The single pivot is back thanks to platform valving. Santa Cruz stopped production for the Bullit for a couple of years, reportedly to have time to make refinements to the bike, in 2007 Santa Cruz is reintroducing the new model to the market. A sturdy single pivot construction limits out of pocket repair costs as there are less places for problems to occur. The pivot rides in a 20mm axle on over-sized bearings (which have a lifetime warranty).
