I have a cell phone mount on my handlebar, and I do like it up there. I usually ride with Strava open and tracking me. I also often ride with Pandora radio, and I don't wear headphones, and keeping the phone up on my handlebar means I can hear the radio without having it cranked up so high as to annoy other folks.

Regarding your tires, they look neat:

Nice meaty 39mm when installed.

Amazon has the folding bead version (probably the most desirable, with its better casing) for 30 bucks, and the wire bead version for 22 dollars. Great value!
