The SCOTT Spark RC Expert evolves our most successful cross-country racing platform into a lightweight, elite performance package—engineered to elevate every trail ride without the top-tier price.
Every detail is designed to create a seamless connection between rider and terrain, delivering the feedback and confidence to commit to every feature up and down the mountain. Developed in close collaboration with our pro riders, the next-generation HMF carbon frame refines the layup and geometry to unlock the ideal balance of speed, agility, and control—whether you're deep into a training block taking to the start line.
Performance extends from the frame to enhance control on demanding singletrack with Fox's 120mm 34SL and Float Factory suspension—a combination engineered specifically for the rigors of modern XC tracks. Dive into technical sections with your wheels planted and your speed exactly where you want it, knowing the setup is working with you every step of the way.
Every component is chosen to make you faster, elevate your capability, and provide lasting durability. Shimano XT Di2's race-ready wireless drivetrain delivers smooth, reliable shifts under pressure, while Syncros Silverton CF2 carbon wheels and cockpit sharpen control. It’s a component selection that moves you with precision across every condition and brings workhorse-level endurance.
Performance also extends to practicality. Improved serviceability and compatibility across a wider range of suspension designs means less time in the workshop and more time on the trail. Smart integration and intuitive engineering make this a bike that's as easy to live with as it is thrilling to ride—built to perform today and last well into the future.
