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


On the Scale, Spark, Genius and Ransom, 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.


On the Scale, Spark and Genius Scott has 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 light weight structure. Available for SRAM and Shimano DM derailleurs, this dropout increases the stiffness and avoids damage to the frame in case of impacts on the rear derailleur.


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.


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.


Working together with DT Swiss, Scott completely revisited the shape of the thru-axle lever to make it more ergonomic and to perfectly fit to their frame. Additionally they introduced 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.


With TwinLoc, a rider can effectively control the complete frame, fork, and shock as a system. Why does this matter? A bike with 150mm of suspension travel, correctly set up, has more sag than a bike with 130mm. It's that extra travel that makes it more fun to ride and more capable on the descents, but the greater sag has an oversized effect on the bike's geometry and climbing performance. That's where TwinLoc matters.

TwinLoc helps manage the sag effect in several ways. Whereas most systems only increase low-speed compression in an effort to gain pedaling efficiency, TwinLoc allows us to not only change compression damping, but also to change the spring curve, dynamically altering the geometry of the bike. In Trail mode, the shock is not only firmer, but it has dynamically less travel. The bike sits higher, maintains a steep seat angle for those climbs, and becomes more agile. Scott also offers a third, full lockout mode for going up in the most efficient manner possible.

These unique settings optimize climbing geometry, even on longer travel bikes. They can eliminate the "long travel effect" that can rob your pedaling efficiency, but are not robbing you of the full-fun, 150mm travel when you point it downhill. From a race setting, to a lunch ride, to an after work trail shred, being able to switch from mode to mode depending on a trails profile at the push of a lever is paramount to riding faster and having a damned good time.


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 27.5” 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
