I'm going on a three week trip in a few weeks, and the director (who I am good friends with) has asked me if I could rent my spare bike to another rider. I'm trying to figure out what would be a fair price to charge for the wear and tear from a fairly inexperienced rider over 1500 miles.
My guess is that the following parts will have enough wear to warrant replacement (or at least some compensation): chain, handlebar tape, brake pads, cables, and tires. I also want to figure in some general wear on everything else. The bike is an early-90's Cannondale 2.8 frame built up with mostly 105 components. I take very good care of it since normally it is my primary means of transportation.
I basically have no idea what a fair price would be. I would love some suggestions.
