This is a vintage1995 Trek 8700 3 tube carbon hardtail mountain bike.  This bike was definitely pushing the envelope as far as technology goes and its light with a great ride.  The 3 carbon tubes really isolate bumps and vibration generated from rough off road trails.  This bike is slightly not original - it was mainly an LX/XT bike, but now has several changes.  The rear wheel has been swapped out to a Deore/Sun combo with a new 7 speed cassette.  New saddle complements the original seatpost, but the stem has been swapped out for a Titec item.  Still has the original LX rapidfire shifters/brake levers, LX front derailleur, XT rear derailleur, but the LX crank has new Blackspire chainrings.  The rear tire has been replace with the original front tire while the front tire is a Smoke Dart.
The Shimano 747 clipless pedals are still one of the best pedals on the market, even if they clog up with mud from time to time.  These have been added on and were not stock - they are also fairly worn and beat up.
The Judy XC front fork works well.

Measurements:

Seat Tube (center to center) - 18"

Top Tube (center to center) - 22.5"

Stand-over Height - 31ish"

The bike has several scratches, particularly on the top tube where you can see marks of dismounting.  Front fork is also scratched.
