商品描述

The difference in the effort and time takenfor front shifts between Dura-Ace mechanical and Di2 is truly staggering: withprogrammed automatic motion at the touch of a switch the Dura-Ace Di2 frontderailleur isquick, smooth and effortless, making for unmatched drivetrainefficiency

Features:

High tolerance cold forged aluminium andcomposite construction

Braze-on fit as standard; if your bike doesnot have a braze-on mount seat tube adapters are available

10-speed Dura-Ace Di2 compatible

Front derailleur weight is 124 grams
