Chris King R45 Campagnolo Hub Bearings – The Heart of Your WheelsetRestore the legendary performance of your wheelset with the official Chris King R45 Campagnolo Hub Bearings. Designed as a direct replacement spare part, this bearing kit is the ultimate way to breathe new life into your R45 hubs, ensuring they spin with the same buttery-smooth precision as the day they were built. Engineered for riders who demand uncompromising quality and longevity, these bearings are not just components, they are an investment in countless miles of flawless performance.Experience the defining characteristic of Chris King components: bearings that get better with age. Unlike disposable cartridge bearings that degrade over time, our in-house manufactured steel bearings feature races that burnish and self-polish with use. This unique process means your hubs will actually roll smoother and faster after their initial break-in period, developing a ride quality that is simply unmatched. This commitment to durability ensures that you are investing in a part that is designed to last the lifetime of your hub with proper service.The secret to their superior performance lies in the meticulous manufacturing process. Each bearing is made from a single piece of high-quality steel bar stock, heat-treated in a single batch to create perfectly matched inner and outer races. This precision matching results in a bearing with exceptionally low drag and unparalleled smoothness, translating to more of your power hitting the pavement. Feel the difference in every pedal stroke, whether you are accelerating out of a corner, holding speed in the peloton, or tackling a long, grueling climb. Fully serviceable and built to be maintained rather than replaced, these bearings embody a philosophy of sustainable, long-term performance.Main Features:* In-House Manufacturing: Proudly designed, manufactured, and assembled in our Portland, Oregon facility for complete quality control.* Matched Race Sets: Inner and outer races are machined simultaneously and kept as a matched pair throughout the entire process, ensuring perfect alignment and function.* Burnishing Action: Specially engineered races that self-polish over time, reducing friction and becoming smoother and faster with every ride.* Fully Serviceable: Designed for easy cleaning and re-greasing, allowing you to maintain peak performance for years and extend the life of your investment.* Precision Ground: Engineered to exacting tolerances for minimal friction and maximum rolling efficiency.Technical Specifications:* Product: Chris King R45 Campagnolo Hub Bearings* Category: Spare Parts* Subcategory: Hubs* Attribute: Bearings* Compatibility: Specifically designed for Chris King R45 hubs equipped with a Campagnolo freehub body.* Type: Sealed Steel Cartridge Bearings* Kit Contents: Complete bearing set required for servicing one R45 Campagnolo rear hub.* Origin: Made in the USA
