The 2021 BMC Fourstroke 01 is a purpose-built cross-country race machine that doesn’t just chase podiums—it’s engineered for them. With 100mm of front and rear travel, BMC’s APS dual-link suspension system delivers efficient pedaling and active traction across rough, technical terrain. What really sets it apart is the Integrated Dropper Seatpost—BMC’s AutoDrop system—that allows for instant post lowering without manual input, a first in XC design. Its carbon frame geometry leans progressive, offering stability on descents without dulling the bike’s sharp climbing manners. Light, stiff, and uncompromising, the Fourstroke 01 is for riders who take racing seriously—and expect their bike to do the same.
