Sram Red D1 DUB Crankset 46/33T 172.5 black 03015281

The SRAM RED® cranks use a key innovation in design: smaller chainrings and a wider cassette range. This leads to smoother and faster gear changes at the front and more comfortable gears for modern cyclists. The new configurations improve pedaling rhythm and efficiency while providing clean, sharp, and quick shifting—every time.
