The all NEW Spark RC 900 World Cup is a cross-country full-suspension bike on a mission to win. Keeping the ride smooth, a 100mm travel FOX 32 SC Float Performance Elite fork is paired with a custom FOX NUDE 3-mode rear shock via TwinLoc suspension control. The SRAM X01 Eagle 12-speed drivetrain will move you up the trail and Shimano XTR disc brakes will slow you down when it’s time to step onto the podium.
HMX Carbon Fiber
While Scott already use the proven HMF composite fiber on all their 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 allowed Scott 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.
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.
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, 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 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.
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, Scott 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.Our TwinLoc remote cable can be routed cleanly into the down tube.
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.
