The Factor Ostro VAM V2 is designed to be both lightweight and aerodynamic — a combination most bikes used to compromise on. I found this frame in almost new condition and built it up exactly the way I wanted.
The build runs a mixed Shimano Ultegra/Dura-Ace Di2 12-speed groupset, a Quarq DFour power meter crankset, and BTLos Aerix Pro 52mm wheels with DT 350 hubs and Sapim CX-Ray spokes — coming in at around 1290 grams for the set. One detail I’m particularly happy with: a custom ASA 3D printed headset spacer I designed to match the Tavelo Avro integrated bar and stem setup.
The complete build came in at 16 lbs 3 oz for a size 54 — solid for an aero platform.
