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 largely interchangeable with 10spd Dura-Ace and Ultegra due to the drive train specifications. Each Shimano 105 road racing group integrates a wide range of advanced functions that not only improve the cyclist’s performance, but also make the bike a lot more fun to ride. With an upgraded surface finish 105 offers a bold looking, durable high performance groupset capable of expert level road racing.
