Need advice on bike

There are too many other important considerations that are not listed here in order to determine a value. For starters, this is a road bike with "clip on" triathlon bars. Are you looking to compete in triathlons? If so, going with a tri bike would be a better value for you. What components does the bike come with, and what wheels?

Most likely the components are Campy or Shimano. Both great gruppos. However, Campy is Italian, a pretty expensive to maintain. This bike comes with a triple crank, meaning three chain rings attached to the crank which are typically used by beginners. On a group ride, it is fairly unusual to see a triple crank. Once you have a few hours in the saddle, you will realize that a triple crank merely represents extra weight and you will probably never use the small chain ring in the front.

Bianchi is a very well respected Italian frame maker that has been around forever. Depending on the components, I would say the bike is worth somewhere between $600 and $1100. If the components are entry level, I wouldn't pay too much for it.

BTW, if the components are Shimano, they offer several groups: Starting at the bottom, they offer Sora, Tiagra, 105, Ultegra, and Dura Ace. They put Sora and Tiagra on beginner bikes, 105 and Ultegra on mid level bikes, and Dura Ace on top of the line road bikes.

Hope this helps.

If it is too big or small for me I wouldn't buy it at almost any price.

It's interesting that the owner shows it on a trainer. Is the front wheel included with the bike? Do you know if this size bike will fit? There's not much else to say without knowing specifics about which Campagnolo group is on the bike, what wheels are on the bike, what condition (as seen in person) the bike is in.......... Also, IMHO the tri-bars and computer add no value to the bike. "Ride-tuned" is just marketing spiel. It does have a nice seat post, one of the best, but it doesn't add a lot of value to the bike.
