I know i may be a little premature on this but I am calling this bike out as Trail Bike of the year for 2011. This is based solely on personal opinion here. The 2011 Cannondale RZ One Twenty 2 is an amazing bike with 120mm of suspension travel via the new lightweight forged lefty and a Fox RP2 in the rear. At $2500 this bike is kitted out above and beyond it's competition; XT shifters and rear derailleur, Hayes Carbon Stroker dual piston brakes and a smoking hot paint job.
I am seriously thinking about adding this bike to my quiver to use for longer enduro races and for riding aggressive terrain that leaves my 29er feeling like a school bus. The balanced geometry and extra travel that this bike offers will be sooo beneficial for races over 4 hours on rougher terrain. Come by the shop to see the bike in person, it really is amazing.
