Well, I got "The Ultimate Bicycle Book" and "Bicycling Science 3" for christmas. I read "The Art of Urban Cycling" by Robert Hurst a couple of months ago, and watched Ned Overend's Performance Mountain Biking video.
The stuff that sticks with me are some of my older books like "Bicycles In War" by Martin Caidin and "Between my Legs" by Chaim Sil.
