Up for sale is a 1991 Trek 8900 Pro with all of the goodies from that era. Frame size is 20.5" C-C so a large or xl. Wheels are Bullseye hubs with Matrix Aero rims, hard to find in this condition and originally equipped. Tires are repop Smoke and Dart Panaracers, Stem and bars are Matrix as well, correct for the bike. Fork is a Trek DS2 which was added, bike had a rigid so an upgrade there. Derailleurs are Shimano M735, Suntour XC crankset, brakes, levers and pedals, Grip shifters, Turbo Special saddle, Ritchey post. I did remove the old stickers as they were almost all gone and re-clear coated the carbon tubes then installed repop stickers, like originals. Fork is slow at rebound and is fully functional, I do not know how to fix that but you may. May trade for other pre-1998 vintage MTB's or hard to find parts.
