Is it possible to set up a road racing bike for touring? I bought a Specialized Ruby earlier this year, so I can't really afford another bike. It has no eyelets for attaching racks (so I'm limited to 20-25 lbs on a rack clamped to seat post). Also, the chainstays are only 40.5 cm - would rear panniers get in the way? For now, I'm looking at doing a 3 day solo tour down the Pacific Coast. I'd be trying to travel as light as possible (no cooking stuff, tarp instead of tent, etc). Should I get wider tires (running 700x23)? Would this be too much stress on the wheels (16 spoke in front, 20 spoke in rear)? Sorry about all the questions!!
