| Features | 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. Only available for Nude2 shocks on 2013 or previous year models.
Genius NUDE2 Shock: Dual Air Spring is the system used by SCOTT to attain two unique spring curves for TwinLoc and LTD (Lock-Trail-Descend) equipped bikes. Either a single air chamber or a combination of the two chambers allows for two unique geometry and travel modes within TwinLoc. When a smaller single chamber is used, there is less air volume and therefore the travel is shorter and the bike is less sagged, offering a steeper more agile bike geometry. When both chambers are employed, the air volume is increased allowing the bike to sag into a slacker position with more negative travel and more available travel at an engineered spring curve specifically for the full travel mode. The Nude2 shock is also considerably lighter than the Equalizer2 shock and the mounting position is more protected. Set-up is also easier due to a single positive air valve and more visible sag indication. Changing the shock mounting position also allowed us to run a steeper Seat Tube angle thus allowing riders who enjoy a more compact frame to run a longer post without affecting the relative Top Tube length.
27.5” Wheels: When discussing the pros and cons of the big wheeled bikes, shorter riders find themselves in an ambivalent situation. They want to benefit from the 29” wheels, but suffer from the negative effects when fit is considered. Additionally, the increase in rotational weight challenges many lower watt producing riders, so the performance gains are negated when the rider cannot accelerate the wheel system as quickly. The solution for many riders is 27,5”. The new wheelsize standard combines the best of both worlds, 29” and 26”.
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.
