The R45 rear hub is lighter and more aerodynamic than most built-to-last hubs on the market. The hub combines a redesigned RingDrive system with 45 teeth for lower drag and near-instant engagement with a lightweight hub body and our legendary made-in-house bearings. All Chris King rear hubs come with that signature, angry-bee sound, include a King Lifetime Warranty and are Engineered, manufactured, and assembled in Portland, Oregon USA.

• Bearings are heat-treated and have surgical grade steel races that are machined simultaneously to ensure perfect matching. The quality and speed of these bearings is what you will feel (and hear) on every ride
• Easily serviceable with a 2.5mm hex and pick or pen knife
• Completely re-buildable with the R45 Hub Service Too
