I don't know about that...my buddy uses a .243 for dj and ha has a 100mm Gold Label II on it, and he has 2 wrinkles in the Top tube after only 3 months, and .243 won't return his calls. I would say if you're gonna run 2x the travel, you're probly gonna have at least 2x as many problems...And no, we don't hate cuz we like bmx, we ride so that the geometry is conducive to flow. Get a hardtail, set it up with a inexpensive 3-4" fork (or whatever the frame is designed around) until you have enough. Matter of fact, I have a couple frames and forks, always down to help riders out!
