Product Description

Scott: Scale RC 900 SL - 2019

Having already written itself into the history books, the Scale 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 Shimano XTR 1x12 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.



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.


For the new generation of scale Hardtails Scott has created a dedicated RD frame platform. 1x specific drivetrains and a drool worthy spec, these bikes were built to be champions.

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 ourframe. 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.


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.


Racers will attest that ride comfort is an essential element of performance. During the development of a hardtail frame, it is essential to distinguish the areas of the frame optimized for comfort from the ones more related to the stiffness.

Many brands in the market offer different solutions to improve those aspects but most of them are limited only to a component or a specific area of the frame. With SCOTT SDS2 technology they go beyond this approach, reinventing the concept of comfort on hardtail frames without adding additional parts or sacrificing pedaling stiffness. To reach their goal, they ran analysis and testing to optimize different shapes of the tubes on the whole frame along with accurate alignment of the carbon fibers. The result on the new Scale frame is specific, controlled flex in areas that increase rider comfort and guarantee optimal absorption of vibrations not only on the saddle but also when the riders standing up on the pedals.

This approach to comfort must not only accommodate the lightest weight attainable, but also maintain stiffness for the sake of pedal efficiency. Further, superior rigidity of the frame ensures accurate handling in the steeper sections. In the new Scale they’ve considered all these aspects to avoid any undesired flexion that would affect performances either climbing or descending .


On the Scale, Spark and Genius Scott has 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.
