Well, everything else is made from carbon these days, so why not your pump too? It'll take you a fair bit of effort to get up to 100psi with the Carbon Road but it's still a robustly made and well thought out model.
The handle and barrel are carbon, the shaft aluminium. The result is that the Airtool doesn't heat up like some other mini pumps. It's good to see a locking head, and one neat touch is that if you twist the top of the handle you'll find some glueless patches within. Clever.
