Thanks - yes the custom spacer is a tight sliding fit on the Gusset ring, to get it all to line up - 7 pins in the drive flange and 6 holes in the ring + the freewheel can rotate with the Gusset spacer fixed to it - we had to find a spot where it all lined up - we used centre punch marks that line up to show the 'sweet spot'. the 7 pins were a tight fit in the custom ring (and loctited in) and were just a few thou' undersized to ensure they located in the flange easily. The 6 grub screws are just undersized for the holes in the Gusset ring but bottom out on the freewheel body. There is no discernible play in the system - it is locked up solid as the Gusset cassette lock ring pushes the whole lot onto the freewheel body and then the custom ring on to the hub face. I have had a couple of rides now and it works really well and the Shamal wheels are really fast.
