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 10-speed drive train specifications.
Components: Ergo/STi levers with cables, brake callipers, chain, chainset, bottom bracket, front/rear changers, cassette.
Groupsets do not include pedals, headset or hubs; these must be ordered separately.
