BMC’s Fourstroke FS01 29 rides like its wheels barely touch the ground. The carbon frame is unnaturally lightweight; while stiff through-axles help you hold your line. A tapered, Kashima-coated Fox Float fork adds additional steering precision and provides 100mm of travel with nearly frictionless movement. A matching Fox shock complements the FS01’s APS suspension, creating an active, efficient ride. Carbon BMC wheels shred corners and lay waste to every climb in sight. The illustrious Shimano XTR drivetrain and brakes offer smooth, precise shifting and speed modulation. Plus, BMC spec'd the FS01 with their carbon seatpost, short stem, wide carbon bars, and a comfortable Fizik saddle.

BMC APS Suspension

BMC's Advanced Pivot System (APS) balances the applied forces of shock absorption and pedaling efficiency to maintain chain tension and rear wheel traction. BMC connected two laterally stiff triangles with a pair of links and an ideally located virtual pivot point (instant balance center noted in graphic). The result is outstanding traction, power transfer, and a ride ready for everything from XC to enduro.

BMC iSC Integrated Skeleton Concept

BMC's iSC (Integrated Skeleton Concept) saves weight by supporting the top tube at the seat tube, increasing stiffness where necessary: in the front triangle of the frame. Using the latest in FEM (Finite Elements Method) computer technology, they can tailor each tube junction for the appropriate distribution of forces.
