Inside, diamond-polished bearing races and stainless-steel ball bearings minimize rolling resistance, while high-tech seals keep out water and dirt for maximum durability. This hub also features tool-free bearing adjustment for easy maintenance plus a light and sturdy aluminum/steel quick-release skewer.
