Does a bike with an alloy seat post and a carbon frame need a seat post clamp with two bolts? Most clamps these days seem to be either quick release or single bolt. Is that safe to use with my set up?

I have read a little around the subject and not found any definitive answer.

giant seat clamp and bolt

On carbon frames I've used, they have had a single bolt clamp like this one, so it should be fine. Personally, I'd like to use a slightly bigger clamp and one of those rubber size-decreasing rings to avoid cracking the frame. If in doubt I'd phone up the manufacturer of the frame and ask!
