Today, Chris King Precision Components announced the discontinuation of its FusionFiber wheels for the foreseeable future, but assured customers that lifetime warranties remain valid.
Chris King is the latest brand to come forward with a rider support solution following the unexpected shutdown of Utah-based CSS Composites, the creator of the recyclable FusionFiber carbon rims used by brands such as Chris King, Revel, Bontrager, Atomik and Forge+Bond.

We are heartbroken for the people who lost their jobs and the vision that won’t now be realised. We never like seeing a U.S. manufacturer closing their doors.”

Partner brands say they received little or no warning before the closure, leaving them scrambling to establish their own rider support programs.
“The most important thing for our riders to know is that…
