Sigma Rox 8

Bike computer with 3-channel wireless transmission
The SIGMA ROX 8.0 answers just about all the questions you could imagine. Besides measuring altitude, inclination and temperature, the newly developed digitally encoded 3-channel wireless STS (SIGMA TRANSMISSION SYSTEM) makes it possible to use several sensors, such as pulse measurement, speed and cadence transmitter, at the same time. Analysing the individual memories and total values on the PC, however, is only possible with the optionally available SIGMA docking station and software.

LED 20 lux

High performance optics and the latest LED-technology are the reasons for the bright-shining 20-LUX-light of the Sigma Sport Lightster. An additional safety-feature is the wide glare-free light view, which provides up to 20h homgeneous illumination. Light apertures on the side also increase visibility. The enhanced anti-skid pads of the proven click bracket offer perfect fit, even on oversize handlebars. The Lightster could be easily removed via slide-function to protect it against theft.
