thanks for the info guys, ill check out the book on ebay as well as the supplys. my idea is to build three wheel sets for the same bike. it will be a retro track bike but fixed isnt always a right application for where I live, we have lots of hills here so a three speed will help, maybe a coaster brake with a heavy rim and spokes for dirtroad riding that way I can get some great skid action going when I feel crazy and recless. so im thinking change your wheels and it will change your bike.
