Sigma Sport Cadence Disc Pedal Magnet
$6.99
The cadence magnet pedal insert is designed for tight installation situations. The principle is simple, yet space-saving: the power magnet attaches to any steel pedal spindle by magnetic force alone. From there, it triggers the cadence transmitter with each crank revolution.
Sigma Sport R2 Duo Speed/Cadence Combo
$59.99
The R2 DUO Combo transmitter for speed and cadence transfers data to both ANT+ and Bluetooth-Smart-compatible devices. This makes it possible to simultaneously send all important data to the ROX GPS 11.0 and a smartphone using any compatible app. All of your data gathered through a single transmitter eliminates the need for multiple devices.
