Cateye V3N (CC-TR310TW) Wireless Cyclocomputer

The redesigned V3n brings greater reliability to our most feature-packed computer. 2.4Ghz digital wireless technology eliminates interference and crosstalk, tracks speed, cadence, and heart rate. 

The all-new detachable fabric HR sensor is designed to be more comfortable than tradition chest straps. Two programmable heart rate zones with an audible alarm help you keep track of your workload along with displaying your current, average, and max heart rate data.

It’s everything you could possibly want in a slim, easy to read package, plus a backlight for those early morning adventures.
