Details

Unleash pure cross country speed with BMC's Fourstroke 02. The frame's carbon front triangle, aluminum rear end, and stiff thru-axles achieve an impressive combination of minimal weight, strength, and control. A remote-controlled Fox Float 32 fork adds to the XC capabilities of the frame while providing 100mm of supple travel. The matching Fox shock is paired with BMC’s APS suspension for an active, efficient 100mm rear end. It all rolls on 29-inch DT Swiss wheels that are light, fast and stable—helpful when you’re pushing the pace on that final, exhausting descent. Shimano's XT drivetrain with matching disc brakes offers precision shifting and incredible braking modulation. BMC rounds out the spec with their stem, 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.
