I got the front tube tire fixed: job was done quickly and apparently ok for 22 $ with taxes.
The waiters were really unkind, I' writing this as I felt really bad in the shop (i don't usually write reviews!).
After two days my bike was on ground again, I went there to ask forum the mechanic had check for needles and stuff when changing the tube; again found very bad treatment. I bought a new tube and instruments for 12 $ and I fixed it my self. I then discovered a place called cyclab in Princeton: much better!! If you need to buy great stuff I don't know, but whatever place might be better than that!
