Affordable, performance STI shifting for 7 speed drivetrains, the new Shimano Tourney Levers bring an extra level of comfort & control to older drivetrains by combining their classic STI design with an anatomically shaped, soft rubber hood for easy braking & shifting control regardless of your hand position. Adjustable reach on the main lever & light action releases ensure that shifting & braking is easy while custom fitted to your hand size. Shimanos index shifting system ensures accurate, smooth shifting throughout the range. Large, clear optical gear display makes it easy to see which gear youre currently in so you know when its time to drop the large ring to maintain optimum chain line to help improve drivetrain wear & reduce noise.
