Sitting at the top of the heap in its bike computer range, this GPS possesses a huge screen with a  high-resolution display giving you real-time ride stats and receiving incoming texts, calls, and notifications from your smartphone so you can stay connected as well as turn-by-turn navigation. The Mega XL differs from the Mega C by featuring a bigger display that can be situated both vertically and horizontally, and it also has a longer battery life that runs for an unheard-of 48 hours. Add in the additional Flow heart rate and cadence sensor, Forward mount, and a trick caring case and you have one of the coolest cycling computer packages to hit the market.

The Mega XL can simultaneously pair with Bluetooth Smart or ANT+ enabled power meters, heart rate monitors, and speed or cadence sensors, showing you real-time stats such as calories burned, elevation, distance, speed, laps and lap averages, and the grade of your ride. The free Ally V2 smartphone app also allows you to receive incoming texts, phone calls, and message notifications to keep you connected if you choose, even if you're blowing off some steam and trying to disconnect. The GPS/Glonass system provides turn-by-turn navigation, offline maps and re-routing, and custom route building to help your ride stay on track from start to finish.
