Zipp 303 SW Carbon Tubeless Disc Brake Front Wheel

Zipp’s 303 SW Carbon Tubeless Front Wheel is built for speed, comfort, and control across road, gravel, and cyclocross terrain. Its wide-rim design enhances aerodynamics and reduces rolling resistance, while integrated tyre pressure monitoring ensures optimal performance. With improved impact strength and smooth hub performance, it delivers a confident, efficient ride on mixed surfaces.

Key Features and Benefits:

• Integrated Zipp AXS Wheel Sensor for tyre pressure monitoring: Provides real-time pressure data directly from the rim, with no need for a valve-mounted device. Enables fast, accurate adjustments before and during rides, leading to better performance and early issue detection.
• Wide 25mm internal rim width with 40mm depth: Supports modern, wider tyres for better aerodynamics and lower rolling resistance. This increases speed and smoothness across mixed surfaces and rough roads.
• Optimised for 30–35mm tubeless tyres: Matches tyre volume with rim design to support lower pressures. Reduces rider fatigue by absorbing road chatter and smoothing out uneven terrain.
• Refined hookless carbon construction with improved layup: Delivers nearly 10% more impact strength without added weight. Offers greater durability while maintaining a lightweight build for responsive handling.
• ZR1 hub with stainless steel bearings: Improves rolling efficiency and durability. Ensures smooth, consistent performance over time, even in tough riding conditions.
• Aerodynamic rim profile with smooth tyre transition: Reduces drag and improves stability, especially with wider tyres. Enhances speed and control across variable wind and road conditions.
• Pinch-flat resistance via protective rim shape: Shields tyres from sharp rim contact during impacts. Reduces the chance of flats, especially at lower pressures on rough surfaces.
• Centre-lock disc brake compatibility with CX-Sprint spokes: Provides strong, consistent braking power with reliable wheel stiffness. Ensures dependable handling and stopping performance in all conditions.

The key outcome for most riders is confidence in mixed-surface performance without sacrificing speed. The 303 SW achieves this by combining aerodynamic efficiency, tyre pressure control, and robust impact protection. Its wide rim platform, refined carbon layup, and smart pressure monitoring system create a high-performing wheel suited for road, gravel, and off-pavement conditions.

Enhance your ride with a front wheel designed for today’s real-world routes. From racing to exploring, the 303 SW provides the speed, control, and strength you need for reliable all-road performance.
