1992 Rock Lobster Gimpsman:

Nicely made fillet-brazed frame with matching stem and fork.  Components are pretty much all XTR with the exception of the Dura Ace front track hub and ST brakes.  The brakes have engraved numbers on them so they may be early prototypes.  Below is some of the info from Paul Sadoff about this bike.

 "I know the frame you are speaking of well. It's a team issue fillet (un-filed) made originally for Kim Seargent ( now married to Joe Murray).  The bike has a lot of hard miles and Kim was a decent racer as well as one of the "Mutants" , a renegade group of MTB riders in the early '90's in Flagstaff. Kim was working for A-5, a company that made really durable packs of all kinds but the one pack that all the Mutants had was the "Gimpsman" pack....;..an indestructible Cordura fanny pack that was big enough for a 12-pack of beer but remarkably compact. Kim left A-5 and formed her own company " Evil Kim packs" which she sold after a number of years. I got a gimpsman pack made by Kim at A-5 in 1993. I still have it and it has no holes in it. I have taken that pack to many places here and in Europe.....it refuses to die. That frame I built for Kim was made like the pack.....it won't die easily. I think Kim had that bike for 14 years."
