Shimano - 105 group set
The racing heritage of 105 is reflected in designs that have evolved directly from Shimano's experience in pro road racing. The 105 components are interchangeable with Dura-Ace and Ultegra due to identical 9-speed drive train specifications. For the year 2003, the whole line of Shimano 105 has done its minor change. The two color versions of black and silver are available now. By upgrading metal finishing, the group actualized its facelift of great value.
