I crashed my brand new TREK 4400 on my first ride around the town. It had rained an hour before the ride, pavement was slippery, and I took a nice slide on the pavement when trying to jump up a curb with my brand new RST fork. The front wheel rebounded, and off I went, of course, in front of a dozen of people waiting for a bus. Scrached that RST fork, and I still haven't replaced it, although it barely holds itself together after 2 1/2 years of riding.
By the way, I crashed with my previous bike (TREK 800) on one of the first rides as well. A pedal went off, because some ***hole in the shop had not tightened it enough. I avoid that shop ever since.
