Sigma's BC 1009 STS is a smart wireless computer choice for every cyclist. Its diversity of functions make it an unrivaled bargain, too! Its easy to navigate big-numeral display is a joy to use. The integrated storage chip "remembers" your personal settings and total values even during battery change, which is announced by the low battery indicator. Plus, an optional second-bike sensor is available.
