Can it be done or has it been done running a 30 with the kewl metal bolt on kit? I've tried to contact them with this question. I know of one guy that uses their trees with a 26 who has had no problems. All the shops say stay away from them. If there working why isn't the word getting out more? I'm just trying to get the right answers dont want to chop up a brand new bike if I dont have to.
