Scott Spark RC 900 Pro 29" Mountain Bike 2020 - XC Full Suspension MTB
Anyone who ever dreamed of a pro-cross-country racing career has dreamt of the Spark RC 900 Pro. The 1x-specific Spark RC frame design and lightweight, hyper-efficient TwinLoc Suspension System are made for pure, on-course performance. The Pro build includes a Shimano XTR 12-speed drivetrain and XTR brakes and is made to go the distance with premium Syncros components completing this race-worthy package in style.
Technologies:
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 fibres 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 modelling, 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.
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 pedalling 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. We 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. We can eliminate the "long travel effect" that can rob your pedalling efficiency, but we'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.
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 moulded to the carbon chainstay. The new dropouts are designed to be integrated on the thru-axle system thanks to a hollow tubular design that allows a simple and lightweight 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.
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.
Axle Tool:
Working together with DT Swiss, we completely revisited the shape of the thru-axle lever to make it more ergonomic and to perfectly fit to our frame. Additionally, we introduce 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.
Occasionally, without notice, manufacturers change product design and/or specifications.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
