Chroming is a very expensive business in any event- even the disposal of the toxic wastes, etc. is also very high. Not every chromer can chrome bikes-they require large tanks (for a full frame), the tools to work around the BB, and the knowledge of getting rid of the acid that enters the frame during the process. Any chromer that works with Brian and Joe must be very good indeed. I suspect that full frame chroming for a private customer will be between $1000-2000 depending on various factors. Note that if cable guides are braised-on polishing/chroming that area will be very tough-cheap chrome jobs will often leave the BB area painted black. Also, if you're going to put decals on the framest will need clearcoating-another expense. The finest chroming I've ever seen was on ICS framesets-their gilding was also without par.
