ISO 20mm Thru-Axle Front Disc Hub
This design was a challenge. As with all of our products, we wanted the 20mm Thru-Axle Front Disc Hub to be the best that money could buy. Our design criteria were simple: a one piece super strong axle that could be adjusted in the field with a single wrench, without removing the wheel, the toughest bearings possible and it needs to build an excellent wheel while still looking sharp and not weigh in like a stuffed pig.
We had to design an entirely new bearing for this guy. It is about the same size as a one inch headset bearing. Bigger than anything else out there. A high strength, 110mm, one piece aluminum axle is capped with 2 stainless steel axle biters to hold onto your fork legs like crazy. Why a one piece axle? Some other hubs require that you adjust the hub bearings by clamping the fork legs together harder, while others have no adjustments at all. You want strong? Looking for reliability and ease of adjustment? Look no further.
The 20mm Thru Axle Front hub is compatible with the ISO disc standard, available in all of our colors, in 32° and 36°.
Ceramic Bearings - Made in-house
We make our own ceramic bearings and we build them to the same exacting standards as our classic, time-tested stainless steel ball model. Pairing the corrosion resistance of ceramic balls with our proven sealing system allows for greater flexibility with greasing options. We build our ceramic bearing ISO hubs with a very small amount of silicone-based lube for a system with very low drag. Take advantage of our user-serviceable bearings and run minimal lubrication for the ultimate in race-day performance.
Stainless Steel Bearings - Made in-house
The ISO hubsets also have the option of stainless steel sealed bearings. As with every King bearing, these bearings are made in-house in Portland, Oregon and individually hand-checked for precision and smoothness.
Converting our 20mm ISO front hub to a different axle standard is simple and easy. Our one piece axles are quickly interchangeable allowing you to easily transfer your Chris King equipped wheels between bicycles. Please refer to the Hub Specs Menu for specific axle compatibility.
