When uncompromising cross country performance is your single focus, BMC's Fourstroke 01 exceeds your needs. The carbon frame smashes preconceived notions with its shockingly low weight, paired with the stiffness and efficiency hold your line and launch you forward with every twitch. Delivering traction, control, and mind-melting speed is a Fox Float iCTD shock controlling the Fourstroke’s 100mm travel APS rear suspension. That shock, and the 100mm Fox 32 Float iCTD fork, feature Fox's ingenious bar-mounted electronic remote that lets you dial the suspension between Climb, Trail, and Descend modes with an effortless thumb click. Having your suspension in the ideal mode all the time makes winning the holeshot, smashing the climbs, and dusting riders on technical downhills a whole lot easier.
It keeps going; the specs are equally as focused. Shimano's XTR Di2 2x11 drivetrain is on board for telepathically quick and electronically perfect shifting. Carbon comprises the slingshot fast, 29-inch BMC wheels spun with DT Swiss hubs and wrapped in XC-specific Continental rubber. Genre-defining XTR discs haul this stealthy rocket back to reality, while more carbon crafts the handlebar and seatpost. Simply put, the BMC Fourstroke 01's single focus is the same as yours.
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.
