              HOLLOWTECH II - Perfect balance between stiffness, stability, weight and rotational efficiency
              The HOLLOWTECH II technology concept was designed to produce an optimized crankset that minimizes the rider's effort required for the drivetrain. The high rigidity of the crankset ensures efficient power transmission when pedaling, while its low weight takes the strain off the rider, especially on longer rides. The crankset was developed with a view to achieving an optimum balance between stiffness and low weight. HOLLOWTECH technology enables extremely light, hollow crankarms that are manufactured using SHIMANO's exclusive forging technology to achieve maximum stiffness. In addition, the HOLLOWTECH II crankset has the right crank firmly connected to the axle of the bottom bracket, which achieves an optimum balance between maximum stiffness and minimum weight. The externally mounted bottom bracket offers better weight distribution and more stability, which ensures more efficient power transmission.

              MICRO SPLINE
              MICRO SPLINE MICRO SPLINE reduces weight with a lightweight FREEHUB cassette hub, with the largest chainring having 10 teeth. Use in combination with MICRO SPLINE cassette sprocket and FREEHUB.

              Advantages and features
              • Lightweight aluminum MICRO SPLINE FREEHUB integrates seamlessly with small upper 10-tooth sprockets.
              • Smaller and wider teeth prevent pinion damage on the lightweight aluminum FREEHUB.
              HYPERGLIDE+
              The redesigned cassette and chain of the HYPERGLIDE+ drivetrain represent the new generation of MTB touring - with improved speed, shifting efficiency and smoothness on any terrain.

              Advantages and features
              • Better chain retention, greater holding power and smoother pedaling provide more power and a safer riding experience in rapidly changing terrain conditions.
              • The clearly defined upshifting and downshifting in both directions promotes rider concentration and supports acceleration.
              • The highly efficient drive with smoother power transmission ensures greater comfort and less stress.
              • The wide range of gears and cassettes and the combination with one or two chainrings offers support for many different MTB riding styles, experience levels and preferences.
              HYPERGLIDE+ is the launch pad for the new generation MTB experience, as it enables smooth pedaling on virtually any terrain for the first time, while the completely redesigned drive system with its specially developed chain enables faster shifting, efficient power transmission and unprecedented chain stability. It precisely determines the optimum moment for the gear change and thus ensures smooth operation. This makes it easier for riders to adapt to abruptly changing terrain conditions. HYPERGLIDE+ helps riders to master rough trails with confidence. It dampens the pedal stroke and reduces shifting times by a third (compared to the current HG system).

                          HOLLOWTECH II - Perfect balance between stiffness, stability, weight and rotational efficiency
                          The HOLLOWTECH II technology concept was designed to produce an optimized crankset that minimizes the rider's effort required for the drivetrain. The high rigidity of the crankset ensures efficient power transmission when pedaling, while its low weight takes the strain off the rider, especially on longer rides. The crankset was developed with a view to achieving an optimum balance between stiffness and low weight. HOLLOWTECH technology enables extremely light, hollow crankarms that are manufactured using SHIMANO's exclusive forging technology to achieve maximum stiffness. In addition, the HOLLOWTECH II crankset has the right crank firmly connected to the axle of the bottom bracket, which achieves an optimum balance between maximum stiffness and minimum weight. The externally mounted bottom bracket offers better weight distribution and more stability, which ensures more efficient power transmission.

                          MICRO SPLINE
                          MICRO SPLINE MICRO SPLINE reduces weight with a lightweight FREEHUB cassette hub, with the largest chainring having 10 teeth. Use in combination with MICRO SPLINE cassette sprocket and FREEHUB.

                          Advantages and features
                          • Lightweight aluminum MICRO SPLINE FREEHUB integrates seamlessly with small upper 10-tooth sprockets.
                          • Smaller and wider teeth prevent pinion damage on the lightweight aluminum FREEHUB.
                          HYPERGLIDE+
                          The redesigned cassette and chain of the HYPERGLIDE+ drivetrain represent the new generation of MTB touring - with improved speed, shifting efficiency and smoothness on any terrain.

                          Advantages and features
                          • Better chain retention, greater holding power and smoother pedaling provide more power and a safer riding experience in rapidly changing terrain conditions.
                          • The clearly defined upshifting and downshifting in both directions promotes rider concentration and supports acceleration.
                          • The highly efficient drive with smoother power transmission ensures greater comfort and less stress.
                          • The wide range of gears and cassettes and the combination with one or two chainrings offers support for many different MTB riding styles, experience levels and preferences.
                          HYPERGLIDE+ is the launch pad for the new generation MTB experience, as it enables smooth pedaling on virtually any terrain for the first time, while the completely redesigned drive system with its specially developed chain enables faster shifting, efficient power transmission and unprecedented chain stability. It precisely determines the optimum moment for the gear change and thus ensures smooth operation. This makes it easier for riders to adapt to abruptly changing terrain conditions. HYPERGLIDE+ helps riders to master rough trails with confidence. It dampens the pedal stroke and reduces shifting times by a third (compared to the current HG system).
