BMC Roadmachine ONE Disc Road Bike 2022
The carbon layup used for the frame and fork has been specifically developed for compliance as well as power transfer, so that multi-hour epic can be tackled in comfort whilst the bike’s geometry also has a slightly less aggressive position. However, power transfer from the bottom bracket area is still excellent, so no watts are wasted. This in-built comfort is complemented by the 33mm tyre clearance and D-shaped seatpost which also helps reduce fatiguing road vibrations.
Now semi-wireless, Shimano’s 12-speed Ultegra groupset connects the shifters to the derailleurs without any wires, which helps keep the front end of the bike tidy and allows native connectivity to smartphones and GPS computers. Effortless shifts are actuated by a light press of the appropriate lever, no matter how much pressure is being applied to the pedals and the gearing is ideal for long or hilly routes thanks to the 50/34 chainset and 11-34 cassette. Braking is just as easy as changing gear, with the Ultegra Servo Wave hydraulic disc brakes providing excellent power and control.
Mid-depth carbon wheels, the very discreet seatpost clamp and the Integrated Cockpit Design not only look very smart but also help the bike slip through the air more easily.
