Oh having a bit of a pickle choosing the right brake mounts for my hope E4 Calipers that are on order.

Both ends are post mount. Rear i will need a 160 to 180mm adapter and for the front a 180mm to 203mm adapter.

If shimanos work then i am golden but if not can anyone please point me in the right direction. These are the following from Hope.

Available Mounts:
Mount A-Post Caliper to IS (F-160/R-140)
Mount B-Post Caliper to IS (F-203/R-183)
Mount C-Post Caliper to Post (F-203/R-203)
Mount D-Post Caliper to Boxxer, pre-2010 (F-203)
Mount E-Post Caliper to Fox 40 (F-203)
Mount F-Post Caliper to IS (F-180/R-160)
Mount G-Post Caliper IS (R-203)
Mount H-Post Caliper to Post (F-183/R-183)
Mount J-Post Caliper to IS (F-183)
Mount K-Post Caliper to Post (R -PM 140-PM 160)

So your frame is 160mm post mount & your forks 180mm?
Mount H will give a 20mm increase in disc size front or rear so you might need to use a 200mm front disc.

Second the H mount, run the same as you on my bike.

Nice one, cheers all. Finally got my brain in gear and figured it out.
