I am ordering my first mountain bike within a week (after I go watch a race and see what everyone is riding). I can't decide between the Dirtbag or the Stinky. Price is an issue, and I do realize that there is six or seven hundered dollar gap. Because it is my first bike I am wondering if I will be able to tell the difference at first. I was thinking of buying the Stinky then upgrading it every couple of months as I get better, i.e. buying better fork, better drivetrain, etc. then transfering it to the Dirtbag frame. I was wondering if anyone has done this or recommends doing this. I really want a bike that I can pedal around the block during the week than beat the **** out of it during the weekend. If it helps I am 6'-0" at 175 lbs. and live in SoCal. Any advice would be greatly appreciated.
