Can someone tell me what size I need please? I know it comes with a Hope QR but based on previous experience I'm not a fan so would rather spec my own.

Thank you kindly 😉

I agree, mine slipped. Just removed mine and replaced with fixed bolt. 27.2 seatpost and believe I used a Salsa.

30mm Salsa job done! Or one of the spank ones.

Well, I knew I'd get a quick reply, but that's beyond the call of duty, thanks!

Cotic do say it's a 27.2 seatpost on the site but I wasn't sure what outside diameter that would equate to for the clamp – 30mm it is then. And yes, I have a Salsa on the current bike and it's by far the best of the several clamps I've tried.

I'm waiting for the chromag one to be back in stock at CRC. They do look the dogs

Salsa was recommended to me, think I used it on the Juliana which has now been replaced with a Soul. I can't get on with QR clamps!

Agree with Chucky – those Chromag ones are really bling 8)
