The racing heritage of Shimano 105 groupset is reflected in designs that have evolved directly from Shimano's experience in pro road racing.
The 105 5700 group of 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.
