Technology

Mega 9 Lite

• Light pedaling with efficient drivetrain
• Optimal gear ratio for each wheel size
• The larger the wheel the more range needed in the cassette to maintain light pedaling
• Refined front shifting system
• Gear combinations specialized for each tire size reduces the number of recovery rear shifts needed with front
  close gear ratio
• Tire clearance improved for better maneuverability

Optical Gear Display

The Optical Gear Display tells you which gear position is selected while riding your bike. You can see how many
gears you can select either on the low side or top side, which makes shifting control easier.

Reach Adjust

Brake lever is equipped with a reach adjust mechanism. The distance from handlebar grip to lever can be adjusted to
suit any hand size, type of riding and individual rider preferences.

Rapidfire Plus

Mountain bikers have used Rapidfire Plus since 1985. Rapidfire Plus is still a winning choice from a wide range of
riders from XC racers to freeriders. Rapidfire Plus is suited to quick shifting, giving riders the ability to
downshift three gears in one stroke. Rapidfire Plus shifters from Deore to XTR all feature 2Way-Release, which means
release shifts by pull of the index finger or push of the thumb.

2Way-Release

The Rapidfire Plus shifter release lever is commonly called a trigger because it is operated like a pistol, by
pulling toward the grip. The release lever of Rapidfire Plus shifters from Shimano Alivo to XTR can be operated in
this same manner but adds the ability to activate a release shift by pushing with the thumb.
