Shimano's Tiagra SL-4660 Rapidfire Shifters will have your ride shifting quickly and efficiently. Designed specifically for flat bars with a classic MTB style in mind, the levers have three different actuations that deliver immediate shifting that is smooth and precise. Instant release immediately shifts a single gear, Multi Release allows multiple gear changes using both lever simultaneously, and 2-Way Release on the front shifter can swing forward and backward, allowing for use of both the thumb and index finger to shift. Polished grey, both levers have easy to read shift indicators and include barrel adjusters for fine tuning Note: Works ONLY with 10-speed setups that use Shimano FD-4600, FD-5700, or FD-6700 double front derailleursrnFeaturesIncludes: Two (2) shifting levers w/ shifting cables and barrel adjusters3 actuations: Instant Release, Multi Release, 2-Way ReleaseLow-friction designEasy to read indicatorsBarrel adjusters for fine tuningIntended for use with flat barsSpecsSpeed: 3x10spColor: Polished greyMaterial: AluminumClamp Diameter: 22.2mmShift Lever Actuation: Instant Release, Multi Release, 2-Way ReleaseFront Derailleur Compatibility: Shimano FD-4
