The X-LAB RT9 Shadowbox frameset is the foundation for a lightweight road climbing build. You get the carbon frame, fork and seatpost, then choose the components that suit your riding and fit.
What you are building with
Toray T1100 + M40X carbon frame, compatible with a Universal Derailleur Hanger (UDH).
Toray T1100 carbon fork with a 100 × 12 mm front thru-axle interface.
27.2 mm carbon seatpost.
X-Lab lists 1.14 kg for the Medium frameset without headsets. Its approximately 550 g frame figure refers to the frame alone, not the complete frameset.
