BWC Geometry

The demands of cross country mountain bike racing require a maneuverable machine that inspires confidence when you scream down the final descent into a sprint finish. A long top tube, slack head tube angle and a wide bar paired with short stem and chainstays is our recipe for making big wheels roll fast and turn easily. The entire Fourstroke family is built around this super progressive approach to bike geometry.

Lightweight

Chasing the podiums of World Cup races is all about maximizing technical advantages. A frame that weighs merely 2.5 kilos is a fantastic place to start. Advancements in carbon technology combined with the skill of our Impec Lab’s engineers resulted in an industry and race-leading machine for XC and Marathon mountain bike racing.

Efficient

Our Advanced Pivot System (APS) for the Fourstroke family focuses on efficiency and reducing rider fatigue. APS’s high tech design promotes extreme pedaling efficiency. How extreme? World Champion extreme. Thanks to the efficiency of APS, the Fourstroke is one of the only full-suspension bikes in the world to have won the XCO World Championships.
