2013 BMC Fourstroke FS01 29 XTR – First Look

BMC Fourstroke FS01 29 is the top bike in BMC’s new 29er full-sus lineup. As the name implies, the Fourstroke FS01 29 has 4in (100mm) of suspension travel. The frame with rear shock and associated hardware weighs 2,040g (4.5lb). The Fourstroke series is designed with endurance/marathon racing in mind, but as the video below shows, it looks to be a capable short-travel trail bike as well.

Race ready, trail proven, all-mountain capable

The BMC fourstroke FS01 is our most capable and diverse mountain bike. It’s so versatile, it’s hard to pin down its true nature. As one of the lightest all-carbon, full-suspension frames available it’s primed to line up at the start of any cross-country race. Yet, with its short chain stays and slack head tube angle, it’s equally adept at making

the most rugged trail feel like a Swiss autobahn. BMC’s legendary APS suspension and Big Wheel Concept geometry mean complete control, giving the rider absolute confidence at high speed, or in tricky technical situations. If you’re looking for one mountain bike that can do it all, look no further than the BMC fourstroke FS01.

Technology BMC Fourstroke :

  •  APS (Advanced Pivot System)The ideal suspension system converts all of a rider’s energy into forward propulsion, while at the same time absorbing impacts. Mechanically, these two goals are at odds with one another. But BMC’s APS rear suspension satisfies these two goals by carefully calculating the pivot points of the rear suspension so that inertial force generated under acceleration is not misdirected into compressing the shock.

    How is this accomplished? With APS the virtual pivot point is positioned so that constant chain tension is maintained for forward acceleration. As such, pedaling forces are used for forward propulsion with no loss of energy transfer in the suspension system. At the same time, the shock system ensures optimum rear wheel traction, guaranteeing that those pedaling forces are not only getting to the rear wheel, but to the ground, as well. The end result is a suspension system that provides extreme power transfer efficiency, uncanny traction, and excellent comfort.

  •  System IntegrationDirect assembly of the brake caliper to the frame with no need for an adapter means improved braking power transfer, especially under demanding conditions.
  • Initial Load Indicator
    Just set the sag adjustment according to the indicator, and go. Trailside adjustments have never been simpler.
