The Shimano R783 2 / 3 x 10 Speed Rapidfire Shift Levers are precise mountain bike style levers for road bikes fitted with flat handlebars & 10-speed drivetrains. The instant Release allows for super fast shifts, delivering the chain to the next gear the moment the lever is actuated with no hesitation & the Multi-Release allows multiple gear changes from both levers with one sweep, further adding to the speed of shift. 2-Way release allows the upper shift lever to performs the same Multi Shift function but swings in either direction allowing it to be released by the thumb or index finger. The Low-friction design means that shifters have a light & responsive short-stroke action that reduces shifting effort. Sold as pair in a high tech polished & grey finish, complete with inner & SP41 outer cables.
