Details

BMC’s Fourstroke 01 is ultra-fast, ultra-light, and ready to annihilate cross country courses. The carbon frame, stiff through-axles, and APS rear suspension achieve an impressively lightweight, efficient ride with dialed control. Leading the path to victory, a Fox Float 32 Factory fork dials up precision steering while providing 100mm of buttery-smooth, Kashima-coated travel. A Kashima-coated Fox shock complements the APS suspension, creating an active, efficient 100mm travel rear end. And both the front and rear have remote lockouts when it's really time to put the hammer down. Putting your power down is SRAM’s quick XX1 1x11-speed drivetrain reeled in by XTR brakes with their incredible modulation and minimal weight. You’ll experience quick engagement, and the stiffness and response to drop the riders behind you with the DT Swiss XR 1501 Spline One wheels. BMC rounds out the spec with their carbon bars, carbon seatpost, 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.
