We use precision engineering to make lightweight, strong, and durable bike headsets in EC, IS, and ZS options and use a triple-sealed system to keep out the elements. These are designed for mountain bikes, gravel bikes, fat bikes, commuters, e-bikes, and road bikes with non-proprietary stem shapes or integration. Our Premium Headsets come with a lifetime warranty, are made with stainless steel bearings, and have three top cap height options. The Performance Headsets are made with many of the same materials as our Premium Headsets, but instead come with black oxide-coated chromium steel bearings, a low-profile top cap, and are covered by a one-year warranty. All of our headsets come in a wide variety of colors to keep your bike (and your style) looking fresh.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\" data-mce-fragment=\"1\" data-mce-style=\"text-align: left;\"\u003e\n\u003cspan style=\"font-weight: 400;\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\" data-mce-fragment=\"1\" data-mce-style=\"text-align: left;\"\u003e\n\u003cspan style=\"font-weight: 400;\"\u003e\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\" data-mce-fragment=\"1\" data-mce-style=\"text-align: left;\"\u003e\u003cspan style=\"font-weight: 400;\"\u003eYou'll also see the GeoShift Angle Headset.
