Any chance that Avid or Hope +20mm adaptors are going to work with new XT Brakes?

I could save myself £20 if they will.

Front Post – IS Rear

used hopes before the mechanics is the same (from what I know)

yeah theyre just spacers that goes up in 20mm increments

kimbers – that’s fine as long as the bolts for the caliper bolts are a standard spacing (guess I’ll find out easily enough)……ah, they have to be, to fit frames without adaptors (d’oh)!!

But i guess Avid adapters are slightly more than +20mm due to their rotor sizing? 185mm etc

the bolt spacings are mostly standard these days except for the old Boxxer mount and a Marzocchi mounting

Hope work fine on XT calipers with either 183 hope discs or 180 Shimanos.

Avids are 185 rotors, but they’re designed to be used with a pile of washers under their calipers so ususally work Ok too.

Great, thanks. I’ll try it later before order any Shimano parts.

if i’s no good, i have a front 180mm shimano adapter that’s only about 6 months old that i no longer need, that you can have for a fiver?

My mate fitted Avid mounts to his XT brakes. All was well until one day he had no braking power but loads of lever feel!
Turns out that the Avid mounts sit Shimano brakes a few millimetres too high and as the brake pads wear the unworn parts of the pad meet each other and the brakes stop working!!!

I had avids on my Giant reign,swapped my avids with my old XT’s.well old as in on a different bike,for some reason,my rotors were 180F/170R but just bolted my calipers straight onto the adapters that were already on the bike,lost the avid washers though and not had any problems and been on for 6months

Didn’t some Hope rotors used to be 183mm?
