I have a 12 year old Trek 800 Antelope Mountain Bike. It has a steel frame and is a great bike. It's got all its original equipment, except for the rear cantilever brakes (the original pair broke).
I really like my Trek 800. It's great bike and a lot of fun to ride. I mostly ride it on paved and gravel roads. Sometimes I take it on some dirt paths to do somepseudo mountain biking. I just recently tuned it up (with some help from this forum) and it works great. However, the bike is a little heavy and I was wondering if it would be possible (and worthwhile) to upgrade some components in an effort to save weight.
Are there some things that I can do to the bike to shed a few pounds from its total weight? Are there any components (wheels, cranks, derailleurs, head set, chainrings and gears) that can be switched out to save a few pounds or would it not be worth the effort? I'm pretty happy with the bike the way it is, but it might be fun to make it a little lighter for those longer, hilly rides.
