Welcome to the forums FE11244. Nice looking Bianchi.

I can't tell anything about the tubing from the decal but it looks to have a chromed chainstay and chroming under the paint so I agree this not a lowend bike. It is an OK middle of the road bike and certainly worth a little attention.

First of all if the shop did a proper tune up and the braking is not to your liking go back and describe what you are having trouble with and see if perhaps they can offer some pointers. Also I see a lot of dirt on the front brake so were these pics before or after the tune up? Did the shop replace the brake pads? A new set of pads may improve your stopping, as well as cleaning the rims with a little oil free nail polish remover or rubbing alcohol.

Try nail polish to match the color.

As to the gearing there are two easy things you can do. As mentioned a wider range freewheel will give you a lower climbing gear. Depending on the make and model of your crankset you might be able to change the inner chain ring and reduce your overall gearing a bit.

Great looking Bianchi, I always wanted one that color but when I see one the timing is never right.
