Hello and thanks for checking out this listing of a First Generation Di2 Shimano Dura-Ace ST-7970 electronic 10-speed LEFT & RIGHT drop bar STI brake/shift lever set! I discovered these parts in the back stock of a high-end bicycle shop as it ceased operating, they will come to you in the new-without-box condition seen in the included pics.

PLEASE NOTE: This *FIRST GENERATION* Di2 shifter set is *ONLY* compatible with Dura-Ace 7970 components and mechancial (cable pull) brakes. It is INCOMPATIBLE with any E-Tube or later Di2 systems. For use with 10-speed drivetrains.

These parts were likely pulled off a brand new bike at the time of sale when another option was chosen they look truly mint with no signs of any use.

Please see the included pics of the actual levers you will receive.
