Raleigh aluminum TT frameset (includes aero kalloy alloy seat post not shown in picture) with Easton Aero full carbon fork. Bought new several years ago and never built.

Toptube is 52cm center to center.
Seat-tube is 49cm center to top.

The seatpost clamp is missing and I believe one from the Fuji aluminum aero frame can be used as a replacement, though I have not sourced and tried one.

This is frame, fork and seatpost only. No other parts are included.
