bracket being fitted on the wrong way round.

I will get a picture for you in a moment..

If there is any concern over a technical fitting issue please use the technical support helpline number on the website as thats what its for !!

The arrow on the bracket points in towards the hub and up towards the sky.

Is it the 16" kit or 17" kit ?
