This is not especially well organized, but I've put it online to help answer questions about the costs of specific parts (for those folks who either don't want a complete kit, or just want to mix and match on their own). If you don't see what you're looking for, drop me a line and I can let you know what the deal is. PARTS DEALS ARE ONLY GOOD WITH FRAME PURCHASE (sorry for the all caps, I keep getting bugged about parts from folks who aren't frame customers). Prices subject to change at any time, contact me to confirm.
