The question is simple: are you tough enough for the Free? Possessing an incredible 215mm of active rear travel, 150 mm thru-axle rear wheel, 1.5" head tube, ISCG05 chain guide mounts, and completely over-built everything, there's nothing the Free can't handle. If you choose to spend all day going straight down, or throw on a triple and get your climb on, the Free will, without a doubt, set you free. If the 4X is the Charles Bronson of our bikes, then the Free is very definitely the Robocop, only with more travel. *Important note: We are sold out of all VP-Free frames right now through the rest of the 2007 season. Next available production batch will be the 2008 model expected mid 2008. You may be able to find a 2007 VP-Free in stock at a dealer now, but there will be no more new orders being accepted through our Sales Dept for the remainder of the 2007 season.
