The Lightweight King of the Mountain.
The Scott Addict RC Ultimate HMX SL is the pinnacle of road racing technology, engineered with a single goal: to be the lightest, fastest production race bike on the planet. Utilizing Scott's most advanced HMX SL carbon fiber, this frameset offers an incredible strength-to-weight ratio that allows for explosive acceleration and effortless climbing.
Designed for those who refuse to compromise, the Addict RC Ultimate features fully integrated cable routing and aggressive race geometry, ensuring that every watt of power you produce is translated directly into forward momentum.
Key Features
HMX SL Carbon Construction: Scott's highest grade of carbon fiber, utilizing nano-technology to create a frame that is both exceptionally stiff and record-breakingly light.
Fully Integrated Cable Routing: Both mechanical and electronic shifting cables are hidden internally through the handlebar, stem, and frame for a clean aesthetic and improved aerodynamics.
Hollow Structure Design: The entire frame is built with a hollow interior to minimize weight while maintaining structural integrity and high-speed stability.
Road Race Geometry: Developed in conjunction with professional riders to provide a responsive, "pro-tour" handling feel that excels in both sprints and high-speed cornering.
Ultra-Lightweight Fork: The HMX SL carbon fork is specifically tuned to provide precise steering and vibration dampening without adding unnecessary bulk.

✅ Why This IS For You
Elite Climbers: If your goal is to set KOMS on the steepest gradients, the sub-700g frame weight provides a mechanical advantage that is hard to beat.
Custom Build Enthusiasts: This frameset is the perfect "blank canvas" for a world-class super-bike build, allowing you to choose every component to meet your exact weight and performance targets.
Serious Racers: For those competing at a high level, the combination of aerodynamic integration and high-stiffness carbon ensures no energy is wasted in the heat of a race.
❌ Why This May NOT be for you
Casual Coffee Riders: The aggressive race geometry is designed for speed and power; if you prefer a relaxed, upright "endurance" position, the Scott Addict (non-RC) range may be more suitable.
Budget-Conscious Builders: HMX SL is Scott's most expensive carbon layup. If you want the same geometry at a more accessible price point, the HMX (RC Pro) or HMF (RC Team) models offer similar performance with a slight weight penalty.
Rough Terrain / Gravel: While it has generous 32mm tire clearance for a race bike, this is a dedicated road performance machine. For unpaved adventures, you should look at the Scott Addict Gravel series.
BFC Pro Tip
Because the HMX SL carbon is so specialized and thin in certain areas, always use a high-quality torque wrench during assembly, especially for the seat post and cockpit. Even a slight over-tightening can damage the carbon structure. If you’re planning a top-tier build with this frame, let’s sit down for a BFC Pro Consultation to ensure your component choices (like integrated bar/stems) match your fit perfectly before we start the build!
