I had a Garmin Forerunner 201 for years (now a classic: http://www.outsideonline.com/1998626/garmin-forerunner-201) but it wasn't optimized for biking. The Timex Cycle Trainer 2.0 is a bike-specific computer, but it had two issues (for me). 1. the mounting clip does not mount it securely, so press a button to change screens and it pops out of the mount (awkward while riding!) and 2. I already had a mounting clip for the Garmin on my bike. enif had the Garmin mount designed (http://www.thingiverse.com/thing:167082) Thanks! I modified it by integrating a mount for the Timex with a more secure retainer wedge. I also added a version that mounts to a t-slot.
