Featherlight wheels for XC racers (or those who aspire to be) that are based on Shimano's lightest tubeless 29.6-mm carbon rim with hooks and straight titanium spokes, spinning on reliable, high-performance XTR hubs. The WH-M9200 wheels are not only the lightest ever produced in the XTR family, but they also feature Centerlock brake mounts and MICROSPLINE to complete the XC package.
