For my 2008 Trek Portland:
Shimano 105 5700 Crankset, Front and Rear derailleurs, Cassette, and Chain; Ultegra 6700 bottom bracket; and Bontrager Race Lite stem (to replace the Specialized one the previous damned owner put on this bike). Gonna have these installed this weekend and the bike overhauled (cabling, bearings, grease, yada, yada). She'll be just like new on Monday!!
