• Shimano R785s. Can anyone explain to me why the calliper is only contacting half of the disc rotor? Was fine with the same adapter and spyres. Looks almost like it would work without the adapter, but then it'll never work with 140mm discs which is what it was designed for?

    Identical issue on the front too. I'm sure I've just set something up wrong, but dunno what

  • Is the adapter mounted backwards? I can see an arrow on the adapter that I would expect to point forward. It certainly looks like it would bring the calliper into the right position.
