This is a set of Shimano XT dual control levers, model ST-M739. These levers are for 3  x 8 speed drivetrains and cable actuated brakes. These controls came off a bike that I seldom rode. I’d be surprised if there are more than 1000 miles on them. Both are in nice condition. They shift smoothly and with good authority; the action is smooth and the clicks are well defined. There is no gummyness. The indicator windows are intact and clear. The indicator needles still have their distinctive red color. The brake levers close and open smoothly with no hesitation or excess play. The action on these levers feels great. The flaws take the form of a bit of dirt and a the odd lights scratch, nothing significant. These levers are good candidates for your nice vintage bike. I have uploaded large photos. Please take a look. Thanks!
