XCADEY XPOWER-S Gen2 Power Meter — SRAM 8-Bolt 107 BCD

XCADEY XPOWER-S Gen2 Power Meter — SRAM 8-Bolt 107 BCD — Features & Benefits

• True Spider Power: measures combined left+right power at the spider for accurate, repeatable numbers — not an estimated single-side double.
• ±1.0% Accuracy: eight high-precision strain gauges with intelligent temperature compensation for stable readings in heat and cold.
• Full Metrics: power, cadence, left/right balance and pedalling smoothness, across 0–2500 W and 30–220 rpm.
• Dual Protocol: ANT+ and Bluetooth pair with virtually any head unit plus iOS/Android apps at the same time.
• 350-Hour Battery: long life from a 150 mAh cell, topped up via a magnetic USB blind-plug port in about 3 hours.
• All-Weather Build: IP67-rated and rated to operate from −10 °C to 50 °C.
