The name says it all, the 2001 Hoffman Bikes Dirty 1 Thirty Star Series is made of 100% 4130 Cromo and can get as dirty as you want it to. This bike rules! As many dirt jumpers/street riders have figured out, the D130 is at home in the dirt or the air. It's common to hear from current D130 pilots, "This is the most stable bike in the air I've ever ridden".
