Cyclo-Computers

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's universal computer mount features a wired speed sensor, so you can use your Sigma cyclo-computer on a second bike. This kit comes with O-rings and a spoke magnet.
