Wicked vs Wicked Lite
The Lite is a later iteration of the original Wicked, which started in 1987.
The Lite, which started in about 93 or 94 (can't recall without checking the catalogs at home) had a lighter tube set (based upon the 10th IIRC), top tube cable routing and a "regular" bottom bracket.
The Wicked has always been my fave Fat, and my Lite is probably one of my favorite bikes to ride.
Doug has a very nice grey one too.
