Deore M5100 mountain bike Rapidfire shifter pod featuring 2-way release for cost effective 11-speed shifting performance. Light to the touch but positive and crisp, Vivid indexing provides a constant amount of shift lever force across all 11 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. 11-speed compatible - for use with precision 11-speed MTB drivetrains. Pod design allows the use of these shifters with any brake lever. Multi-position adjustable handlebar clamp for custom lever positioning. Barrel adjuster for fine gear tuning. Complete with Optislick inner and SP41 outer cables. Easy access clamp band adjustment for quick set up. I-spec-EV design is developed to attach directly to I-spec-EV brake levers.
