I was in Performance the other day and saw a bike that looked a lot like my Overdrive Comp, except it had a black frame and was called the Overdrive XC. It doesn't show on DB's website and is listed as a 'Performance Exclusive' on their website.

Both bikes are spec'd identical from what I could tell, except for X7 shifters and X7 rear derailleur on the XC model for roughly $40 bucks more than the Comp (depending on seller).
