E-TUBE Technology
E-TUBE is Shimano's "service" that uses websites or apps to maximize the joy of cycling by connecting riders, bikes, and Shimano.

HG
The dedicated HYPERGLIDE+ chain offers better retention, more efficient shifting, and smoother transmission on rough terrain. This different design reduces the vibrations normally caused by the inner and outer links passing over the chainring and provides better chain engagement, greater retention, and a smoother pedal stroke.
