Campagnolo 10-speed Carbon Ultra Torque Chainset - 170-172.5mm

Hello.
As the title says, I'm after a Campagnolo Ultra torque carbon chainset 10sp (although I think 11 will also work with the 10 speed chain won't it)

• with chainrings - 53/39 is fine, but smaller is marginally better for me.
  Not bothered if it's centaur, chorus or record to be honest. I'll probaby sand off the text and re-clearcoat anyway.
  170 or 172.5mm length please.
  Doesn't have to be mint really, so cheaper is better.
  If you can post please.
  Thanks
