This is a first generation Trek full suspension bike.  The T3C swing arm (travel equals three times compression) was not a very robust system.  The elastomers were not very well suited for the task and the bikes did not perform very well.  Trek also tried to market their own line of front shocks which were made by Showa in Japan.  The shocks only lasted a couple of years before Trek started specing "brand name" forks
