The K4 wheelset features many of the same technologies that make the K1 such a formiddable force in the MTB wheel market, but it's been scaled down a little to make it more of an affordable package. The rims have been built up with UD Carbon Fibre and feature a 25c internal width but can still have the hookless technology. The hub bodies have been made with AL 7075 T6, which has been CNC finished and SKF low-friction bearings. The hubs are available in regular, boost and even compatible with the Rock Shox RS-1 Fork. A 24/24 spoke pattern with straight pull, double butted, stainless steel spokes coupled with AL 7075 nipples marries the rim and the hub for high strength. **These wheels are covered by a Crash Replacement Scheme offered by Chicken Cyclekit.
