FULCRUM Racing Quattro Carbon Rear Wheel: Aerodynamic Performance and Superior ControlElevate your ride with the FULCRUM Racing Quattro Carbon rear wheel, a masterpiece of engineering designed for the discerning cyclist who demands a perfect balance of speed, stiffness, and all-around performance. This wheel is not just an upgrade, it´s a transformation for your bike, delivering tangible aerodynamic gains and confident handling on every road, from flat-out sprints to challenging climbs and technical descents. Its versatile profile makes it the ultimate choice for riders seeking one high-performance wheelset to conquer every challenge.The Racing Quattro Carbon is built to cut through the wind and convert every watt of power into forward motion. The 40mm deep rim profile has been meticulously developed to offer a significant aerodynamic advantage without being a handful in crosswinds, providing stability and speed when you need it most. This translates to holding higher speeds with less effort, giving you the edge on long solo efforts or in the heat of competition.Key Benefits:* Unmatched Braking in All Conditions: Experience a new level of braking confidence on a carbon surface. Featuring Fulcrum´s exclusive AC3™ (All Conditions Carbon Control) technology, the braking track has a laser-etched micro-texture that removes water and debris, dramatically increasing friction and delivering powerful, predictable braking performance that is nearly on par with aluminum rims, especially in wet weather.* Aerodynamic Superiority: The 40mm deep, full carbon rim profile is a sweet spot for versatility, providing a clear aerodynamic benefit on flat and rolling terrain while remaining lightweight and responsive enough for spirited climbing. It's the ideal do-it-all depth for performance riding.* Enhanced Stiffness and Reactivity: Feel the immediate response with every pedal stroke. The wheel´s construction, featuring an oversized drive-side flange and the Two-to-One™ spoke ratio, doubles the number of spokes where torque is greatest. This design prevents energy dispersion and translates your power directly into explosive acceleration and speed.* Smooth-Rolling Durability: At its core, a high-quality aluminum hub houses adjustable, high-grade steel bearings, ensuring exceptionally low friction and a consistently smooth roll, mile after mile. This focus on durability means you can count on your wheels for seasons of hard riding.Main Features:The FULCRUM Racing Quattro Carbon is packed with technology to enhance your ride. The 17C internal rim width provides a perfect base for modern 25mm and 28mm clincher tires, improving the tire´s profile for better grip, comfort, and lower rolling resistance. The rim bed is free of spoke holes thanks to MoMag™ technology, creating a stronger, more uniform structure that doesn´t require rim tape for a tubeless setup (when using a tubeless kit) and reduces the risk of stress-related failures. Aero straight-pull spokes are locked in place by the Anti-Rotation System™, ensuring they maintain their optimal aerodynamic position and prevent any loss of tension over time.---Technical Specifications:* Tire Type: Clincher* Wheel Size: 28´´- 700c* Discipline: Road / Triathlon* Rim Material: Carbon* Rim Profile: Symmetrical* Rim Height: 40mm* Rim Width (Internal): 17mm (C17)* Braking System: Rim Brake* Braking Surface: AC3™ (All Conditions Carbon Control) Treatment on Carbon Braking Surface* Position: Rear* Hub: Aluminum with Aluminum Flanges* Bearings: High-Quality Adjustable Steel Bearings* Spokes: 21, Stainless Steel, Double Butted* Spoke Lacing: Two-to-One™ (14 left - 7 right)* Nipples: Aluminum* Weight Limit: 109 kg (Cyclist)
