Features1Highstrength 3K carbon fiber material. According to the number of monofilaments contained in the carbon fiber yarn, carbon fiber is divided into 1K, 3K and other carbon fibers. 3K carbon fiber is the best choice for highend headset covers! 2Using TC4 (GR5) titanium as raw material, rejecting secondary smelting or inferior materials with indeterminate quality. 3Lightweight carbon fiber design, TC4 titanium alloy material, PVD coating coloring, corrosion resistance and no rust. 4Titanium alloy has high strength, light weight, good performance, good mechanical properties, toughness. 5The screws are processed by an automatic thread rolling machine, the thread is dense and strong, and it is stable during the tightening process. It also enhances the overall smoothness and is colorful! 6Suitable for bicycles such as road bikes and mountain bikes, easy and convenient for installation, directly fitment.SpecificationConditon: Item Type: Bicycle Headset Cap SetUpper Cover Material: Carbon fiberScrewMaterial: Titanium alloyColor: As Pictures ShownUpper Cover Specification: Approx. 28.6mm/1.1inScrew Specification: Approx.
