If you liked Bike for Life and Heft on Wheels (two of my favorites), then try Ten Points by Bicycling editor, Bill Strickland. A great story about cycling and psychology, overcoming one's inner demons through sport. A very good read, especially for the older cyclist.

Another favorite is the new Cycling's Golden Age: Heroes of the Postwar Era, 1946-1967, The Horton Collection by Brett Horton, Shelly Horton, Owen Mulholland, and Eddy Merckx. This features LOTS of photos and great biographical information about cycling's greatest riders. One of the best, for certain.
