BMC Roadmachine FOUR Disc Road Bike Rival AXS 2022
The BMC Roadmachine FOUR Rival AXS is a do-it-all performance disc road bike that blends comfort with speed for all-day rides and events. Compliance-boosting TCC (Tuned Compliance Concept) Endurance reduces fatigue and improves control over even the roughest roads so you can ride harder for longer, while the D-shaped carbon seatpost further soaks up shock.
SRAM's wireless electronic Rival eTap AXS components take care of shifting and braking, delivering smooth, reliable changes at the touch of a button, alongside confidence-inspiring stopping power in all conditions. The SRAM AXS app allows the customisation of functionality to suit personal requirements.
BMC XR-522 tubeless-ready disc wheels are paired with Vittoria Rubino tyres in a wide 28mm configuration for smoother, faster rolling. Brake cables are all routed internally to deliver a sleek, clean aesthetic.
