Polar 450
Last week Polar revealed the little brother to their V650 cycling computer, the M450. The M450 has many of the same features of the V650, lacking mainly the mapping capabilities of the V650.
The technical specifications state 18 hours of battery life and 35 hours of memory. Polar remained with Bluetooth Smart only which may deter those with Ant+ power meters. However, at $169 ($199 with Polar H7 heart rate sensor), it is at a nice price point to compete with the Garmin 510 for those with BTLE sensors. Along with this announcement, Polar also gave a tiem frame (by the end of 2015) for auto sync between Polar Flow and Strava.
Slowtwitch is currently testing the V650 and plans to test the M450.
