The steelhead is a tank. One of my friends put a jr.t on it and hucked off some huge sh#t. My other friend had an urban set up. He did a lot of stairs and docks to flat. Both are still going strong. The frame is steel, there for really heavy and strong (It is marketed as a freeride/dirtjump/urban frame). I have never in my life seen or herad of someone breaking one of these.
