The Nexus 7-speed was the first common hub with rotary shifting. Though often praised for its smoothness of shifting, its protected cable connection and its even progression of ratios, the Nexus 7-speed has been criticized for low efficiency in the middle gears, and for short wear life due to the small sun-gear pawls. Newer models of this hub may have improved reliability. | The Nexus 7-speed was the first common hub with rotary shifting.
