Scott Addict RC 2025: The Ultimate Sub-6kg Road Bike Experience review and buyers guide
Scott has taken the cycling world by storm with its latest release, the Scott Addict RC 2025, a bike that claims to be the lightest production road bike in the world. With a stunning weight of just 5.9kg for the flagship RC Ultimate model, Scott has pushed the boundaries of engineering to new heights. But what makes this bike so special? Let’s dive into the specifications, technology, and ride experience to uncover the magic behind the Addict RC.
A Bold Claim: The Lightest Production Road Bike?
A quick Google search might bring up names like the Specialized S-Works Aethos (6.34kg) or the AX Lightness Vial Evo Ultra (4.8kg). However, while these competitors impress on paper, Scott’s Addict RC has an edge—it balances lightweight performance with real-world usability. Unlike its ultra-light counterparts, the Addict RC includes disc brakes, aerodynamic integration, and ample tyre clearance, making it a versatile race bike that doesn’t compromise practicality.
The Secret to the Addict RC’s Lightweight Design
Scott’s engineers took a no-stone-unturned approach to achieve the Addict RC’s incredible weight savings. Here’s how they did it:
- Frame and Fork: The RC Ultimate’s HMX SL carbon frame weighs just 600g, paired with a 270g fork. Innovative manufacturing techniques ensure minimal carbon waste and a smooth interior finish.
- Component Optimization: Every component, from derailleur hangers to handlebars, was scrutinized for weight reduction. Even the tubes are as thin as 0.6mm in certain areas.
- Wheels and Tyres: The Syncros Capital 1.0 wheels boast full carbon construction with a total weight of just 1,170g. Paired with prototype Schwalbe tyres, this setup significantly contributes to the bike’s featherweight status.
- Group Set: The SRAM Red eTap AXS groupset—the lightest on the market—plays a pivotal role in keeping the weight down without sacrificing performance.

Ride Impressions: A Playful and Stiff Performer
On the road, the Addict RC Ultimate delivers a ride that’s both stiff and responsive. Whether climbing steep gradients or carving through technical descents, this bike feels nimble and controlled. The wide 29mm tyres and 40 mm-deep carbon rims provide a level of comfort and stability that’s often lacking in lightweight road bikes.
Despite its low weight, the bike isn’t skittish. Instead, it offers confident handling, making it suitable for less-than-perfect road conditions.
Small Details That Matter
Scott didn’t just focus on the headline weight; they also included thoughtful features:
- Integrated Tools: A multi-tool stored in the handlebars ensures quick fixes on the go.
- Magnetic Rear Light: Available on select models, this is perfect for visibility during early morning or evening rides.
- Customizable Cockpit: The lightweight Syncros computer mount is both functional and stylish.
