I posted this in another area but was told I may get better luck here..... I belong to many forums and a lot of times when a new guy comes on and asks a very general question he either gets ignored, hammered, flamed or all three. Lol. If you've read this far and want to give me your .02 I'd appreciate it. The budget is $500.00 MAYBE a little more. My Son will be 15 this year. He's around 5'9" now, I think he will top out at or close to 6'. This will be his second mountain bike, he has outgrown the first one. I'd like a general or all purpose mountain bike. I'm looking for your opinions on best bang for the buck bikes. Thanks in advance.
