This is a 1995 Trek Y22 mountain bike. This is a classic carbon Y-frame with a great mix of parts.  Its a mashup of XT and Sram, with some other choice parts thrown in. 

The Y22 originally came with cantilever brakes, but his bike has V-brakes.  The rear swingarm was swapped out with a newer version to accommodate the different cable routing.  The original was polished.  The new swingarm has a replaceable derailleur hanger.  Also, a Rock shox Judy TT was added on.  Both have disc mounts (rear swingarm has the chainstay mounted hayes type) for future upgrades. 
The Fox Alps 4 rear air shock works well.
The bike has been fully tuned up and is ready to go.  Its not stock, but it rides great and would make a great addition to anyone's stable. 
New Bontrager Jones ACX tires were added on at the time of the tune-up.

This bike is the large size.

Ice red color.

** The frame has some scratches on it, especially on the underside of the main beam.
