SRAM RED AXS AERO Powermeter Crankset | 1x12-speed | DUB | E1 - 50 Teeth

Effortless performance. Effortless perfection.

SRAM don't rest on their laurels. So when they found a way to make their lightest and stiffest crank even lighter, they went for it. A new optimized layup drops 29 g from their hollow carbon arms, and to stay on top of current fit trends SRAM have added their first carbon 160mm crankarm length option. Paired with an aerodynamic 1x chainring, this crank is ready to help you smash PRs. 

When you need the absolute best from your training data, the pro-proven accuracy and reliability of the RED AXS power meter is the way to go. Integrated into the chainring itself, it’s light, stiff and aero, accurate to +/-1.5% even as weather conditions change, and retains chains even when you hit rough stuff.

X-SYNC wide-tooth, narrow-tooth chainring technology provides maximum chain control

Note: A bottom bracket is not included and must be purchased separately.

Features of SRAM RED AXS AERO Powermeter crankset:

• Ultra-light, hollow carbon crank arms
• AXS enabled for easy monitoring and firmware upgrades
• Fully integrated power meter into a direct mount aero chainring
• Single chainring drivetrain simplifies functionality and reduces weight 
• DUB crank spindle for more durability and simplicity

Exogram

Hollow carbon construction starts in the crank arm and extends into the crank spider. It provides an optimal stiffness-to-weight ratio.

X-SYNC™

1x chainrings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfered edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. Accept no imitation.

DUB™ (Durable Unified Bottom Bracket)

DUB™ technology features a sophisticated bottom bracket design and a new crankshaft design. Together, they allow for a more unified approach to bottom bracket fit and a better seal against contamination. Now everyone can benefit from unprecedented durability.

AXS™

AXS™ is SRAM's integrated wireless platform for connecting electronic bike components with software. The SRAM AXS™ app allows riders not only to check battery levels, influence shifting behavior and configure controls according to personal preferences, but also to create maintenance schedules and update firmware.
