Collectible bike from around 1995 designed by mountain bike pioneer Horst Leitner and made by his company Amp Research. I am the original owner. $2,300 new in '95. 19" frame size which is medium/large. All systems work perfectly with no issues. A few scratches here and there on its incredibly lightweight aluminum frame but exceptional condition overall considering its 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 it had been speced when new. Also, I've changed the pedals, saddle and tires for the better IMO. Everything else is original. I've aged from real trails to rail trails, so I must reluctantly sell. Please reply with questions or to take a look and ride.
