Shimano Dura-Ace ST-R9170 Hydraulic Disc Brake Di2 Lever Left. This item is in a used condition. It is in need of some servicing as it has a sticky/slow returning piston. Other than that, all other functions are working fine. The bleed screw is all good/with no issues. Shift buttons/levers work fine. The lever does show some minor scratches down at the tip, almost invisible though. Never been crashed on.
