, a company best known for its sports-related technology
, has created a new on-board computer for cyclists hoping to improve their game, called the CS600. Supposedly developed with the help of six different teams that competed in last year's Tour de France, the advanced little monitor tracks your heart's performance (like if it's beating and how fast), bike speed, and altitude -- but that's just the start. All the data to the handlebar-mounted device is sent wirelessly over Polar's 2.4GHz W.I.N.D. technology (which we think might just be code for regular old WiFi), so you won't be worrying about pesky wires while you're speeding past all the bozos who didn't get one of these to train with.
