BMC Fourstroke 01 One Mountain Bike | Turquoise - Black

BMC Fourstroke 01 One Mountain Bike | Turquoise - Black

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.

Fourstroke 01 LTD is your all-new secret weapon and arrives with a SRAM XX1 Eagle AXS drivetrain, Fox Float 32 SC Factory fork and Fox Float DPS Factory shock, DT Swiss XRC 1200 wheels and the BMC Autodrop integrated dropper seatpost.

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.
