Some frames or forks have the mount at a different position to standard, such as "Plus 20" on the rear of many Inspired frames, or 180 Post Mounts on a lot of modern MTBs, so please follow the guide below to ensure you order the correct item.
First, identify which type of frame or fork you have - IS (International Standard) or PM (Post Mount). IS mounts have 'sideways' installed bolts, in the same orientation as your hub axle. The PM system uses radially mounted bolts, roughly in the same orientation as your spokes.
Then, measure from the centre of your hub axle to the centre of the nearest caliper mounting hole if you have an IS mount, or the top centre (where the bolt screws in) of the nearest mounting hole if you have PM. This will tell you which disc mount position you have:
160 PM fork = 55mm
180 PM fork = 65mm
IS Fork = 50mm
+20 IS Fork = 60mm
160 PM frame = 55mm
180 PM frame = 65mm
IS frame = 40mm
+20 IS frame = 50mm
Then, find your rotor size below and read off which adaptor you need:
160mm front rotor with:
160 Post Mount fork = No adaptor
180 Post Mount fork = Not possible
IS fork = Adaptor A
+20 IS fork = Not possible
180mm front rotor with:
160 Post Mount fork = Adaptor L
180 Post Mount fork = No adaptor
IS fork = Adaptor F
+20 IS fork = Adaptor A
200mm front rotor with:
160 Post Mount fork = Adaptor M
180 Post Mount fork = Adaptor L
IS fork = Adaptor N
+20 IS fork = Adaptor F
203mm front rotor with:
160 Post Mount fork = Adaptor C
180 Post Mount fork = Adaptor H
IS fork = Adaptor B
+20 IS fork = Adaptor J
160mm rear rotor with:
160 Post Mount frame = No adaptor
180 Post Mount frame = Not possible
IS frame = Adaptor F
+20 IS frame = Adaptor A
180mm rear rotor with:
160 Post Mount frame = Adaptor L
180 Post Mount frame = No adaptor
IS frame = Adaptor N
+20 IS frame = Adaptor F
200mm rear rotor with:
160 Post Mount frame = Adaptor M
180 Post Mount frame = Adaptor L
IS frame = Not possible using items we sell, and not recommended as it is highly likely to break your frame
+20 IS frame = Adaptor B
203mm rear rotor with:
160 Post Mount frame = Adaptor C
180 Post Mount frame = Adaptor H
IS frame = Not possible using items we sell, and not recommended as it is highly likely to break your frame
+20 IS frame = Adaptor B
If you still aren't sure which one you need (appreciate it is a bit of a minefield!), please feel free to contact us for advice.
