Sleek geometry of carbon fiber arms to pair with a Quarq DZero or DFour DUB power meter spider, builds a power meter that can handle the toughest of conditions.

TECHNOLOGY

• DUB

The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.

FEATURES

• Compatible with Quarq DZero DUB™ and DFour DUB™ power meter spiders
• Requires a SRAM DUB™ bottom bracket
