Months of design and testing went into Chris Kings ISO disc hubset. During the development process, they had to adapted their machines to use larger bar stock when they were make the hub shells. This manufacturing improvement allowed them to increase the spoke flange diameter significantly. A larger spoke flange spreads the spoke holes away from each other. Also, you can use shorter spokes to build a more durable, stiffer and stronger wheel.
Make no mistake, these are not "disposable" parts. There are a lot of super light hubs out there, but will they still be working in 2 years? How about 5? If you ride a lot, 5 years is a lot of panic stops, high speed feathering and braking bumps. Like all of Chris King's other hubs, these carry a 5 year warranty. It is easy to make a really light hub, not so easy to make one that you can sell with confidence and back that up for 5 full years. Who else does this but King?
One of the Ultimate lightweight, high performance hubs of the planet.
