We are delighted to announce the introduction of the new Fourstroke 01 on September 7th. Born to surpass the demands of the world’s top XC athletes, the Fourstroke 01 delivers the ultimate performance on the most demanding courses. Our holistic approach to look at the bike as an entire system allowed us to develop our fastest and most intuitive race bike ever.
RAD, the first integrated XC dropper seatpost
RAD (Race Application Dropper) is the world’s first integrated XC dropper post. A genius engineering solution driven by our athletes’ need for modern XC descending performance packed into a featherweight system. With an overall weight of only 345g, RAD shaves off more than 100g over a conventional dropper post design while delivering maximum descending and uphill performance with its intuitive two-position adjustment.
BWC Race Geometry, a new approach
BWC (Big Wheel Concept) Race is designed to attack the fastest, steepest and loosest XC courses with all the confidence of its 67.5˚ head angle and a long front-end. The 100mm travel fork with its 44mm offset ensures easy to handle steering on hairpins and technical sections. We updated the Fourstroke 01 with 429mm short chainstays to help you delivering power in the most efficient way with heaps of traction on the most technical sections. The steep 75.5˚ seat angle puts you in a more central position so you can attack steep sections with the perfect weight distribution.
Every gram counts
The Fourstroke 01 has been revised from the ground up with incredible attention to detail. Fewer parts extend reliability and durability of the system and improve overall weight, that allows the addition of a dropper seatpost and still achieve an extremely competitive system weight of 2575g (overall system weight including RAD seatpost and hardware).
Built for efficiency
Accept no compromises with a lightweight chassis designed for class-leading stiffness and lightning-fast sprints. The refined APS (Advanced Pivot System) suspension delivers pedaling efficiency, traction and control on every race course.
