Description
20% lighter, 11-speed compatible and available in a vast range of colours to suit your wheel building needs, the Chris King R45 11 Speed Shimano Rear Hub is a highly regarded and desirable offering. The high-quality engineering within all Chris King hubs keeps wheels spinning faster for longer, and not to forget the buzz you get from that freewheel!
The 17mm axles and sleek new hub shell bodies are behind the 20% lighter overall weight of the R45, but the twin bearing design adds to this too and removes a vast amount of weight from the inner components without affecting on any of the ride quality these hubs are known for. The RingDrive engagement system is completely unique to the R45 rear hub and creates a fast-engaging 45-tooth stainless steel system that’s smooth and quiet when engaging.
Chris King designed and built a bearing specifically for the R45 hubset. As with every King bearing, these stainless steel sealed bearings are made in-house in Portland, Oregon and individually hand-checked for precision and smoothness. The proprietary bearing design allows them to place more rolling elements per bearing meaning greater durability and precision. R45 bearings also feature lightweight, low-friction seals for fast rolling and can be easily serviced at regular intervals using the R45 Hub Service Tool.
