StemCAPtain was founded in the summer of 2007, in the beautiful Rocky Mountain foothills of Boulder, CO. Two friends, Graeson “G-Train” Lewis and Mike “Jack-7″ Hogan, might not have agreed on what a good all-in poker hand is, but they both agreed the stem cap on their bike was destined for a higher purpose. With a common distaste for watches and cycle computers, they set out to put a clock in the place of the stem cap.  Throw in Mike’s mechanical engineering background, Graeson's bike knowledge and computer savvy, plus a little bit of creativity from the both, and presto, the original StemCAPtain was born.
