This is a 2014 LaPierre Xelius EFI 600 Frameset in size 58 or XL on the geometry chart. It's an extremely light carbon frameset, weighing in at 4lbs / 1.8kg as photo'ed. The bike came as a Shimano Di2 bike, so is currently set up for electronic shifting, but does also include all of the frame hardware to use mechanical shifting.

Tapered Steer tube, 1 1/4 to 1 1/8"
8cm of steer tube above the top of the headtube
BB86 press fit bottom bracket
Braze on Front Derailleur mount
31.6mm seatpost (Ritchey Carbon Pro included in Auction)

We ran tubes through the frame when we disassembled to make running wires/cables easier on reassembly.
