What makes it special

Thoughtful details. Big possibilities.

01
Lightweight Design
The new Spark RC is one of the lightest new generation 120mm xc race bikes available while at the same time including performance enhancing features and capabilities. Lightweight efficiency defines the foundation of this frame. It is not a design driven by chasing the lowest possible number on a scale, but by the pursuit of meaningful weight distribution that directly translates into performance on the trail and racetrack. Every gram removed has a purpose, and every structural decision is measured against stiffness balance and long-term reliability.
02
Ride Dynamics
Every detail of this bike’s design has been carefully engineered to maximize grip and traction, to maintain stability, and give riders the confidence to push harder and ride faster. Ride dynamics are about speed through control, it’s about grip and stability. The Spark RC frame is engineered as a complete system, where controlled flex enhances both grip, line control and efficiency. Lateral, vertical, and torsional flex are carefully tuned across the entire frame to work together seamlessly. The result is a bike that feels responsive, predictable, and fast on any terrain.
03
Easy Access
Service and suspension setup are intuitive thanks to the accessible frame with top and rear frame covers. These magnetic and clipped covers provide easy access to the shock and interior, making workshop service fast and hassle-free. Both frame covers are sealed to protect the shock from dirt and water ingress. When running a split top cover, especially in combination with electronic shocks, dust and moisture entering the frame is unavoidable. To address this, a large drain hole in the frame efficiently evacuates any accumulated water. The shock shaft and seals remain fully protected, ensuring long-term consistent suspension performance in all conditions

Engineered to create a seamless connection between rider and terrain, it ensures every pedal stroke and line choice is met with responsiveness and control—so you can focus on the ride, not the bike. Every gram has been considered to craft a bike that accelerates effortlessly, navigates technical terrain with agility, and responds instantly to rider input. We’ve achieved this with our HMX-SL frame—our lightest and most refined yet.

But true performance isn’t just about weight- it’s about balance. The Spark RC SL geometry is meticulously engineered to put you in control, elevating cornering confidence, making climbing efficient, and keeping descents stable—all without interruption. The advanced suspension kinematics via RockShox Flight Attendant delivers optimal suspension settings in real time, anticipating the trail ahead, so you can focus on the ride regardless of how challenging the trail.

Your wheels stay planted and your ride smooth as the setup elevates ride feel and adapts to conditions to flow through every section. The result is a bike that evolves with the terrain, so you can ride with instinctive confidence—because the best rides happen when the bike feels like an extension of you. Equipped with a top-tier build, the Spark RC SL feels limitless and ready for your fastest rides.

The SRAM XX SL Eagle AXS Transmission drivetrain, DT Swiss wheels, Ceramic Speed pivot bearings and titanium frame hardware enhance speed, accuracy, and control, ensuring the bike is as capable on your local trails as it is on World Cup start lines. Performance also extends to practicality. With a straightforward design that prioritizes ease of maintenance, you’ll spend less time in the workshop and more time riding.

Every detail is considered to support your experience—because the best rides are the ones where the bike disappears, and all that’s left is the trail ahead.
