The two big stories for 1987 were the introduction of Treks bonded aluminum technology to mountain bikes and the new Shimano Deore XT index shifting system. Trek used an un-weldable 7178 aluminum tube set bonded to a set of cast aluminum lugs. This allowed the frame to be assembled from mid-sized tubing and eliminated the stress of welding the aluminum. The idea was to obtain a more comfortable ride than the oversized frames from companies such as Klein and Cannondale while saving about 3/4 of a pound of weight. Trek offered this frame in the 8000 XT and 8000 models. The 8000 XT used the new Shimano Deore XT component group with 6 speed index shifting, Biopace chain rings and chain stay mounted U brake.
