SRAM RED D1 DUB 172.5mm 50/37T Crankset
X-Range™: Smoother and faster shifting is now possible through SRAM RED®, their crankset leverages a pivotal design innovation: smaller chainrings and a wider cassette range. Get faster access to 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. DUB™ The relationship between bottom bracket spindle and bearing is the core of DUB™ technology. It’s where stiffness meets durability. SRAM took it a step beyond conventional thinking and made everything simpler—and better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this clear system approach that equals better drivetrain performance.
