Optimized APS Suspension
More traction equals more speed and that is what we are after. Next-level kinematics tuning, and best-in-class suspension performance delivers full traction, great efficiency, and active suspension on every terrain. Resulting in faster times, this new and improved full-feature suspension allows you to pedal efficiently, brake hard, and charge rough terrain without compromise.
Redefined Geometry
BWC Race is tailored to a fast and progressive racing style designed to attack the steepest and loosest courses with the improved 66.5° head angle and a long front-end. The 429mm short chainstays deliver power with proven traction on the most technical sections. The lowered bottom bracket and a steep 76.7° seat angle provide perfect weight distribution and handling.
Go Long
The Fourstroke LT is versatile by design to let you carry speed with confidence on technical trails. It has been optimized to fit two water bottles and arrives with 120 mm of suspension travel to push the trail boundaries with 34 to 35 mm forks and a 62 mm tire clearance to fit 2.4″ Maxxis Rekon tires with EXO protection.
Dropper Post
Fourstroke LT features a standard seat tube that allows the use of classic 31.6mm dropper posts for extended versatility and optimization.
Design Boost
Put the hammer down! The redesigned chassis excels in torsional and pedalling stiffness for unparalleled power delivery. A true performance leap that boosts one of the most successful Cross-Country bikes on the scene to a new level.
User-Friendly Protection
The internal cable routing on Fourstroke LT is completely guided through front triangle, lower link, and rear triangle, making service intervals a breeze. An integrated fork stopper, chainstay protector and the lower link mud flap protects the frame for improved durability.
