Sigma Power LED Evo Pro

Chucking out the most powerful, penetrating and wide-reaching beam on test, the Sigma is a serious light. Breezing through all our ride tests, including the off-road mission, even at its lowest light output it’d be more than adequate for most road-riding situations. Bar mounting is simple and, a better option off road, it can also […]

Sigma BC 1609 STS Cadence

In the looks department the Sigma is head and shoulders above the competition. Both the speed and cadence sensors have a stealthy mean appearance, and the head unit looks genuinely cool and wouldn’t look out of place on a carbon mega bike. The sensors fit easily with a couple of zip ties, and the head […]

It interfaces with a PC via a USB connection and software supplied for ‘easy’ analysis. In […]

Sigma has always had a solid reputation for decent easy-to-use computers and this full-function squarehead is no exception. Paying nearly £100 gets you chrome sidestripes and crisp detailing all round, as well as a massive book of instructions. ‘O’ ring installation is easy and repeatable on different bikes without the need for extra zip ties. […]

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 […]
