Sigma's digitally coded BC 1909 HR is kind of like riding with a laptop on your handlebars, only this computing powerhouse comes in an amazingly small package. You get all the classic features of a wireless bike computer plus a heart rate monitor and wireless cadence! You can read 4 current values (cadence, heart rate, speed and another optional function) simultaneously so you spend less time scrolling through features and more time riding! Plus, the 1909 even records the amount of calories you burn during your workout!
