XCADEY XPOWER-S Gen2 Power Meter — SRAM 8-Bolt 107 BCD
The XCADEY XPOWER-S Gen2 Power Meter — SRAM 8-Bolt 107 BCD is a spider-based power meter that measures total (dual-leg) power directly at the chainring spider, with a claimed ±1.0% accuracy. Machined from AL7075 with 8 high-precision strain gauges, it transmits over ANT+ and Bluetooth to your head unit and phone, recharges over a magnetic USB port, and mounts to SRAM 8-bolt 107 BCD direct-mount cranks. Backed by a 24-month warranty.
