SRAM RED E1 XPLR Crankset

The SRAM RED E1 XPLR Crankset is SRAM’s top-tier gravel crankset, purpose-built for 1x simplicity, maximum efficiency, and race-level durability on mixed terrain. Designed around the XPLR ecosystem, it delivers ultra-light weight, exceptional stiffness, and optimized chain retention for aggressive gravel and all-road riding.

Key Features & Benefits

1x-Specific Direct Mount Chainring System
Designed exclusively for 1x drivetrains, the direct mount interface improves stiffness and simplifies chainring swaps, delivering efficient power transfer and streamlined setup.

Wide Chainline Optimization (Gravel-Specific)
The wider chainline improves tire clearance and drivetrain alignment on gravel frames, ensuring better chain retention and reduced wear in rough conditions.

Hollow Carbon Crankarms (E1 Refinement)
Updated carbon construction reduces weight while increasing stiffness, resulting in more responsive power delivery on climbs, accelerations, and rough terrain efforts.

X-SYNC Narrow-Wide Chainring Technology
Aggressive tooth profile enhances chain retention without the need for a front derailleur, providing quiet, secure drivetrain performance over rough surfaces.

DUB Spindle Interface
Ensures broad bottom bracket compatibility, improved bearing durability, and consistent stiffness across a wide range of gravel frames.

Optimized for 13-Speed XPLR AXS Systems
Fully tuned for SRAM’s 13-speed XPLR drivetrain, delivering smooth shifting and efficient chain engagement across wide-range cassettes.

Power Meter Upgrade Compatibility
Compatible with SRAM’s spider-based or spindle-based power meter systems, allowing riders to add performance tracking without replacing the entire crankset.
