top work! so the custom ring slides over the gusset spacer? is there no play at all in the system? like from the pins being slightly smaller than the flange holes or the grub screws smaller than the gusset spacer holes.

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.
