Trek Domane 5.9 Dura Ace.

I would be interested, my Wife uses her iPhone to track rides.You should start a thread on the Wahoo devices once you use them a few times. It would be interesting to know just how well they work on preserving battery life on the iPhone when both the GPS and BlueTooth are activated and being used. If nobody else is interested, I for one would be.
Oh yeah, my lovely wife got me the same camera, helmet strap and bar mounts... Gotta get out and dirty up the Santa Cruz Superlight now....
