I got the exact same type of bends in my Bianchi Volpe and kept riding it. I lasted a few more weeks 'til I had to make a hard stop. The frame and front forks flexed enough to let the front tire hit the down tube and instantly over the bars I went. If you do not want to debraze all the lugs, replace the bad rubes and rebraze it all stop riding it before you get hurt.
