Newly redesigned, the Shimano Tiagra 4703 triple front derailleur features a revised cable pull and extra wide pivot link for quicker shifts. The Tiagra 4703 front derailleur new cable pull only works with the Tiagra 4703 STI Shifters or the Tiagra 4703 Flat Bar Shifters, it will not work with other Shimano triple shifters. To save weight Shimano switched out the steel pivot links and clamp for aluminum, that also adds rigidity.

asked by: a guest Similar question, will this work with 10-speed bar end shifters?
A.
anwered by: canteau If the bar end shifter is friction there should not be an issue, if the bar end shifter is indexed it will need to use the revised cable pull that Shimano uses.
