Improved roll-over is the most noticeable attribute when it comes to 29” wheels. The big wheels are great for rolling over nasty roots and rocky sections, essentially making it easier to ride these conditions. Improved traction is also a key factor with the increased wheel diameter compared to 26” wheels as tire contact to the ground is larger.

• Best Roll-Over Performance

• Carries Momentum

• Maximum Traction surface

• Best stability on easy trails

• Lowest suspension stress

• Great for larger frame sizes

• Increase stability on long curve



While SCOTT already use the proven HMF composite fiber on all our composite high-end bike models, they have improved upon conventional HMF material. This new fiber, which is produced exclusively for SCOTT, offers 20% more stiffness and is employed on all the areas that need additional rigidity. This new material also allows us to reduce weight and improve riding characteristics. NET stands for Naked External Tubeset, where the frame sheds its exterior cosmetic layer, which saves even more weight.



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.



The Spark down tube shock and linkage are clearly asymmetric, when looking from the top of the bike. Carbon fibres achieve their full potential when used in smooth straight lines. 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.



SCOTT has adopted the new Metric shock sizing standards with a Trunnion mount. Since the shock body now extends between the two lower mounting bolts, their 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 to build a very compact frame and shock package, which integrates tightly to the seat tube. SCOTT’S 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 is still able to realize a super compact full suspension frame and provide the ability to mount both a small and big water bottle.

The Spark family maintains the 165mm eye-to-eye shock length of the previous Spark 900 (our shortest shock), but realises up to 7mm more shock stroke. All Spark RC and most Spark and Spark Plus bikes utilize the FOX Nude shock, specially made for SCOTT:

-165mm Metric Trunnion shock

-40mm (100mm travel RC Spark line-up) vs. 38mm (old Spark)

-45mm (120mm travel Spark line-up)

By turning the Trunnion shock upside-down, SCOTT can fully integrate it into the frame which results in several benefits. Since the Trunnion mount is the same width as the down tube and mainpivot, you can have a very clean frame design in this critical area. The lack of tight transitions and small details allows for an efficient, continuous carbon structure. Carbon material added to reinforce the shock mount also stiffens the connection between the down tube, main pivot and bottom bracket, a key stiffness path.

The flipped shock also lowers the frame’s center of gravity helping to give a more planted feel when riding. Unsprung mass is reduced since it is the lighter part of the shock, connected to the linkage, not the heavier body which must move during an impact – the suspension system can react faster. SCOTT’S TwinLoc remote cable can be routed cleanly into the down tube.



The Spark carbon linkage is constructed with a compression moulding process. It’s 37g lighter than the aluminium equivalent and half the weight of the previous Spark linkage. Making the link in two pieces means all excess material can be removed from the inside of the linkage, without sacrificing stiffness.



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.



Working together with DT Swiss, SCOTT’S completely revisited the shape of the thru-axle lever to make it more ergonomic and to perfectly fit to SCOTT’S frame. Additionally they introduce a new multifunctional tool integrated on the inner part of the thru-axle itself. This 25T torx wrench is easy to reach and ready to be used for quick adjustments on the trails.



SCOTT’S integrated chain guide was developed in collaboration with the SCOTT ODLO MTB Racing Team.

The idea behind was to create a reliable component that helps to avoid dropping chains but that was light, versatile and integrated in the design of the frame. The new Spark chain guide weighs just 23 grams and is easy to assemble thanks to the smart assembly system and can accommodate chain rings from 30 to 36 teeth.



With the proper selection of materials, eighty percent of the work to create a frame is done. But the remaining twenty percent requires most of the efforts. For this reason, SCOTT’S choice of the most advanced carbon fibers in the market is followed by intensive use of specific tools, like FEA(finite element analysis) software, to map out the carbon lay-up.

With FEA software, SCOTT can simulate different forces on a virtual model of the frame and adjust the frame construction accordingly. FEA software enables to create complete virtual prototypes incorporating all the physical phenomena that exist in real-world environments.

With SCOTT’S Evo-Lap technology they model the frame to optimize the surface area, simulate tube structures with different ply orientations, observe the results of using different configurations, and test the stress distribution in different areas of the frame. Thanks to this extensive computer modeling, they’ve optimized the carbon layers in all the parts of the frame. When the parts were bonded together in the first prototypes, the result was a super light and compact frame without a sacrifice in the stiffness, comfort or impact resistance. The entire range benefitted from SCOTT’S EvoLap technology.



On the new Scale they’ve redesigned all the parts that can give us significant benefits in terms of performance and functionality. On the previous model the support of the dropout was a bulky additional part molded to the carbon chain stay. The new dropouts are designed to be integrated on the thru-axle system thanks to a hollow tubular design that allows a simple and lightweight structure. Available for SRAM and Shimano DM derailleurs, this dropout increases the stiffnessand avoids damage to the frame in case of impacts on the rear derailleur.



On the new Scale and Spark, to provide a clean look and a functional solution for all the different control cable standards on the market, cable routing is fully internal and designed for full length cable housing. Routing the cables internally omits bulky external hardware and looks cleaner. The cables can endure a longer lifetime as they are protected within the frame. The entry points are machined alloy removable inserts that come along with the frame and can be chosen according to the setup of the bike. Assembling an electronic group or a dropper post will not be a problem and the look will always be clean-cut.
