A little background: I live on a rail-to-trail, my son learned to ride last week, I am excited to go riding again. My bike is old and uncomfortable on a long ride and weighs a ton. This is my current steed:
Yes, the mighty Quest Crestwood, purchased from WalMart in 1998 or so. Its about as bargain-basement as you can get, but it also gets the job done. The first issue I have with it is that it is heavy, a big deal because I carry it up some steps to get home from the trail and hang it from the rafters of the barn. The other issue is that I lean forward on it a bit too much and my wrists start to hurt after a while. (18" frame, 26" wheels, I am 5'10 with a 30" inseam).
So I am looking to upgrade, but a $1500 bike is not in the cards because I rarely ride and when I do, its paved roads and trails, or the packed gravel of a rail-to-trail. Even $500 is too much, that's motorcycle money. So what should I be looking for? My bike has Shimano shifters, just like the expensive ones. It has brakes just like most of the expensive ones. It has a front fork and seat post spring thing. It has 21 speeds. It has pedals. I am not seeing anything that sets a used bike selling for $250 - $350 worth more than my $25 bike.
How do I know I can sit more upright? Larger wheels? a larger frame? I want the seat to be lower than the handlebars. (I have already swapped the stock bars shown above with some high-rise bars). How can I save some weight? WIll "better" Shimano components really do anything, do they do more than shift gears, because mine do that.
Any names, brands or models I should be looking for? Help an old guy out so I can ride more and get some cardio. Seriously, I need cardio.
