SRAM RED AXS Power Meter Crankset 48/35T 167.5mm – Lightweight & Accurate

The SRAM RED AXS Power Meter redefines precision and performance for road cyclists seeking an edge in training and competition. Engineered to seamlessly integrate with SRAM’s electronic drivetrain systems, this advanced power meter combines cutting-edge technology with race-ready design to deliver unmatched control and data accuracy. Whether tackling steep climbs or accelerating on open roads, its X-Range gearing system ensures a smoother transition between gears while expanding your low-end torque capacity—a game-changer for riders navigating varied terrain or chasing optimal cadence efficiency.

At its core lies Quarq’s DZero power measurement technology embedded directly into the chainrings, offering real-time insights that are both highly accurate (within ±1.5%) and immune to environmental interference like temperature fluctuations or humidity. This dual-sided measurement tracks left/right power balance separately, empowering athletes to refine their pedaling technique and prevent muscle imbalances during intense training sessions or long-distance events such as gran fondos or triathlons.

Constructed from lightweight carbon crank arms paired with durable aluminum chainrings (48/35T), the RED AXS balances stiffness and minimal weight—critical for maximizing wattage transfer without sacrificing agility. The 45mm chainline ensures precise chain alignment across all gears, while its Direct Mount SRAM BCD design simplifies setup and enhances durability compared to traditional spider-based systems. Compatible with 12-speed electronic drivetrains and road disc hubs (130mm/135mm/142mm), it’s tailored for modern road bikes with chainstays under 415mm. A natural carbon finish complements its aerodynamic profile and sleek aesthetic favored by performance-oriented riders.

Why Choose SRAM RED AXS Over Competitors?
| Feature | SRAM RED AXS AXS Power Meter | Competitor Models (e.g., Stages EVO / Garmin Vector 3S) |
|————————|——————————-|——————————————————-|
| Power Measurement | Integrated dual-sided DZero tech | Spider-mounted sensors (single-sided) |
| Gearing Innovation | X-Range expands low-end torque | Traditional gear ratios |
| Weight | Ultra-light carbon/aluminum build | Heavier due to external sensor mounts |
| Accuracy | ±1.5% precision + climate-proof | ±2% accuracy; may drift in extreme conditions |
| Compatibility | Full SRAM AXS ecosystem support | Limited compatibility with electronic shifting systems |

Designed for racers and endurance enthusiasts alike, this crankset pairs effortlessly with your favorite pedals (9/16″ spindle) and offers precise 167.5mm crank length adjustments to dial-in your riding position. While requiring a separate SRAM DUB bottom bracket for installation, its streamlined architecture minimizes bulk without compromising strength—ideal for time trials or century rides where every gram counts.
