Not to much. I can't remember the exact amount I took off but basically two cuts. One on the back side for the axle mount to clear the inner hub spoke retainers (had to trim the screws too) and the other on the front to match the exact length of the axle spacer.
Maybe if we can get a pre-order of 10 or more Kelly might reconsider.
Or someone that knows him well enough might persuade him more than I.
