Every second matters
The rulebook has been thrown away: re-imagine the ultimate XC race bike and join the revolution - where up meets down.
Born to surpass the demands of the world’s top XC athletes, the Fourstroke 01 delivers the ultimate performance on the most demanding courses.
A purpose-designed race machine, every element of its structure is crafted to optimize speed, save seconds, and keep riders ahead of the pack.
Our all-new Race Application Dropper Seatpost (RAD) ensures that its fast and smooth adjustments maximize power and control whatever the gradient, allowing you to ride more dynamically. The revised Big Wheel Concept Race (BWC) geometry has evolved to embody the progressive riding style our athletes display on technical World Cup tracks.
The Fourstroke 01 shifts the paradigm. Reel in the competition on the climbs, drop them on the descents. Every second matters.
Fourstroke 01 Hotspots
Every gram counts
Light and Efficient
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.
Integrated headset cups provide weight savings of 20g vs. external ones and improve reliability
The all-new carbon upper link provides the stiffest connection between front triangle and swingarm for uncompromised suspension performance and weight savings of 40g
The optimized suspension hardware reduces the number of parts for improved reliability and weight savings of 51g compared to the previous Fourstroke 01
The super-light thru-axle developed in the Impec Lab saves additional 9g
- Frame weight with shock: 2180g
- Overall system weight including RAD seatpost and hardware: 2525g
- Complete bike weight: 10kg
Built for efficiency
Put the hammer down!
The Fourstroke 01 is designed for unparalleled power delivery with a redesigned chassis that excels in torsional and bottom bracket stiffness. A true performance leap that boosts one of the most successful XC race bikes on the scene to a new level.
