Technology Direct Post Mount Scott 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. Tapered Headtube The Spark features a tapered head tube for increased stiffness, safety, confidence, and control. 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. IDS SL Dropout System Interchangeable and lightweight, the IDS-SL dropout system works with 142x12mm, 135x12mm and 135x5mm QR rear axle standards. Shred the turns more aggressively and with enhanced control, because the rear end is laterally stiff. Rock Shox DNA3 System A brand new feature and the collaboration of SCOTT and RockShox is the DNA3 system. This allows the extension of TwinLoc’s three unique shock modes to the fork. Previously, the TwinLoc controlled the travel settings only of the shock, with the ability to lockout both the shock and fork. Now with the remote TwinLoc lever, you can not only lock shock and fork, both you can also control the traction mode or full mode of both shock and fork with a simple flick of the switch. The Spark is the only bike on the market that offers this adjustment and it comes on all models, 26” and 29”, that are equipped with the Nude2 shock. Carbon Swingarm and Dropouts On the carbon swingarms and dropouts they used Scott’s IMP5 carbon technology just like with the mainframe.This guarantees a high stiffness and lightweight in the rear part of the bike. IMP5™ Carbon Mainframe The Spark frame is built using Scott's IMP5 carbon technology. This means that five parts of the main frame are produced in one single step, in this case the head tube, top tube, seat tube, down tube, and bottom bracket structure all joined in one step while carefully managing the layers for quality and effective use of material. Both HMX and HMF fibers are used in their carbon frames ensuring the utmost durability, security, and longevity for the frame. 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, Scott also calculated rider input data, including forces such as the rider’s gyro-scoping pedal stroke and its’ effects on the suspension. Scott 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. They are more concentrated on suspending the movement of the rider instead of negating pedaling forces.
