Thought about the bolt, but wasn;t sure it would be strong enough and didn't want to break anything trying.

If memory serves me the Team Triumph bike from 2005 had an alloy block welded to the fork leg itself. This slotted into the channel on the brake drum and worked a treat.

Well it worked better then their engine anyway.

I'm not a good enough welder to do it myself, so we found another solution for the TRB bike. Find a local wheel builder and get the C90 rim fitted to the CB100 hub, same number of spokes. It cost us £45 and means we have a disc brake on the front.
