I know the Alfine comes with the ability to work with disc brakes but my question is. Can you use any 6 bolt ISO disc brake on the hub? Looking at all schematics it looks like you have to use a Shimano supplied disc brake, however, also on the schematic it looks like the inside of this may be removable and you can add your own disc brake?? Or is the shimano one fixed directly on there and you cant remove it?
Thanks for any advice.
