BMC Roadmachine X AL Disc Road Bike 2022
Taking BMC’s Roadmachine concept and moving it further off-road, the Roadmachine X AL Disc Road Bike is happy munching away the miles whether on tarmac or gravel. The aluminium frame’s Gravel+ geometry has a lengthened wheelbase for stability and ease of handling on difficult terrain whilst still retaining the long-distance speed that the original bike was renowned for. Mounts for mudguards, a rack and other cargo increases its brief into the realms of bikepacking or commuting.
Shimano’s gravel-specific GRX groupset uses a 2x configuration that allows for a wide range of gears without the need for large jumps in the cassette, so finding the ideal cadence is easier whether on or off-road. The hydraulic disc brakes are equally adept when it comes to adding control and confidence in any weather conditions and the shallow rimmed wheels won’t be overwhelmed in blustery crosswinds. Supplied with versatile 32mm WTB Expanse tyres, the frame and fork have the capacity for rubber up to 45mm wide for true off-road performance.
