[#9723518]

Slowly building up a classic (i.e. 27.2" seat tube) Soul.

Received wisdom (i.e. what I read on CRC) is that for a 27.2" frame, the OD for a clamp is 28.6". That's [url= https://www.cotic.co.uk/product/classic_soul ]backed up by the Cotic page on the classic Soul.[/url]

Got a 28.6" clamp. Doesn't fit.

Duff clamp? me being a numpty? something else?

It says the f/mech size is 28.6mm, not the seat clamp.

29.8/30mm would be my guess. Easiest to jut measure it though.

Yes, but a straight seat tube I would have assumed that the OD of the tube is the same down at the mech end as it is at the seat post end? 😕

It's not a straight tube though is it! Just look at it or measure it, it'll be tapered. 28.6mm seat clamps with a 27.2mm seat post is a pretty lightweight tube, I don't think strong enough for an MTB that runs alot of exposed seatpost.

Don't use a hope clamp is my advice, could never stop mine slipping on my MK1 Soul.

Salsa fliplock was ace.

Mine too, shortly! Sorry, only trying to distinguish it from the dropper-friendly and latterly tapered headtube frames (oh, and start establishing it as a niche retro find coveted by hipsters in years to come 😀 )

30.0mm as others have said. I have a Hope qr clamp on mine and did slip at first but I tweaked up the barrel nut until tight then the lever and have never had a problem since.
