Magene Speed/Cadence Dual Sensor

The S314 is a compact, third-gen sensor that switches between speed and cadence. It's 12% lighter and 10% smaller than before, with a double-secured anti-loss strap. One mode at a time, so use two sensors for both.

Highlights

• Speed or cadence mode
• ANT+ and Bluetooth
• 7.7 g with battery
