BMC Roadmachine X ONE Disc Road Bike
The frame shares its geometry with its successful Roadmachine sibling and uses the same Tuned Compliance Concept Endurance carbon layup that balances comfort and efficiency, making it a formidable long-distance partner. The relatively short chainstays give a nimble and responsive feel whilst the longer front end imbues confidence on any surface.
When riding rougher tracks, the Redshift Suspension stem gives improved control, greater comfort and less fatigue, as two elastomers provide a modicum of travel giving the bike a plush feel. These elastomers can be switched out to fine-tune the suspension to rider style, weight and terrain. The carbon seatpost is also Roadmachine X specific, with its layup and D-shape adding extra compliance to the rear of the bike when seated.
Also blending road and off-road requirements, the SRAM eTap AXS groupset borrows elements from their Force and XPLR ranges, making up a fully wireless drivetrain with a very wide range cassette, single ring crankset and hydraulic disc brakes. This allows the bike to perform just as well on the trails as it does on the tarmac. As with all AXS groupsets, the system can be connected to compatible GPS devices and smartphones for extra information and customisation.
32mm wide WTB Expanse tyres are paired with CRD-321 carbon wheels to continue the versatile theme and work across a wide range of surfaces with a fast-rolling centre section and lightly treaded shoulders. As both are tubeless ready they can be run with lower pressures without fear of pinch punctures and for the extra benefits of more grip and comfort.
