Description
SRAM RED AXS Power Meter – Precision Redefined for Road Cyclists
Engineered for elite road cyclists seeking real-time power analytics and seamless electronic shifting, this double-chainring system combines Quarq DZero power measurement with X-Range™ 12-speed gearing for unmatched control across gradients.
✨ Key Innovations
• ±1.5% Accuracy: Climate-resistant torque sensors deliver lab-grade precision during interval training or endurance rides
• X-Range™ Technology: 46/33T chainrings provide 13-tooth progression ratios (equivalent to 11/25 cassette) for smooth cadence transitions on climbs/descents
• Integrated Design: Power meter embedded directly into aluminum chainrings eliminates bulky sensors (saves 85g vs traditional crank-based systems)
• Dual-Sided Metrics: Independent left/right leg power analysis identifies asymmetries during FTP-building workouts
🚴 Road-Specific Engineering
– Compatible with SRAM DUB™ bottom brackets (sold separately)
– 45mm chainline optimized for disc brake road frames (130/135mm rear hub spacing)
– Carbon fiber crank arms reduce rotational inertia by 18% compared to alloy competitors
