Perhaps the best description of single speed mountain biking is this: ";Always the wrong gear."; While singlespeeding is a challenge, there is no question in its rise to popularity in recent times. Maybe you don't always want a couple dozen gears and gobs of travel out on your favourite rides. And maybe sometimes the challenge is the best part of the ride. But no matter the motivation to take on the test of that single wrong gear, you can always have the right hub.
The Chris King ISO Single Speed Disc Rear Hub is purpose built for singlespeed riding. Wide-spaced, equal size aluminium hubshell flanges set the base for a low-dish wheel; the less the dish, the stronger the wheel. Building strength upon strength, our renowned sealed bearings turn around a one-piece 19.5 mm dropout-to-dropout axle while our patented RingDrive engagement provides near instantaneous power transfer.
We designed a custom singlespeed specific driveshell that allows for the wide spaced flanges of the hubshell. This aluminium driveshell allows you to use our lightweight spacer and lockring system to dial in your chainline with our FunBolts keeping it all in place.
FunBolts are our hollow stainless steel fixing bolts with an aluminum cap sleeve. At 42 grams per pair they ably define our concept of responsibly light.
User serviceability is a hallmark of all Chris King hubs. With the ISO Single Speed Disc all you need is a 2.5mm hex-head wrench to adjust the bearing preload or to remove the axle clamp and service the bearings. As with every hub we manufacture, this hub is backed by a 5-year warranty.
Pair with our ISO Disc Front Hub for a complete hubset.
