Technologies

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.

Carbon Tuned™
Strength and stiffness where you need it, lightweight like you want it. Proprietary Sram carbon lay-up design increases thickness and stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength.

Chainrings fixing bolts included.
Bottom bracket not included.
