Please select options


Cross country, marathon, and singletrack riding has met its match 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. Up front, a Fox Float 32 fork adds to the high-end XC ride of the Fourstroke 02 while providing 100mm of supple travel. The matching Fox shock is paired with BMC’s APS suspension for an active, efficient 100mm of travel out back. 29-inch DT Swiss wheels are on rolling duty with light, fast and stable action—helpful when you’re pushing the pace on that final, exhausting descent. A Shimano SLX/XT drivetrain with SLX discs 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.
