Fourstroke is the cornerstone Cross-Country bike designed to excel on every level. Offering beyond-the-tape versatility, this XC machine is setting a new standard with unrivalled 100mm APS dual-link suspension travel. The redefined Big Wheel Concept geometry improves performance in a lightweight full-carbon frame with integrated protection and two water bottle cages for long-distance rides. The Fourstroke ONE is designed to dominate with the SRAM Gx Eagle AXS drivetrain, RockShox SID SL Select+ fork and RockShox SIDLuxe Select+ shock, DT Swiss XR 1700 wheelset with 25mm inner width, and the Bikeyoke Divine seatpost.
