Sram Crankset Red D1 (Bb Not Included): 172.5Mm - 50-37T

FOR TREK FRAME WITH BB90 and FRAMES WITH ITALIAN THREAD – GXP INTERFACE (NOT DUB COMPATIBLE)

The SRAM RED® crankset 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.
