Can anyone identify this Gary Fisher or give me an approximate year? The serial number is FS90071877. I dont know anything about it other than it is a ChroMo frame and has Shimano 400 components. I am a truck driver and wanted a more compact frame to carry in the truck but I also wanted a SS. I know absolutely nothing about MBs but I got this in hopes of dooing an inexpensive conversion to SS. I would really love to have a disc brake also, front or rear or both, dont really care. Any suggestions on the least expensive and still effective way to get this bike to SS/Disc Brake? Tod
