I need a 28.6 seat clamp with no lip
I need it for the Decade Virtue build, in order to avoid the seat collar cracking problems, which was common on this mark of frame.
I have been advised by the very good people at Kinesis, to take 5mm off the seat collar and use a very long seat-tube.
They also suggest to either use a seat clamp that doesn’t have a lip, or get the lip on my existing “frame specific” Kinesis QR clamp milled down to suit.
However, before I go ahead and get the QR milled down, I was wondering if anyone here could recommend a seat clamp (size 28.6) that does NOT have a lip on the internal diameter?
To be honest, it doesn’t have to be a QR as long as it works

Cheers – They look the ticket.
Strange though – the ones listed at CRC and Wiggle all seem to have a lip on
Must be a different model 😕

AFAIK all seat collars invariably have a lip as this acts as a water barrier and to help correct seating of the clamp. I’ve certainly never seen one without. a lip.
… but here’s the answer! …
If you’re worried about cracking the frame, one of these should help as it takes lot of the tension from clamping the frame and places it on the pillar:-
I’ve still got one from my old MTB that’s long since departed – it works wonderfully well.

Thanks Steve, that looks the ticket

Trouble was – I couldn’t find one (New) for the size I needed
Went for one of these instead
A bit chunky (even for a double bolt) but they have no lip – plus they had gold – which fits my colour-scheme
Worth a punt at £7.49

That may well do it as it spreads to load.
Another small point is to use some carbon assembly paste as this again allows clamping with less torque.
I had a single-bolt Scott pin that let the saddle rotate at 20psi, a bit past the max. rec. of 17, A decent dollop of Tacx Carbon Assembly Paste (yes, even on alloy-to-alloy) held it at 14-15psi.
