The caliper is clearly not sat correctly over the disc ??
Any ideas ?
Yari probably has a 180mm post mount so you only need a +20 adaptor.
Yeah what Simon says.
Damn !!!!
So what mount do I need then ?
A 180pm>203pm
Or just a standard +20 and a few washers.
Pretty sure it's a post mount for 160. 180 on my Yaris and using a 20mm adapter
You anywhere near Glentress/Inners? I've got a fair few adapters you can play with, must be one which would fit
Yari is 180, so you need a 180-200.
That adapter looks wrong too - the Shimano ones I have are bolt through with longer bolts.

The +20mm mounts are bolt through. That mount is correct for 160->203.
223mm rotor. sorted!
Just to be completely sure... Is your disc definitely 203 and not 180?
This is mine with 180. The mounts look different though.

I did exactly the same last week. Bought a 203 rotor and the straight post adaptor. Rock shox yari mount is 180 so you need the 180 to 203 adaptor:
Yes, I.... ummm... have a friend who made the same mistake. I wonder how many +40 mm adapters there are sitting in spare parts boxes around the world.

Hayes used to make such a thing?
