Light to the touch but positive & crisp, Vivid indexing provides a constant amount of shift lever force across all 10 sprockets. 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. Dyna-Sys 10-speed compatible
- for use with precision 10-speed MTB drivetrains. Pod design allows the use of these shifters with any brake lever. 2nd generation I-spec-B design is developed to attach directly to I-spec-B brake levers. Please Note: I-Spec B is not directly compatible with I-Spec A or I-Spec II brake levers.
