I've been searching for for a lipless 28.6mm seatclamp for a while, so I can use the Sheldon Brown style of aheadset adjustment, i.e seatclamp holds everything in place. See here.

After scouring the UK and actually asking people to measure said seatclamps, I still can't find one without a lip that's actually the right size.

Does anyone have one sitting at the bottom of a box somewhere not seeing any use, project is at a bit of a standstill without it.

Cheers .
