I currently have a 12-yr-old (at least) Specialized Hard Rock, but have hardly ridden at all in the last 5 years or so due to being more involved in distance running, which takes up a lot of time. I'm backing off on running now and have the itch to start riding again on a more up-to-date bike.
Most of my riding is on bike paths and improved rail-trails, but I might also be riding some unimproved, rougher rail-trails and occasionally some single-track stuff. But no extreme climbing, downhills, jumps, or anything like that. I'm 57 now and don't enjoy getting bounced around like I used to . On my current bike, I replaced the knobby tires with inverted-tread tires that have a lot less drag on pavement and hard-pack and are suitable for 90% of the riding that I have been doing. Since I still will not be riding all that often, I also want to stay within a reasonable budget (IOW, no full-suspended MTBs).
I've looked mostly at Trek and am trying to decide between a "comfort" bike like the Nav 300, or a mid-range MTB like the 7400. A test ride is in order, but right now I think the Navigator might be better from a comfort standpoint and would be more suited to my type of usage. Any comments?
