This bike may be light but it isn't flimsy and it wasn't $ 5,000 either. I got a chance to build up my first Shimano 6700 Ultegra group on this bike and I am impressed with the shifting and braking on the new set. The hidden cables are new for 2010, something people have been wanting Shimano to do for years . Even without feather-wieght wheels this bike is about 18 lbs. 9 oz. , very good for a steel bike under $ 4,000. This one is going to the Monterey peninsula to be ridden on some of the most dramatic coastal roads in the western world.
