Cycling bike: 800$ (Not before march 1st)

I'm sad to sell my amazing, hand-made, Italian bike I brought here directly from the "bel paese" one year ago. I would like to keep the bike into Stanford hands.

Some specifics:

*Aluminium frame with carbon fiber parts (forks + handlebar)
*Shimano 105 brakes
*Shimano F-50, compact, 50-34 chainwheel
*Very light, ideal for amateur cycling on the hills

Can't sell it before March 1st cause it's my only mean of transportation.
