Technology:

Inter-8
Shimano 8-speed gear hubs with Inter-8 technology have a total gear ratio of over 300 percent. Due to the close gradation of the gears, they enable a smooth, efficient cadence and thus greater comfort while riding.

Gear Change Support
Gear Change Support is a shift servo technology on Shimano gear hubs. It ensures that you can downshift quickly, precisely and without using a lot of force, as it uses part of the pedal force for this process. The pedal force acts against the shift cylinder to overcome its counterpressure and execute the gear change. The shifting force is thus reduced by 40%.
