SDS: Shock Damping System SDS minimizes high frequency vibration from the road, enabling a damping effect without losing performance. Scott has engineered a balance of vertical compliance and lateral stiffness in both the rear triangle and the fork. - Vertical compliance is a measure of how smoothly a bike rides. By maximizing vertical compliance, SDS cancels road vibrations, increasing rider confidence, stability and comfort. - Lateral stiffness correlates to responsiveness during sprinting, acceleration, and climbing.   S-bend Construction Each tube profile is designed to absorb both abrupt and high frequency vertical input with no compromise in lateral stiffness. We've created an original tube shape that allows controlled deformation in the rear triangle called an S-bend. The SDS rear stays enable this S-bend deformation via unique tube structure, thickness, and shape in specific sections of the chain stays, seat stays and fork.   Carbon Fork featuring SDS The new 330 gram (.72 lb) CR1 fork has an improved shape and carbon dropouts. Now featuring SDS, the CR1 fork provides maximum comfort without compromising steering control. It is lightweight and very stable, providing the utmost performance whether climbing or descending.   Design and Shape The overall frame design combines fluidity with the mechanical concept. Smooth continuous lines extend from the head tube and along the top tube. Each portion of the frame and fork was designed in unison to create an esthetic that is both functional and visually appealing.   IMPT - Integrated Molding Process Our engineers have developed IMPT, the newest technology applied to carbon production. The toptube, headtube and downtube are produced in a single step using a top-secret process. Our proprietary process allows for lighter construction by removing 11% of the material from the headtube intersection. IMPT also increases strength by utilizing high modulus stressed fibers with more precise fiber placement in critical areas. Additionally, our frames benefit from our Naked External TubesetT (NETT), which shaves precious grams by eliminating the outer cosmetic carbon layer.   HMX-NET Carbon Fiber While we already use the proven HMF composite fiber on all our composite high-end bike models, we 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 allows us to reduce weight and improve riding characteristics.
