BMC Roadmachine One Ultegra Di2 12-speed Sand 2026 road bike

This bike offers the perfect combination of long-distance comfort and performance on demanding roads. The BMC Roadmachine One 2026 features a carbon frame with Tuned Compliance Concept Endurance geometry and full cable integration via the ICS system, ensuring clean lines. Mounting points for mudguards, storage in the down tube and discreet fork dropouts enhance its practicality.

Ride with complete control thanks to the Shimano Ultegra Di2 12-speed electronic drivetrain, whilst the carbon fork, with a 12×100 mm thru-axle, optimises handling. The integrated cockpit (RSM 01 stem + HB D4 03 handlebar) improves aerodynamics and comfort. The carbon seatpost with a 15 mm setback offers precise adjustment, whilst the Selle Italia X Superflow saddle enhances support. An integrated rear light and a storage pouch complete this package designed for long endurance rides on the roads.
