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.
Carbon Swingarm and Dropouts
On the carbon swingarms and dropouts, we used Scott's IMP5 carbon technology--just like with the mainframe. This provides stiffness and lightness in the rear of the bike.
Rock Shox DNA3 System
SCOTT and RockShox collaborated to bring you an all-new feature: the DNA3 system. DNA3 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. The remote TwinLoc lever allows you to not only lock shock and fork, but 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.
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, thanks to a laterally stiff rear end.
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.
The Spark features a tapered head tube for increased stiffness, safety, confidence, and control.
Direct Post Mount
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.
Twinloc 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.
IMP Carbon Mainframe
Our engineers have developed IMP™, the newest technology applied to carbon production. Our proprietary process allows for lighter construction by removing 11% of the material from the headtube intersection while increasing strength by utilizing high modulus stressed fibers for more precise fiber placement in critical areas. To compliment the IMP™ process, our frames benefit from our Naked External Tubeset™ which eliminates the cosmetic carbon layer to shave precious grams. Both HMX and HMF fibers are used in our carbon frames ensuring the utmost durability, security, and longevity for the frame."
