The Spark RC 900 World Cup is a cross-country full-suspension bike on a mission to win. Keeping the ride smooth, a RockShox SID Ultimate fork is paired with a custom RockShox NUDE 3-mode rear shock via our TwinLoc Suspension System. The SRAM Eagle AXS 12-speed wireless drivetrain will move you up the trail and SRAM Level disc brakes will slow you down when it's time to step onto the podium. 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 our efforts. For this reason, our 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, we 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. - With our Evo-Lap technology we 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, we’ve optimized the carbon layers in all the parts of our 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 our 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 we’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 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. Rocker Link - The Spark carbon linkage is constructed with a compression molding process. It’s 37g lighter than the aluminum 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. Key Features - Spark RC Carbon HMX Frame - RockShox SID Ult.
