Hi all I am just looking for advice on the Gary Fisher Nirvana. I have always enjoyed casual greenbelt style riding- maybe a little dirt/gravel/sand trails too - but with gas prices rising I am trading in my '89 Dodge Spirit for a comparably priced ($500 or less) bike. I previously owned a 2003 Diamondback $240 bike which was stolen. This bike served me fairly well but was slow, had sloppy brakes, and joints which tended to strip easily. I am a small man (5'10" 160#) and do not put any strain on bikes- I would just appreciate hearing any reviews or advice.
