Radcity seatpost clamp size

[cudacarlos]

I want to get rid of the quick release seatpost clamp and replace it with something more secure. Does any one happen to know what size clamp would work? I don't have calipers to measure the seatpost tube myself and can't find it on the radcity spec sheet. Thanks.

The seat post is 27.2 mm

Thanks. I’m actually looking for the seatpost tube measurement though. The tube that the clamp wraps around.

Borrowed a set of calipers from a friend and measured myself. It's 30 mm.

I just unscrewed the quick release lever and replace with a locking nut. Easy breezy. 20c at Ace hardware

I replaced mine with a 31.8mm clamp and it works perfectly.
