Item: #MF083126 – Carbon Road Ultra Lite Frame+Fork Set | Pre-Production Sample (Size 52cm, Excellent Condition)
Rating: Excellent Condition
A rare pre-production Carbon Road Ultra Lite frameset from State Bicycle Co. This is not the 2026 Aero Carbon Road model. This earlier prototype features a more relaxed, endurance-leaning geometry, traditional non-internal cockpit routing, and a non-UDH derailleur interface.
The standout feature is the exceptionally light carbon chassis, with the bare frame weighing under 800g without hardware. Previously owned, ridden, and professionally maintained by SBC staff, this frameset remains in excellent overall condition and is the foundation for an exceptionally lightweight road build.
With the right component selection, this frameset is capable of serving as the bones of a sub-14.5 lb complete bike.
