KOF from Japan Wow I just received by Fed Ex my used Giro Keirin NJS certified frame. Wow It even has used a Hatta BB, Swan HS and a Sugino Mighty SP all NJS certified. Wow built quality and lug work is fantastic. Why for a frame that is going to raced by Pros and perhaps crashed this level of workmanship to me makes no sense. But frame is superb. If interested in photos. Ask My plasn is too build it up with White Industries 2 cog freewheel.To allow at less some choice of gearing, Frok can be drilled for brakes. Charles Nighbor Walnut Creek, CA
