You would be doing a wonderful service if only it would educate the average buyer how to correctly describe a rather basic part of a bike. I mean really basic features like: Head tube, headset, fork, steering tube, fork crown, stem... It is painful to read eBay or CL ads describing: "that thing what turns the bike at the front end got some rust..."

Illustrations are great for people looking for quick data, and yours would be perfect! - Very Nice!

For simple bicycle repair or maintenance, was there ever a "Complete Idiot's Guide to..." or a "... For Dummy's" - like there were the series of books for VW Beetles, etc. during the 1970s. If not, one is definitely overdue!
