Technology:

Rapidfire Plus
Rapidfire Plus is a type of Shimano shift lever construction that has been common in the mountain bike sector since 1985. Two levers, the main lever and the release lever, are used instead of a twist shifter. Rapidfire Plus shift levers, as the name suggests, ensure fast shifting. In addition, depending on the model, it is possible to downshift up to three gears with one shift stroke.

2-Way-Release
With 2-Way-Release, the shifter can be pressed and pulled to shift to the smaller sprocket or chainring. This allows you to adjust the shifting process to your personal preferences. Most Rapidfire Plus shifters are equipped with 2-Way Release.
