Sram Red 1X D1 Quarq Road Powermeter Dub: Black 170Mm - 50T Aero

In certain disciplines, the single-ring drivetrain reigns supreme. Championing simplicity, strength and durability, the SRAM RED 1 AXS™ power meter meets the demands of triathletes, time trialists and cyclocross racers. The power meter features improved aerodynamics thanks to direct mount aero chainrings with fully integrated power, and the tighter gearing range is perfect for racing and flatter terrains.

THINGS TO REMEMBER

• Single-ring drivetrain simplifies functionality
• 48 and 50t variants have fully integrated power into a direct mount aero chainring
• 36-46t variants have spider-based power
• Chainrings can be easily changed without requiring recalibration of the power meter
• Power readings are accurate within +/-1.5% and aren’t affected by climate conditions during a ride
• Power balance measures left and right legs separately
• SRAM X-SYNC™ wide-tooth, narrow-tooth chainring technology provides maximum chain control
• Laser-etched chainring finish is more durable
• DUB™ bottom bracket adds durability and simplicity
