SRAM RED XPLR Powermeter Crankset

The SRAM RED E1 XPLR Powermeter Crankset is SRAM’s top-tier gravel drivetrain solution, combining 1x simplicity with precision power measurement. Built for elite gravel racing and data-driven performance, it delivers dual-sided accuracy, ultra-light carbon construction, and unmatched drivetrain integration across the XPLR ecosystem.

Key Features & Benefits

Dual-Sided Spider-Based Power Meter
Measures left and right leg output independently, providing accurate total wattage and balance metrics for high-level training analysis.

±1.5% Accuracy with Temperature Compensation
Maintains precise readings regardless of environmental conditions, ensuring consistent data across long gravel rides and changing climates.

Thread Mount Chainring System (Major Upgrade)
Features removable thread-mounted chainrings, allowing riders to replace worn rings or change gearing without replacing the power meter, a key advantage over previous integrated designs.

Wide Chainline for Gravel Optimization (47.5mm)
Improves tire clearance and drivetrain alignment on modern gravel frames, resulting in better chain retention and reduced wear in rough terrain.

Ultra-Light Hollow Carbon Crankarms (E1 Generation)
Refined carbon construction reduces weight while increasing stiffness, delivering efficient power transfer and responsive ride feel.

1x X-SYNC Chainring Compatibility
Designed for narrow-wide X-SYNC chainrings to maximize chain security and quiet operation without a front derailleur.

DUB Spindle System
Enhances durability and simplifies compatibility across bottom bracket standards while maintaining optimal stiffness and reliability.
