One of my bike buddies went on a cruise for two weeks, and I said he could drop off his bike and I'd install the new cassette and chain he bought. (at my insistance) The bike is a three year old Trek 7200, which I had worked on before for him. Well, I'm just blown away by how dirty everything is, and by the complete lack of maintenance. Disgusting!
So, I cleaned it all up, installed the cassette & chain, adjusted the ders, lubed the jockey wheels, lubed the headset and brake pivots and installed new brake pads. It looks and runs great, again. I'm going to recommend new tires this winter as well as getting the hubs serviced and the rear wheel trued. With that, it will be as good as new.
So, what's my beef? Why do people let stuff go like this? Maintenance is so easy and inexpensive. Yeah, it takes a little time, but not that much. I just don't get it. OTOH, I do feel that doing it for him tends to encourage this slack behavior. What to do? bk
