A tale with a moral attached, from my dim past.
In the 1990's I raced MTB cross country (too chicken to do downhill and 4X hadn't even been invented then). I started by buying a mid-range hardtail Marin, returning it after 3 weeks to get the top of the range one(Pine Mountain). I rode that bike, day in, day out, raced it and generally went everywhere on it. I loved that bike, even though it was, maybe, slightly too small for me (so that is not a new thing for me). After a year or so of racing a Marin Mt Vision Pro full suss XC bike came up for sale at the LBS, at a much reduced price (it was September so they were clearing out ready for the new model year). It was a lovely bike, fast, all the toys and light. Over the next 10 years I think I rode it about 20 times, tops. I tried racing on it, but couldn't get on with it, I kept it thinking I would come to love it, but each time I went to the garage to get a bike out, the Pine Mountain would be the one I chose, not the Mt Vision Pro. Eventually I sold them both(as I switched from off road to on road), but the Pine Mountain is the one I miss.
