The bike comes with ride sense so you can use an ANT+ computer using GPS. When I got my Propel, I didn't get into all that. I just got a cheap Cateye wireless so I can view the speed and distance modes. The readout is plenty big for easy viewing. Were your minor adjustment problems mechanical or fit related? I keep my phone in a plastic baggy in one of my jersey pockets. I have no interest in seeing it on a ride. Enjoy the new ride!
