I am riding the MS150 this year and have been ogling a road bike for some time.  I would love to speed through the hills and turns on this in lieu of a K2 mountain bike but 1 bike > no bike.  If you are in the market for a cool looking bike with some nifty features this bike is pretty cool for the money.  Fully-butted alloy frame, carbon fork, Shimano Ultegra 10 speed shifters, Shimano 505 clipless pedals, Shimano RS-10 Rims 14g with black spokes and wrapped with some Michelin Dynamic tires.  BALLER!  Really a nice bike, looks bitch, and super light weight.
