BMC's Fourstroke FS03 is ready for long days of fast single-track bliss. Its light aluminum frame dances up climbs, while the rear thru-axle and slack head tube promise a fun, controlled descent. A tapered Fox Float CTD fork offers precision steering and 120mm of trail-smoothing travel; plus, BMC’s APS suspension is paired with a Fox shock for 100mm of active, efficient rear travel. Stiff 29-inch Mavic wheels hold their speed and roll through everything, and the Continental tires are fast with impressive grip. Reliable Shimano Deore brakes keep you in control, while a smooth-shifting Shimano XT/SLX drivetrain easily transitions from spinning up steep inclines to blasting back down that fire road to the car and your buddy’s cooler. BMC also gives you a light aluminum seatpost, a short stem, and wide bars, as well as a comfortable Selle Royal saddle.
