    HI,
    I’m changing from a 140mm disc on the back to 160mm. Can anyone advise which is the correct option here?

    I can’t decide if its the Front 160mm/Rear 140mm or 140mm DM to 160mm…

    If its an IS mount on the frame you need the front 180 rear 160, on a post mount frame you need the 140DM to 160 post mount, on the IS mount the bolts go in the mount from the side and the adapter is threaded,
    On a post mount frame the bolts go in the adapter from the top and the post mounts on the frame are threaded..
    But basically the rear mount is 20mm smaller than the front..
