It all depends on what you ride, street tgs, natrual or comps. Monty Kamels are competition bikes and can be cracked if rode street hardly. If your a smooth rider you could probably get away without cracking it for a while, but if your a Tgs basher it will last 5 minutes. Echo, Zoo, Czar, Adamant and Gu are all made by the same company 'Deng' and mostly all these frames can take a good bashing and afew dents before they crack. If your a new rider and not very smooth i suggest you get a Deng frame as it will last alot longer than the Monty. Also it all down to what geo you personally like so just try a few frames out and see which one you like best. Ryan
