The Swissstop Catalyst One Centrelock Disc Brake Rotor is a high-performance brake rotor built for consistent braking, stable heat control, and reliable power across all riding conditions. It uses the tested and proven Catalyst brake ring, which is designed to manage heat and maintain braking consistency under load. The Centrelock interface ensures fast and secure installation. With a 1.95mm thickness and optimised profile, it delivers strong bite and reduced fade on long descents.Key Features and Benefits:Tested and proven Catalyst brake ring design: The brake ring uses a refined profile that improves heat distribution across the rotor surface. This reduces localised hot spots and keeps braking force stable. You get consistent braking performance during repeated or sustained braking, especially on long descentsCentrelock mounting interface: The Centrelock system provides a secure spline-based fit with even load distribution across the hub interface. This reduces the risk of rotor movement and simplifies installation. You benefit from a stable setup with faster fitting and reliable alignment1.95mm rotor thickness: The increased thickness improves structural stiffness and heat capacity. This helps the rotor resist flex under braking load and absorb more heat before performance drops. You gain stronger braking feel and reduced fade in demanding conditionsUCI approved 140mm and 160mm sizes: The rotor meets UCI regulations for competitive use in approved sizes. This ensures compliance for race environments and confirms consistent performance standards. You can use it in events with confidence in both legality and functionConsistent braking control is critical when speeds rise and terrain becomes more demanding. The Catalyst brake ring is engineered to keep braking force predictable, even as temperatures increase. Its design supports stable friction levels and reduces performance loss during repeated braking. Combined with a stiff rotor body and precise Centrelock fit, it helps maintain control and braking accuracy across varied riding conditions.This rotor is built for riders who need dependable braking without added complexity. Its proven design, easy installation, and stable performance make it a strong upgrade for modern disc brake systems. Choose a rotor that delivers control when it matters most.
