Sram Red Crank Set AXS 50/37 DUB 175mm

The SRAM RED AXS power meter is a huge step forward in power meter design, giving riders the gearing they truly want and need. Shifting performance has been optimized by moving the range from the front of the drivetrain to the back, and creating a consistent 13-tooth gap across all variants of chainring duos. The crankset is designed specifically for electronic shifting, with Quarq s premier DZero power measurement technology fully integrated. X-Range gearing technology gives you more range and a smoother gear progression, so you re always in the right gear Power meter is fully integrated into the chainring set ANT+ and BLE Power balance measures left and right legs separately Power readings are accurate within +/-1.5% and aren t affected by climate conditions during a ride Integrated chainring design significantly reduces weight Unique chainring shape results in a lighter weight, stiffer, more durable crankset Carbon crank arms and aluminum chainrings are lightweight DUB bottom bracket (not included) adds durability and simplicity 45mm chainline Item Specifications BB Included No Chainline/Hub Compatibility 130 Hubs Chainline/Hub Compatibility 135/142 Road Disc Hubs < 415 mm Chainstay Chainring BCD Direct Mount SRAM Color Natural Carbon Crank Intended Use Road Crank Length (mm) 175 Defined Color Carbon Drivetrain Speeds 12 Number of Chainrings Double Pedal Spindle 9/16" Rings 50/37 Spindle Interface Type SRAM DUB
