Велосипед BMC Fourstroke Two

BMC Fourstroke Two Mountain Bike | Arctic Silver — Black

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.

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.
