Tough, aggressive and lightweight Dyna-Sys11 11-speed SLX Rapidfire shift levers with vivid indexing and 2-way release function. They are light to the touch but provide a positive and crisp shifting experience, with vivid indexing offering a consistent amount of shift lever force across all 11 sprockets. The 2-way release allows shifting from various riding positions; the upper lever still performs the same shift function, but it can now swing in either direction, allowing it to be released by the thumb or index finger. These shifters are designed for use with Dyna-Sys11 11-speed only. The pod design allows the use of these shifters with any brake I-spec-II lever, and the removable optical gear display with integrated cover allows for compatibility with any brake lever. A barrel adjuster is also included for fine gear tuning. The shifters come complete with inner and outer cables, and feature a multi-position adjustable mount for custom lever positioning. The I-spec-II design allows for direct attachment to I-spec-II brake levers.
