Chris King R45 Ceramic Rear Hub

The mission when designing the R45 hub was to make a lighter and stronger hub for the demands of road racing. The sleek looking hubshell has a classic sculpted look with no extra and unneeded material to shave weight. Inside the hubshell is a massive 17mm alloy axle for the ultimate in rigidity and stiffness. These design elements helped shave over 20% of weight over the all-ready light Chris King Classic hubs and bring the R45 in at a scant 215 grams.

The rear freehub body is made of lightweight alloy to super-tight tolerances. Shimano and SRAM cassettes fit the splines with absolute precision. The engagement system is completely serviceable and from our experience, nothing engages quicker. There are two bearings in the freehub body and two on each side of the hubshell for an unprecedented 4 bearings per rear hub.

These particular R45 hubs feature ceramic bearings. Now, we all know that ceramic bearings spin faster than their steel counter parts and are more durable. We also know there are plenty of ceramic bearing hubs on the market. What is unique about the Chris King ceramic bearings is the fact that they are made completely in house. Being fanatics about quality control, the folks at Chris King simply could not find a ceramic bearing that met their standards, so they designed and built them themselves! This proprietary bearing design allowed King to place more rolling elements per bearing for greater durability and precision. The R45 ceramic bearings also feature lightweight, low-friction seals for fast rolling and can be easily serviced at regular intervals.
