This is one of the first full suspension mountain bikes made in USA. It is modeled after Gary Fischer (inventor of mountain bikes) prototypes and has had little use. It was riden by Henrik Djernis when he won the 1994 UCI Mountain Bike World Championships in 1994.
Has been parked in the garage for years since I was involved with a lift accident and then fell in a mud hole that was covered with leaves. Due to the injuries I could not ride it.
New tires and cables etc, since I was going to give it to my grandson but it won't fit in his car.

The only non original part is the seat which can be replaced if desired. Local shops tell me that sales of these rare bikes start at $500 can increase to $1500.
