I have two bikes at the moment (Giant XtC SE3 with marz AM3's and big 8inch rotor disc brakes 'the name of them evades me', and a Specialized P1 All mountain, with Marz AM SL's and AvidJuicy Carbons etc) and im jonesing for a full susser Kona so no doubt ill soon have another bike floating about with 8inch rotor on the front.

I use my two bikes quite a lot and have several different roads, trails, downhill tracks etc around here that allow me to get a good mix of riding. One thing is though im really wanting to have the ability to switch around wheels, so i can have a set of wheels from the xtc with semi slicks, and the rims on the specialized with burly 2.4 mud pluggers because i hate changing tyres before a ride. Only problem is the avid's have a 6inch rotor on the front, so i need a new disc and an adapter presumably to be able to run the same wheels on each bike. Do they sell adapters for such a conversion? Ive checked all the websites in the uk and turned up nothing.

Thanks.

yes you can get and adapter to run a 203mm rotor, however many manufactures don't recomend putting a 203 rotor on a qr fork, they will list a max disc size. You still do it, specialized actually has a bike that comes stock with 203s on a qr. Just be aware what ur doing

do you have post mounts or disc tabs?

That's a load of bull anymore. They don't make the forks like they used to when it was the norm.

my 2008 fox f120 said max disc 6" I'm not saying you can't run big discs, just to be aware of what the manufacturing rec is

Fox says 6, but you'd be fine with 8.
