Dan, I managed to find the instructions to adjust the surge brake but so far none of the parts listings have lined up. I tried both the UK and German Knott websites. I'll PM the Blanik USA guy to see if he's got what I'm looking for. I'd like to replace the sealed bearings and get replacement nuts for both hubs. They are torque once, do not reuse.

If you find a manual with those part numbers it would be a huge help.
