Get ready to meet the next generation of Cross-Country bikes. Whether you are an ambitious racer, or on the hunt for that downhill rush, the Fourstroke family has you covered.
This is your go to machine for absolute commitment and ultimate performance. Designed to push the boundaries of XC riding with limitless confidence on every course. From World Cup level to your local trail.
Autodrop Technology
The secret weapon exclusive to the Fourstroke 01 series. The first ever fully integrated, automatic dropper post for on-the-fly and squat-free seatpost dropping to push further, faster, and on even the most technical XC courses. With an intuitive two-position adjustment our lightweight Autodrop technology gives every rider the race-defining split-second medal-winning advantage.
Redefined Capabilities
The entire Fourstroke family features the redefined APS and BWC Race capabilities.
More traction, more speed. The updated Advanced Pivot Suspension System features next-level kinematics and best-in-class suspension performance designed to deliver full traction and great efficiency on all terrain. Resulting in faster times, this new and improved full-feature suspension system finds no match on the course.
The next evolution of Big Wheel Concept Race technology pushes the XC collections’ capabilities further. Progressive refinements improve the rider position for better power transfer and traction on steep terrain, while equally expanding your descending capabilities and providing perfect weight distribution for incredible handling.
Design Boost
These medal-winning marathon machines are versatile by design. Allowing you to go far, all models have been redesigned to accommodate two water bottles on side-entry bottle cages in the main triangle without compromising performance and functionality.
