IS caliper to Post mount fork: Trawling around I see adaptor for 180mm disc, but not 160mm, so guessing 160 it is not possible??

try this

I have a shimano adaptor which will run a 170mm and matching rotor if you need….

What D0NK said.. although it seems to be a bit hit and miss as to whether it works, depending on what fork/caliper you are using (clearance issues).

Thanks – mrcamel, thanks- interested, but may be limited by the fact my hubs take splined rotors though?

mmmm, yes, you can do splined to 6 bolt adaptor but thats just somat else to buy!

I’ve got a couple of splined to 6 bolt adaptors for sale, still boxed, if you are interested in going down that route

I may be missing something here…

Indeed. Caliper is IS; fork is PM.

You want one of these

I used it to fit a Hope XC 180mm IS mount brake to a set of post mount Rock Shox. No need to go up in disc size or anything. Would work just fine for a set of 160mm

Hey bigG !

I don’t get it.

Is that 180mm adaptor + 160mm caliper + 160mm rotor ?

it’s a post fork to 160mm IS adapter with a 160 caliper and disk I think?
