Univega GranTech 6400

The Univega GranTech 6400 was near top of the line in the Univega line up when it came out. This particular bike is equipped with
A full Shimano 600 group (hubs, crank set, brake set, derailleurs, shifters, head set)
700c Mavic reflex sup rims
Phil Wood bottom bracket
Turbo Special saddle
CT Japan handle bars
The frame is constructed of Chromoly rear seat and chain stays with the top and down tube made of aluminum tubes bonded. The late 80's and early 90's saw a lot of experimentation with utilizing different materials to build frames. Trek came out with their 2300 carbon tubes bonded to aluminum lugs and Vitus was building full aluminum bonded bicycles. Often a problem with the Trek and Vitus bikes was a significant amount of flex in the frame as the bike became older or was heavily used. Some owners experienced the stays un-bonding. Univega and raleigh (Technium) on the other hand decided to keep the strength and comfort of chromoly where most of the forces are experienced on the bicycle frame and simply made the top and down tubes aluminum to reduce weight. Only Univega decided to go with the naked look. The bike was equipped with 14 speeds with indexed shifters. Some of the best down tube shifters before the switch to integrated brake / shifter lever combinations. There was little difference between Shimano 600 (first generation Ultegra) and Dura-ace in performance except in perhaps a few grams. Bicycles such as this were the choice of many amateur racers in the late 80's to early 90's.
