sorry for not stating intended use upfront, thanks for the input.
just got off the phone with the guy at the lbs. asked him about the bump, says he has it but that i'm too old (35) to be riding bmx, says i wont be happy on anything other than a 26" with gears. says hes conserned for my knees, i'll agree i should consider my knees but come on, i think hes trying to get me into something that pays him a little more. i for one don't like the look or the hassel of multi gears, just more to go wrong and leave me walking out on the trail. guess i'll be looking els where. thanks all
