The 27.5-plus tire size finds a new home in the Spark 720 Plus series. Every advantage of the new Spark design is amplified in the Plus version. Thanks to a FOX 34 Float Factory Air fork with 130mm travel, a FOX NUDE rear shock and a dropper post, this bike is a good times machine.
27.5" Plus Technology
Mountain Biking never stands still. Standards are not written in stone as long as we are constantly improving what we love most: Mountain Biking. Wheel and tire sizes have always been and always will be a hot topic- we have seen this more than ever in the past three years. With the new Plus size, there is a new dimension emerging. Tire width has been underrated for too long. We are confident that the 27.5 Plus addition to the existing wheel size geometry standards will make its way into the mountain biker’s vision.
Twinlok Lever System
Scott's 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.
Asymmetric Design
The Spark down tube shock and linkage are clearly asymmetric, when looking from the top of the bike. Off setting the shock slightly to the left hand side of the bike gives a clean and continuous structure from the down tube through the shock mount to the main pivot.
Trunnion Construction
Scott have adopted the new Metric shock sizing standards with a Trunnion mount. Since the shock body now extends between the two lower mounting bolts, Scott's suspension partners have more design space. This means the shock has more stroke for the same eye to eye length. Stroke on the 165mm eye to eye shock has increased from 38mm to 40/45mm.The Trunnion standard also offers structural gains. The shorter shock enables Scott to build a very compact frame and shock package, which integrates tightly to the seat tube. Scott managed to have a very tiny yet stiff linkage-lighter than ever. Thanks to the Trunnion mount construction, stand over height on the new Spark is very low. Scott are still able to realize a super compact full suspension frame and provide the ability to mount both a small and big water bottle.
Boost Technology
Boost is a hub and drivetrain standard developed by SRAM. Boost is built around a wider rear and front hub and enables stiffer wheels due to a wider spoke bracing angle. Boost 148 rear hubs move each flange of the rear hub three millimeters wider.
Boost is designed as a complete system so drivetrain performance isn’t compromised. Even though Boost pushes the cogs three millimeters outboard, the crankarm Q-Factor remains the same as the Boost system’s crankset utilizes front chainrings that sit a corresponding 3mm outward to ensure the required chainline. Boost cranks can onlybe used when paired with a 148mm hub. On the front the hub spacing is increased by 10mm to 110mm. Increased wheel stiffness and greater clearance for bigger tires are the main advantages of Boost technology. On Scott's bikes, they wanted to go beyond the basics and reap all the benefits of this innovation by optimizing frame design and geometry.The 3 mm outboard chain ring adds clearance in the chain stay area that allows a substantial increase of the chain stay tube cross-section. Correspondingly,the stiffness in this part of the frame improves. Also, with a wider range of positions for the rear wheel, the frame geometry can be adjusted. Scott can shorten the chainstays for more agile handling.
