Scott Spark RC 900 SL AXS 2020
About Scott Spark RC 900 SL AXS 2020
Having already written itself into the history books, the Spark platform has been revamped, and is faster and fitter than ever. With the lightest frame in the RC series, the SL version comes equipped with a FOX 32 SC Fork, a SRAM Eagle AXS 12-speed wireless drivetrain, and a host of Syncros carbon components that will make any rider feel like they can go toe to toe with the world’s finest.

Evo-Lap technology: 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 Scott’s efforts. For this reason, their 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 them to create complete virtual prototypes incorporating all the physical phenomena that exist in real-world environments.
With their Evo-Lap technology they model the frame to optimize the surface area, simulate tube structures with different ply orientations, observethe 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 their 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 their EvoLap technology.
ICCR Cable routing: 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.
SW Dropouts: On the Scale, Spark, Genius, Ransom and Gambler Scott have redesigned all the parts that can give them 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 stiffnessand avoids damage to the frame in case of impacts on the rear derailleur.
Rocker link: 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.
Asymmetric Design: 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.
TwinLoc Suspension System: 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 Scott 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. They also offer 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 they’re 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.
29 Wheels: 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.
