BMC Roadmachine One road bike Shimano Ultegra Di2 12-speed Black Carbon 2027

The Roadmachine One in Black Carbon embodies modern endurance in its most refined form. Its understated appearance belies a bike designed for long rides, whatever the conditions. Whether it’s light rain, uneven tarmac or long, fast-paced rides, it remains stable, smooth and reassuring.

Its Advanced Carbon frame, developed by BMC, prioritises intelligent comfort without ever compromising on a dynamic ride feel. It absorbs vibrations when the road surface deteriorates, whilst maintaining precise handling and excellent efficiency when you pick up the pace.

The Shimano Ultegra Di2 12-speed drivetrain ensures crisp and consistent gear changes, perfect for maintaining a steady cadence over long distances. The tubeless-ready AR 27 wheels and 32 mm wide tyres provide grip and smoothness, reinforcing that sense of constant control.

Add the integrated storage in the down tube, the rear light and mudguard compatibility, and you have a true ‘do-it-all’ bike: high-performing, comfortable and ready for both big days out and everyday rides.
