It seems a full suspension bike of good caliber is out of my budget and I remember a colleague classmate in ~2002 with a Trek carbon fiber hard tail (front suspension fork) that had a little "give" or flex when in the rear of the bike when the rear was compressed. He said it helped take the "hit" off of bumps while riding. Apparently it was something to do with the material design in that rear part of the bike frame. The best part was he only paid ~$900 brand new from a bike shop around that time period. Does anyone know the model bicycle I'm referring to? I'm interested in buying one since I can afford it now.
