well one of bikes has fully rebuildable ones(apparently) so you can replace the outer rather than the whole lot...meant to be cheaper.

it was a very slow slide, nothing spectacular really.

To allow for expansion due to heat without warping. Some clearance (rattle!) is fine.

Cheaper is always good

IME it is the inner (carrier) which gets the profiles of the bobbins battered into it allowing front>back play rather than the friction material getting worn away.

Do they do both the discs and carriers separate?

Dunno Chris, absolutely no idea. Not that I'll need them replacing any time soon, I hope.

WELL

ive just got back from bike shop number 1 and the alignment is spot on and the computerised thingy confirms that everything else is 100% sooooo will try bike shop number 2 tomorrow and see what happens with the balancing etc. after that im at a loss.

Sometimes you've just got to change the bike, or it will always nag at the back of your mind.

It wont if its fixed
