Deore mountain bike Rapid-fire shifter pod featuring 2-way release for cost effective Dyna-Sys 10-speed shifting performance. Light to the touch but positive and 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. Pod design allows the use of these shifters with any brake lever. Multi-position adjustable handlebar clamp for custom lever positioning.
