Vändad võimsuse mõõtjaga SRAM Red 1 D1 DUB Quarq Aero 50T

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.

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.

Non-aero chainrings can be installed with a single tool, making gearing changes a breeze.

TECHNOLOGIES

AXS - AXS is SRAM's bike component integration system that connects electronic bicycle components and software. The SRAM AXS app allows riders to see battery status, change component behavior, personalize controls, get maintenance reminders, and update firmware.

X-SYNC - SRAM 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 chamfer 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 integral part of the SRAM 1x drivetrain. Accept no imitation.

EXOGRAM - Our hollow Carbon Construction starts in the crank arm and extends into the crank's pider, maximizing the stiffness to weight ratio.

DUB - The relationship between bottom bracket spindel 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.
