I just realized, my newest bike, a Giant Cypress DX, that I bought new, off the LBS showroom floor ... is 14 years old. So, it must be obsolete. Even with under 2,000 miles on it, it needs a complete rebuild and upgraded, to be "useable". I was going to do a couple upgrades/modifications to make it suitable for on/off road touring, anyway, but now that everything but the tire size is obsolete ... is it worth it?
