10-11-12-speed mountain bike shifting

Shifting on the SL-M7000 levers is taken care of by ergonomically designed RAPIDFIRE PLUS shift levers, allowing riders to downshift three gears in one stroke and release shifts by the index finger or the thumb. This simple but incredibly useful feature also provides light and consistently stable shifting across front and rear gears. I-spec II (SL-M7000-I) and I-spec B-type (SL-M7000-B-I) mount options allow for adaptable and versatile, rider-tuned cockpit options. Now 11-speed, new SLX M7000 brings powerful, dynamic performance that establishes a new benchmark for mountain bike excellence. With DYNA-SYS11 Shimano encourages modern mountain bikers to ride anywhere with its advanced gearing concept that helps maintain rider efficiency. Designed with both XC and aggressive trail riders in mind, DYNA-SYS11 brings enduring performance thanks to smart materials and enhanced drivetrain stability due to new derailleur and chainring designs.

The release lever of RAPIDFIRE Plus shifters from ALIVIO to XTR can be operated in this same manner but adds the ability to activate a release shift by pushing with the thumb. 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 2-WAY RELEASE, which means release shifts by pull of the index finger or push of the thumb.
