Chris King R45 Road Hub Rear

A lightweight hubset designed expressly for the demands of road racing.
28 hole drilling, silver.


  • The R45 hubset is 20% lighter than our Classic hubset.
  • We designed sleek new hubshell bodies and new 17 mm axles. That's 17 mm from dropout to dropout resisting deflection during cornering or when the power is full on.
  • We designed a driveshell with a twin bearing design that responsibly removed as much weight as we could from the inner components.
  • Even our patented RingDrive engagement system was redeveloped resulting in a quiet, fast-engaging 45-tooth stainless steel system unique to the R45 rear hub.


  • We 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.
  • Our proprietary bearing design allows us 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 only a single 2.5 mm hex wrench and penknife.
