BMC Fourstroke One Mountain Bike | Deep Purple - White

BMC Fourstroke One Mountain Bike | Deep Purple - White

Designed to dominate Cross-Country race courses, from World Cup level to your local series.

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.

Traction is Speed

More traction equals more speed, and that is what BMC is after.

The updated APS Suspension System features next-level kinematics and best-in-class suspension performance designed to deliver full traction and great efficiency on every terrain. Resulting in faster times, this new and improved full-feature suspension system finds no match on the race-course.

Advanced Pivot System – the best tool for the job

• Using APS, BMC engineers have access to a versatile suspension system with the ability to design complex kinematics that could not be achieved using weight-driven solutions like flex stays and single-pivot suspension systems.

• APS features a virtual rear suspension pivot trough the rear wheel travel, which is defined by upper and lower link and the resulting 4 pivots.

• APS allows BMC to fine-tune the suspension kinematics to provide an incredibly dynamic suspension behavior across the travel.

Uphill Traction:

The anti-squat tuning featured on Fourstroke decreases along the travel, preventing chain growth when hitting obstacles; this allows the suspension to compress smoothly and track the terrain for perfect traction.

Once the suspension starts extending again, the anti-squat value rises to keep the wheel tracking the terrain, significantly increasing the grip.

Downhill Flow:

APS keeps the suspension active when the going gets tough by reducing pedal-kickback deep in the travel and preventing negative influences during braking.

Improved Suspension Progressivity:

The updated Fourstroke kinematics and all-new shock tune provide a progressive spring curve, delivering a superior ride experience in any riding situation.

• Small bump sensitivity

• Support in rough conditions

• Bottomless feeling

• More predictable airtime behavior

The Winning Edge

Extensive testing shows that the Fourstroke and APS suspension are faster than lighter bikes that feature weight-saving suspension systems, proving that superior traction and pedaling efficiency are more important than weight.
