BMC's versatile Fourstroke FS01 Trailcrew is a purebred singletrack assassin whether you’re using it as a trail bike or XC race machine. The carbon frame keeps the weight down so you’re still fresh when you get to the top; meanwhile, a slack head tube and through-axles make it clear that this bike loves to shred. A tapered Fox CTD fork ensures dialed handling and 120mm of supple travel, and the matching Fox shock is paired with BMC’s APS suspension for an active, efficient rear end. DT Swiss hubs offer instant engagement and the 29-inch hoops are light and fast. A SRAM XX1 drivetrain with XO brakes delivers crisp shifting with minimal weight. And in the spirit of riding through anything, the Trailcrew is spec’d with a Reverb Stealth dropper post, BMC’s short stem, wide bars, and a comfortable Fizik saddle.
