The specs are below. I'm 5'10, so size wise it sounds good. I had been planning on getting a Bianchi Volpe/Axis, Specialized TriCross Sport, something along those lines, to use as a training bike/commuter. This seems like a decent bike build, and the price is right

.

I just finished building this bike up, it runs very smooth, its light and quick. I'm 5'11" and the bike fits me
