Sigma BC1606L

This little square comp is basic, but what it does it does well. Head and transmitter mount simply and easily with ‘O rings’ that make initial fitting to either stem or bar, and subsequent switching between bikes, easy.

Once you’ve knocked it out of the default German language setting, getting it going is easy and intuitive, and the sensor is powerful enough to run from the back wheel if you want.

The four (two top, two bottom) control buttons are big and obvious to use even with gloves on. Little touches like automatic bike 1 or 2 recognition, low power warning and an essential information save, that stores settings when you change the battery, are thoughtful.

There’s no HRM functions, though, and the cadence sensor equipped version is £10 extra.
