Chris King R45D Disc Centrelock Rear Hub

It is a preferred rear hub option for Brisbane bike shops, experienced wheel builders, and professional bicycle service centres building premium disc brake road wheels for racing, endurance, and high‑performance riding.

RingDrive Engagement and Power Transfer

At the heart of the R45D rear hub is Chris King’s patented RingDrive system, featuring 45 simultaneously engaged points of contact. Unlike traditional pawl systems, RingDrive distributes load evenly across all engagement surfaces, resulting in near‑instant engagement with minimal drag.

This design provides exceptional responsiveness when sprinting, climbing, or accelerating after corners, while maintaining smooth, quiet rolling speed during steady efforts. For Brisbane riders racing criteriums, attacking rolling terrain, or training on long flats, this balance of efficiency and engagement is a major performance advantage.

Legendary Chris King Bearings

The R45D rear hub uses Chris King’s in‑house angular‑contact bearings, designed to handle both radial and axial loads common in disc brake applications. These bearings are manufactured internally to strict tolerances and are known for exceptional durability and smoothness.

Unlike disposable cartridge bearings, Chris King bearings are serviceable and designed to wear in over time, becoming smoother with use. This makes the hub ideal for Queensland riders covering high weekly mileage in varied road conditions.

Disc Brake and Axle Compatibility

The rear hub uses the Centrelock disc brake standard, offering secure rotor mounting and easy servicing. It is designed for modern road frames using a 142 mm x 12 mm thru‑axle, now standard across disc brake road and endurance platforms.

This configuration integrates cleanly with contemporary road frames commonly sold and serviced through Brisbane cycling retailers.

Serviceability and Long‑Term Value

The R45D rear hub is fully serviceable and rebuildable, ensuring decades of use rather than seasons of ownership. Routine maintenance and complete overhauls can be performed using either the Chris King Universal Hub Service Tool or the R45‑specific service tools.

Chris King supports the hub with a lifetime warranty, making it a long‑term investment for riders, wheel builders and mechanics who value performance parts with lasting value.

Manufacturing and Quality

The Chris King R45D Disc Centrelock Rear Hub is engineered, manufactured, and assembled in Portland, Oregon, USA. Tight machining tolerances ensure consistent alignment, smooth bearing operation, and reliable disc brake performance.

This commitment to domestic manufacturing and premium quality control is a key reason Chris King hubs are widely specified by high‑end Brisbane bike shops and custom wheel builders.
