Got my 2016 Giant Defy Advanced Pro 2 on order. Currently I ride a hybrid Specialized Sirrus and keep my Nexus 6P phone in my pocket while I ride using the Runtastic - Road Bike Pro app. I'll have to double check if both the speed and cadence sensors are installed on the new Defy or just the speed. But either way what I'm looking to do is to see if I can still use the same app with the sensors. If I need to switch apps that's fine too.

1. Anyone have a favorite cell phone clamp for their bike?
2. What apps have you used with your built-in Giant Ridesense?
3. Any heart rate monitor suggestions?

Tracking cadence and heart rate is new to me so I'm open to suggestions.
