Collectible bike from around 1996 or 1997 designed by mountain bike pioneer Horst Leitner and made by his company Amp Research. I am the original owner. Purchased at Supergo in Fountain Valley, CA. $2,300 new if memory serves me. All systems work perfectly with no issues. A few superficial scratches here and there on its incredibly lightweight aluminum frame but exceptional condition overall considering its age. Considering my age I have changed the handlebar to one with a little bit of rise so you may want to go back to a no-rise bar as spec-ed when new. Also, I've changed the pedals, grips, saddle and tires for the better IMO. Everything else is original. I've aged from real trails to rail trails, so I'm reluctantly selling. This bike has a 19" frame, which I think makes it large or medium large. Please reply with questions or to take a look and ride.
