Speed Tuned ST300 Series

The Speed Tuned ST170/300 hub offers a redesign of the original Speed Tuned D series hub shell, saving weight and allowing for convertible end caps and freehubs, as well as an improvement in bearing quality. The freehub engagement offers the same rock solid system from the original D-Series hubs, meant to offer a reliable engagement that will stand up to the considerable strain of today’s 1x drivetrains. The new Speed Tuned ST160 / ST300 hub set is available in multiple end cap configurations and can be converted to run either Shimano freehub bodies or SRAM XD drivers.
