This is the information age, so your bike's computer should be, ahem, up to speed. Bontrager's next-generation Node Digital Computer lets you train smarter with speed, cadence, programmable heart rate zones, wattage and even a nutrition reminder on one easy-to-read screen so you don't have to play with buttons while you ride. Node computers can receive data from 3rd party power devices that are ANT+ compatible like SRM cranks and PowerTap hubs, too.
Fits on most handlebars and stems.
Node computers require ANT+ sensors (sold separately).
