Sigma BC 1009 STS computer review
This top-quality, high-visibility downloadable wireless unit is great for drop or flat-bar bikes. The setup instruction Bible is ruthlessly efficient in typically Teutonic style so figuring it out is easy. The rock-solid sticky back mount will work with standard bars and flat bars if squashed, but won’t work with stems or top tubes.
The sensor fixes with a rubber band or zip ties, the clip-on magnet is super-tenacious, and everything has a really good-quality feel. Current speed and clock are clearly displayed so you won’t miss your tea. An easy to press bottom button scrolls the secondary menu of speed, double decimal-point distance and timer. Decent-sized digits and title bar keep you on track even when your blood sugar’s low.
