• Fourstroke R 01 frameset with 120mm APS suspension, Autodrop seatpost. Fitted with only the best: Öhlins suspension, SRAM XX SL Eagle and DT Swiss XRC 1200.

Purpose-built for podium chasers, the Fourstroke 01 brings together cutting-edge BMC design and uncompromising Impec Lab engineered performance. At its core is BMC's APS suspension kinematics and the ultra-efficient Autodrop integrated dropper seatpost, delivering efficiency and speed on any terrain. Its Premium Carbon frame is optimized for modern XC racing thanks to a progressive geometry, and its 120mm of front and rear travel. New this year, the ICS Carbon XC one-piece cockpit gives you additional control and confidence thanks to a design flex and compliance. Outfitted with a SRAM XX SL AXS Eagle Transmission, suspension relying on Öhlins RXC34 Carbon fork, and Öhlins TXC2 Air shock, as well as spinning the trusted and light DT Swiss XRC 1200 wheels, it's a bike ready to race from the first ride.
