700c, 27-Inch & 650c

Zipp's 303 S Tubeless Disc Brake wheelset provides today's cyclists the versatility they demand with the speed they crave. Expanding greatly on its heritage of conquering the Spring Classics, this 303 wheelset maintains its ideal-for-every-terrain 45mm rim depth but adds a significantly wider internal width to provide greater performance and ride quality in almost every measurable way. This wheelset is tubeless for disc-brake bikes, allowing the ability to run wide tires at lower pressures for race-ready speed on or off the pavement. The 303 S is among our lightest wheelsets, optimized for top aero performance with a 28mm tire but capable of handling gravel tires up to 50mm wide. - Wide rims optimize tire profile to allow lower tire pressure, especially with tubeless. The result is a larger contact patch for increased grip and confident cornering, descending, and handling in wet conditions. - Lower tire pressures and larger volume provides a compliant ride with fewer vibrations. - Significant watt savings when running larger tires at lower pressure. - Wide, hookless rims create a seamless transition to the tire, reducing drag. - Fastest with 28mm, but fits wide gravel tires as well - New Zipp graphics and cosmetic identity that scream speed

Fast, efficient and lightweight for long rides through mountain backroads but still tough and durable for big days across relentless gravel as well as fast rips on technical dirt; the all-new, go-anywhere CXR 1 represents the evolution of versatile performance.

The SLR 1 42 WheelSystems are efficient, lightweight, all-around, carbon road wheels that bring premium-level performance to all riders. Featuring hookless rim design and optimized carbon layup to ensure a robust yet lightweight structure, contemporary wider inner width, low friction hubs offering low rolling resistance, and Dynamic Balanced Lacing (DBL) technology to maintain maximum power efficiency, the SLR 1 42 and SLR 1 42 Disc bring outstanding performance at no compromise. - Hookless rim design enhances overall durability and offers a wider inner rim width without adding weight - Optimized carbon layup features high tensile strength carbon fiber placed at the most crucial points to provide stiff, compliant, and lightweight wheels - Low friction hub with precision machined internals eliminates excessive bearing load, reducing bearing friction, lowering rolling resistance, and minimizing power loss - Dynamic Balanced Lacing (DBL) ensures spokes are set for optimal tension when pedaling, resulting in enhanced durability and transmission efficiency - The enlarged DBL hub flange increases spoke bracing angles, boosting overall torsional, transmissional, and lateral stiffness for better power transfer - Giant's proprietary High Glass Transition Temperature (Tg) resin enhances the rim's overall durability and braking performance - 42mm-deep all-round rim profile with an updated inner width offers better support for today's higher volume road tires

The SLR 2 36 Disc brings the performance gains of a stiff, lightweight carbon wheel to more riders everywhere. Light enough for all-day challenges through the mountains but strong and durable for daily training on variable terrain, the SLR 2 36 Disc’s optimized carbon layup contributes to significant weight reduction for better climbing as Giant hookless technology offers a wide inner rim width for a more confident ride.

The SLR 2 42 Disc WheelSystems are lightweight and robust carbon wheels that are built to last. Combining hookless rim design and optimized carbon layup with a modern, 19.4mm inner width, the SLR 2 42 & SLR 2 42 Disc deliver great value to performance cyclists who require minimal tradeoff between price, weight, and durability. - Hookless rim design enhances overall durability and offers a wider inner rim width without adding weight - Optimized carbon layup features high tensile strength carbon fiber placed at the most crucial points to provide stiff and lightweight wheels - 42mm deep all-round rim profile with a 19.4mm inner width offers better support for today's higher volume road tires

The EC70 AX wheels connect EC70 carbon rims to our proven X5CL hub with 28 3x double butted Sapim straight pull spokes. End cap and axle components are available for all major industry standards. Wide, 24mm internal rims are optimized for gravel tires 35mm and larger, giving you a more confident tire stance for control on the ground during your expansive adventure rides, single track forays and unrelenting gravel races. Our Easton Overland team and SDG Muscle Monster team riders have put these wheels to the test, racing prototypes at DK200, with Amity Rockwell taking the DK Queen title and Amanda Nauman finishing 6th, while at Lost and Found 2019 Michael Van Den Ham came in 4th and Craig Richey took 6th.

Nowadays, road riding is much more than riding on a road. Gravel, rough roads, fenders, lights and racks have broadened the horizon and ER 1400 is the premium alloy choice. It's 20mm, super light and resilient rim and 240s based hub is just what you need when rides lead into the unknown. - 240s based Spline hub with 36t ratchet system - Straight-pull hub and spokes are laced 2-cross - Includes tubeless ready tape and tubeless valve

The pinnacle of aluminum road wheels. The ceramic OXIC surface coating brings brake performance to rim brakes like it has never be seen before. The rims are wide, asymmetric, and lightweight, making for an outstanding stiffness to weight ratio. If set up tubeless, supreme comfort and grip are added to the athletic character. - OXiC rim surface technology for improved braking performance and wear - Tubeless Ready rim compatible with standard clincher tires - 240 hub and ProLock Squorx ProHead spokes built with radial lacing - Factory installed tubeless-ready tape - Includes titanium RWS skewer, tubeless valve and Swissstop BXP blue brake pads
