Велосипед BMC TWOSTROKE 01 TWO

BMC Fourstroke 01 Two Mountain Bike | Carbon Black — Red

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

:

:

Fourstroke 01 is an XCO performance bike that exceeds the demands of the world’s top racers. On a mission to set the pace with our unique Autodrop technology and unrivalled APS dual-link suspension with 100mm of front and rear travel, it bests the competition in a Premium Carbon frame.

:

:

This revolutionized racing machine arrives with integrated protection and is designed around the progressive BWC geometry, now accommodating two water bottles in the front triangle for long-distance missions.

:

:

: The first ever fully integrated, automatic dropper post​

:

:

Every rider’s all-new secret weapon, BMC Autodrop provides the first ever fully integrated, automatic dropper post.

:

:

This revolutionary technology is featured on Fourstroke 01 and enables on-the-fly and squat-free seatpost dropping to push further faster.​

:

: When Every Second Matters

:

:

During a race, BMC riders activate Autodrop up to a hundred times allowing them to focus entirely on the track.

:

:

The peerless technology eliminates the need to squat to lower the saddle with it’s intuitive two-position adjustment, allowing riders to pedal longer before hitting a downhill section.

:

:

The result? More speed, improved lap times and less fatigue for a race-defining split-second advantage.

:

: Functionality

:

:

Mechanical operation

: Autodrop is a mechanically operated dropper seatpost enabled by the air tank housed in the downtube.

:

:

No batteries required

: The dropper seat post is actuated by a cable, while the Autodrop function is powered by pressurized air contained in the downtube air tank.

:

:

Pump it up!

: The air tank can be filled using a regular track pump. 14 bars allow for around 100 activations of the Autodrop system.

:

:

No range anxiety!

: Enough to win a World Cup event or day-long trail rides: when the air tank is empty, Autodrop still works like a regular dropper seatpost allowing your body weight to drop.

:

:

:

:

Intuitive

: Use it like a regular post: no learning curve is required.

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.
