Well, I start as a courier on Monday!! Im working in honolulu and the weather is almost allways great. Im riding an old nishiki mtb with some 1.5 slicks and a singlespeed conversion with my derailuer(however you spell it) as my chain tensioner. I also have made a few other improvements on the bike. I know all about riding in traffic and all that stuff but, im interested in making a fixed gear using an eno eccentric hub. Does anyone have anyexperience with this hub? Thanks.
