2019 BMC Fourstroke 01 ONE XX1
Every second matters
The rulebook has been thrown away: re-imagine the ultimate XC race bike and join the revolution – where up meets down. Born to surpass the demands of the world’s top XC athletes, the Fourstroke 01 delivers the ultimate performance on the most demanding courses. A purpose-designed race machine, every element of its structure is crafted to optimize speed, save seconds, and keep riders ahead of the pack. Our all-new Race Application Dropper Seatpost (RAD) ensures that its fast and smooth adjustments maximize power and control whatever the gradient, allowing you to ride more dynamically. The revised Big Wheel Concept Race (BWC) geometry has evolved to embody the progressive riding style our athletes display on technical World Cup tracks. The Fourstroke 01 shifts the paradigm. Reel in the competition on the climbs, drop them on the descents. Every second matters.
