Scott: Spark RC 900 SL - 2019
Scott: Spark RC 900 SL - 2019
The SCOTT Spark has the most successful pedigree of any cross-country full suspension bike ever made, and that lineage is fully expressed in the Spark RC 900 SL. At under 1800g with rear shock, this race-bred, 100mm travel frame is the lightest Spark ever made. The Spark RC 900 SL is dressed to win with Scott's TwinLoc Suspension System with a FOX 32 SC Factory Air fork, Shimano XTR 12-speed drivetrain, and Shimano XTR brakes.
Mountain bikes are your ticket to off-road bliss. Racing, climbing, descending and everything in-between, these rigs are ready for anything the mountains can serve up.
Scott's Cross Country bikes have won World Cups, World Championships and Olympic Medals. Find out what makes these race machines the most sought after by athletes worldwide.
The Spack RC is the winningest full suspension XC bike to date. The RC family was designed for racers, by racers , and is here to dominate.

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 Scott's 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.
Scott's integrated chain guide was developed in collaboration with the SCOTT SRAM 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.
HMX SL CARBON FIBER
Strength and stiffness are two very different properties of a material. Carbon fibers are available with a wide range of each characteristic. Typically, very stiff fibers are less strong. HMX-SL uses a blend of the highest performance fibers available today, and applies them strategically throughout the frame. MR70 is a new introduction to Scott's layup collection. The raw fiber undergoes an extended refinement process to reach extremely high levels of strength with good stiffness. To further boost frame stiffness, tapes of the exceptionally stiff YS60 fiber are applied along the length of the tubes. Fibers impregnated with a nano resin are also employed in some areas of the frame. This specialist resin improves cohesion between the fibers to toughen the structure.
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.
On the Scale, Spark and Genius Scott 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.
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 them to build a very compact frame and shock package, which integrates tightly to the seat tube. They 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 (their 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 main pivot, we 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.
TWINLOCK 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 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.
