Pictured here is Dean Tracy at the Six Days of Amsterdam 10/24/2009 aboard Ground Up #203. Dean had a solid week including two wins and many solid performances against multiple World Champions. Dean has ridden Ground Up bikes to two National Championship wins and multiple US and International Grand Prix victories.

" International racing demands a huge amount from track frames, and Eric's bikes deliver. I need every advantage I can get, and together we've tweaked these bikes to world-beating levels of performance. You just can't get this level of custom geometry, ride tuning and mad-scientist innovation from a stock carbon or aluminum bike. "
