Being fed up with those mechanic tire-pressure gauges, I decided to get a digital one.. which instantly made me go foul when finding that this freaking thing won't fit the stem of the front tire due to the wheel's spokes and brake-disks are in the way. An easy fix; get a 45-degree, or better yet, a 90-degree valve-stem. The only problem for me was to remember to do this when I put on a new front tire.. (it took me almost a year until I finally got to use my digital tire gauge ;^)
