The Shimano Shift/Brake Lever Left 3s is a reliable and intuitive control unit designed for bikes with a triple front chainring. Combining both shifting and braking functions in one ergonomic lever, it keeps your cockpit clean and easy to use, especially on city, trekking, or hybrid bikes. The left lever operates the front derailleur across three chainrings, giving you a wide range of gearing options for climbs, flats, and descents, while also providing smooth, predictable braking control at your fingertips.
Built with Shimano’s proven durability, this shift/brake lever is engineered for consistent performance in everyday riding conditions. The lever shape is designed to be comfortable for a wide range of hand sizes, helping reduce fatigue on longer rides and making gear changes feel natural and precise. It is an excellent choice for replacing a worn or damaged lever, upgrading an older bike, or completing a new build that uses a 3-speed front drivetrain. With straightforward cable routing and compatibility with common Shimano components, installation and adjustment are simple for home mechanics and professional workshops alike.
