FeaturesTwinloc Lever System: Our patented Twin Loc technology now offers simultaneous control of rear shock travel and fork lockout. The open position allows full travel, front and rear. One click switches the rear shock to Traction mode, while the fork remains fully active. Click again and rear shock and fork lock at the same time. No other bike in the world offers this user friendly system. Found on the Spark & Genius and Genius LT models. Only available for Nude2 shocks on 2013 or previous year models. NUDE2 Shock: The Nude2 is a completely new shock with an improved air spring and damping system. The shock possesses a more progressive damping curve and mode sensitive damping than its predecessor. This means that both travel modes have separate damper settings relative to their travel length and effective forces. When collecting data for the Spark project, we also calculated rider input data, including forces such as the rider’s gyro-scoping pedal stroke and its effects on the suspension. We simulated a rider’s pedaling and jerky motions made to clear obstacles, and measured their influence on the suspension. Many other designs assume that a rider is static and coasting, or they only include acceleration forces on the suspension and drivetrain. We are more concentrated on suspending the movement of the rider instead of negating pedaling forces. Adjustable BB Height: The Spark employs an adjustable geometry by way of a shock mount chip in the linkage. By changing the shock mount chip--simply removing it and flipping it in either mounting position--you affect the bottom bracket height by 7mm, which also affects the head tube angle by 0.5 degrees. The Spark is the only XC/Marathon bike on the market that offers this feature. Tapered Headtube: The Spark features a tapered head tube for increased stiffness, safety, confidence, and control. Direct Mount Post: We've saved even more weight by eliminating bulky brake hardware for mounting the rear caliper and integrated a direct post mount to the chain stay. This mounting position also decreases the load the brakes apply to the swingarm parts.
