But, after looking at your picture, I don't think your bike is a Specialized. I don't think they ever that kind of frame.

While FLYcrash is wrong about the frame failing catastrophically, the frame has failed. Putting bandaids on it or having it welded may void the warranty.

Since this is your transportation, think of it like you would a car. Would you continue to drive a car that had a broken ball joint or broken brakes? This is the equivalent, although cheaper to fix.
