I bought a Trek 850 also way back and passed it on to my son many years ago when I bought a Trek 930. They are great bikes.I got my first mountain bike in ‘82… got the second in ‘83: Trek 850. That was Trek’s first “rough terrain” bike. Much of it was worn out and replaced but it’s still got the original frame, wheels, crank arms, brakes and saddle. I still ride it… I don’t use the circa 2002 Specialized Epic much anymore — don’t ride as aggressively these days. I did a 3,142 mile tour on the 850 also… Of my 7 bikes the 850 is my favorite.
