Cyclo-Computers

Sigma Sport's Cadence Power Magnet is the correct replacement magnet for any Sigma Sport computer featuring cadence (computers sold separately). It attaches to your crankarm with zip ties and double-sided tape (both included).

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.
