CAMPAGNOLO Bora WTO DB 45 C23 2WF CL Disc Tubeless Road Rear WheelExperience the pinnacle of aerodynamic performance and all-around versatility with the CAMPAGNOLO Bora WTO DB 45 C23 2WF CL Disc Tubeless Road Rear Wheel. A masterpiece of Italian engineering, this wheel is meticulously designed for the modern road cyclist who demands uncompromising speed, stability, and efficiency on every ride. Whether you´re powering on the flats, conquering challenging climbs, or descending with confidence, the Bora WTO 45 is your ultimate performance upgrade.The 45mm rim profile is the heart of its Wind Tunnel Optimized (WTO) design, striking the perfect balance between aerodynamic advantage and superb handling. It slices through the air with minimal resistance, saving you precious watts and allowing you to maintain higher speeds with less effort. Unlike deeper rims, the 45mm profile remains exceptionally stable and predictable in crosswinds, giving you the confidence to push your limits in all weather conditions.This latest evolution features a C23 internal rim width, perfectly optimized for today´s wider road tyres (28mm and up). This wider stance creates a more seamless interface between the tyre and rim, improving aerodynamics, increasing comfort, and providing a larger contact patch for enhanced grip and cornering precision. The 2-Way Fit (2WF) technology offers you the freedom to choose your preferred setup, whether it´s a traditional clincher or a modern Tubeless system for lower rolling resistance, superior comfort, and improved puncture protection.At the core of this wheel´s incredible rolling efficiency are the USB™ (Ultra Smooth Bearings) ceramic bearings, which dramatically reduce friction, ensuring that every ounce of your power is translated into forward motion. The iconic G3™ spoke pattern is not just visually stunning, it provides a perfectly balanced and reactive wheel by counteracting the rotational forces from the drivetrain and Disc Brake system, resulting in superior power transfer and long-term durability.Key Benefits:* Aerodynamic Excellence: The 45mm WTO profile is engineered to minimize drag, providing a tangible speed advantage on flat and rolling terrain.* All-Round Versatility: The ideal rim depth for a single, do-it-all wheelset, offering aerodynamic gains without compromising on weight for climbing or stability for descending.* Superior Rolling Smoothness: USB™ ceramic bearings deliver an incredibly smooth and efficient ride, reducing friction to an absolute minimum.* Enhanced Comfort and Grip: The C23 internal width is designed for wider tyres, allowing for lower pressures, a smoother ride, and confident handling.* Exceptional Stiffness and Reactivity: The G3™ spoke pattern ensures optimal tension balance, delivering immediate power transfer and a highly responsive feel.Main Features:* Wind Tunnel Optimized (WTO) 45mm rim profile for maximum aerodynamic penetration.* C23 internal channel for a perfect pairing with modern, wider road tyres.* 2-Way Fit™ system for full compatibility with both tubeless and clincher tyres.* Aero Mo-Mag™ internal nipple system for a cleaner aerodynamic profile and easy maintenance.* G3™ spoke pattern with 24 aero elliptical spokes for balanced tension and performance.* USB™ Ceramic Cone and Cup bearing system for ultimate smoothness.* AFS (Center Lock) disc brake mount for powerful and reliable stopping.This Rear wheel is specifically engineered for performance Road Cycling, making it the perfect choice for racers and passionate cyclists seeking to elevate their ride.Technical Specifications:* Wheel Size: 28´´- 700* Discipline: Road Cycling* Brake Type: Disc Brake (AFS Center Lock)* Tyre Compatibility: 2-Way Fit (Tubeless, Tubeless-Ready, Clincher)* Rim Height: 45 mm* Internal Rim Width: 23 mm* External Rim Width: 29 mm* Spoke Count: 24* Spoke Pattern: G3™* Bearings: USB™ Ceramic, Cone/Cup System* Hub: Monolithic Aluminium Hub, Black* Axle Compatibility: 12x142 mm Thru-Axle* Weight: 815 g* System Weight Limit (Rider + Bicycle): 120 kg
