I've really been wanting to get into more riding and I've been debating getting a new hybrid bike (Trek DS or Giant Roam). Currently I have a mid 90s Diamondback Traverse MTB that I haven't ridden much in the last few years. It is in beautiful condition but has mountain tires. I figure I can change those out to a more road friendly tire and maybe upgrade to some nicer grips, possibly change out the fork with lockout suspension. I'm sure I'd probably find something else to do once I got into it, but those are the things that I can think of right off hand.
Most of my riding is on pavement or dirt roads but would like to get into more trail rides. Since I've never really "upgraded" a bike, is this a smart move to do or should I just look to sell it and get a new DS or Roam (or other)??
