Shimano 105 5700 10 double front derailleur and Shimano 105 5703 10 triple front derailleurs have wide link design for increased rigidity and improved shifting response for use with Shimano 105 ST-5700 or Ultegra ST-6700 shifters for optimum shifting performance but will work with other models.

The wide inner link increased rigidity and takes front shifting performance to a new level, especially under heavy loads on 10-speed drivetrains whilst the light action spring reduces effort required to actuate shifts.

Maximum capacity of 16 teeth with 50-56 tooth outer rings. The aluminium parts are coated to resist corrosion and maintain their great looks
