Sram Red Direct Mount 12S chainrings

The Sram Red® groupset leverages a pivotal design innovation: smaller chainrings and a wider cassette range. This leads to smoother and faster shifting up front and more useful gearing for today’s riders. The new configurations improve cadence and efficiency while also delivering shifts that are crisp, clean and quick — every time.
