Cane Creek brought threadless headset technology to the bicycle industry in the early 1990s, beginning the revolution in fork and head-tube innovation. We held the patent for nearly 20 years, and during that time licensed the technology to qualified manufacturing partners around the world. Many of these partners elected to etch the “Cane Creek” name and the patent number on the top cover of the headset, in recognition of the license. Regretfully, due to the sheer volume of headsets produced, we are unable to stock spare parts nor assemblies from these licensed headsets. For direct replacement, please visit your local bike shop, or contact us at 800-234-2725 and we can help you identify an equivalent Cane Creek product that will fit your bike.
