http://motorbicycling.com/images/smilies/cptr.gif Recently put a 48cc zbox kit into a steel Fluid mountain/road bike hybrid. Lots of fun around the bayside bike paths etc. After 1000km did a couple of spokes. Had the wheel rebuilt with 14 gauge swiss spokes, back on, running fine. Anyone know where the big blue book of bicycle repair is available for free download? Also interested in a spoke tension meter eg. TM-1. Any suggestions?
