Hey Folks! I am brand new to cycling and am primarily using it for commuting. I was using my wife's old Trek hybrid for awhile but then picked up a gently-used Domane 4.0. It came with a DuoTrap (not S, ANT+ only). I've been using my iPhone 5s as a cycle computer with Strava. I have an REI coupon and dividend to use, so I'm thinking about how to use this thing.

The DuoTrap fits in the frame, so I'd love to use it if possible, so here are my questions:

• Is there a lightning ANT+ adapter for the iPhone 5s?
• Does the DuoTrap S fit in the same slot as the DuoTrap?
• Are there any budget cycling computers (<$100) that will pass ANT+ data through to the iPhone 5s for Strava to use?

Thanks for any expertise you can offer!
