I've been riding an old Gary Fisher Tassajara this past season, mostly on single track thru the woods. The trails are hilly, narrow, muddy, studded with rocks, fallen logs and lots of "corduroy" sections to navigate. The GF has done me pretty well, but I'm thinking of getting a new bike for next season but all the choices are confusing. The GF is a simple, "no suspention at all, thank you", hard-to-beat bike. Most MTBs now seem to come with at least a front suspension, and lots w/ front and rear. And then there's the standard 26" vs the new 29R question. So, given the type of riding I do, would I be happier w/ a 29R or a 26R? Full suspension or just front forks? I'm @ 6'2" and 220lbs. The Gary Fisher has been good, but what do I replace it with?
