OK, stock Trek 5200 with full Ultegra, bontrager race lite wheels, smallest frame they make - 50cm according to their sizing, really 54cm by other manufacturers measurements. Got it at Christmas, very smooth, very nice, loves to spin along. A huge difference to my Trek 1000. The new bike has shown some definite deficiencies in the engine that the previous bike hid. Done just over 2000km on her now.
Some say that this bike loves to climb, not sure about that, still have to push hard, not being a climber myself. Have heaps more confidence doing downhills and even the big difference in braking power has been really nice.
Best bit is that as well as feeling tight and strong and smooth I get off after a ride not feeling like I have been beaten up.
