sell sell sell... if a bike hasnt been ridden in a few months.. its time to sell it.. unless you want to be like the suburben couple thats got some dusty matching treks in the garage.. ive never regretted selling a bike.. ive sold a lot.. if you do regret it .. then buy a new one.. although it might be a nice bike.. i highly doubt you'll miss a 2000 marin if you havent missed it enough to put it back together from 2 years ago.. the last bike i sold was a marin mtn bike.. and ..nope.. its not missed and im sure its having more fun..
