during a recent king rear hub overhaul i thought i’d take a couple of pics of their ring drive system….it’s a beautiful design that’s not as prone to typical pedal torque wear and tear. Why ?? Because much of the loads are displaced from their helical spline, between the spline and the engagement teeth they create a drive that can handle up to 800 ft/lbs of torque…that’s pretty darn good. But besides all of this technical information the true beauty of these hubs is how easily they can be COMPLETELY torn down for an overhaul with the use of the King Hub Service tool. This hub shown here has 4 years of use logged in and the teeth still look brand spankin’ new. The bearings, still buttery smooth. King hubs are expensive but we think they’re worth every bloody cent.
