When race engineering meets full-gas fun, you get the Fourstroke R 01, our lightest full-suspension mountain bike frameset. Engineered in our Impec Lab and sharpened on the race circuit, this 01 Premium Carbon frameset floats up the climbs while progressive XC race geometry encourages you to charge downhill. But the real dark magic? APS suspension pivots tuned for maximum traction, paired with the ultra-efficient Autodrop integrated dropper seatpost. This frame-only variant comes ready for your dream XCO build. It includes the fully tunable Öhlins TXC2 Air rear shock. Now go crush it.

Technology

Redefined Geometry

BMC Race Geometry is engineered for racing on rough and technical courses. Tuned to handle the steepest, loosest terrain with confidence. The 66.5° head angle and extended reach add stability and control.

Optimized APS Suspension

Adjusting suspension pivots boosts efficiency. The secret is in their placement, optimized for real riding performance. Designed in our Impec Lab and proven on the race track. Trust us: it’s easier to feel the speed than explain the magic.

Go Long

Go the distance with an XC frame engineered to take two full-size bottles and still clear 62 mm (2.4”) tires, a rarity for a platform this aggressive. And don’t take our word for it: its palmarès already proves the design works.
