I've left Cuthbertson handy in my bathroom for the past 6 months. In that time, during spare moments, I've learned how almost everything on my bicycle works. It helped me immensely to break down the component groups into easily understood functions such as "drivetrain" -- and after all, why should understanding how a bicycle goes together be any more difficult than understanding how an internal combustion automobile goes together? When things get too ginchey, that seems to be the spot at which one of Morall's pen-and-ink sketches shows up. (My favorite is illustration 11-10, depicting the parts of a down-tube control lever, painstakingly sketched, and labeled as per the text as "thingamabob," "doodad," and "mounting bolt." ... Of course, the point was how fiendishly complicated such an arrangement can be.) The information is clearly presented, and differentiated among mountain, road, and "cruiser" bikes. I'll be moving the book down to my shop this week! :->
