Tilting the balls changes their contact diameters and varies the speed ratio. [5] [6] As a result, the NuVinci CVT system offers seamless and continuous transition to any ratio within its range. The gear ratio is ...

    The width of early Shimano 6- and 7-speed cassettes was 36 mm, and early 8-speed 40 mm wide. Shimano then changed again and standardised 8-11 speed cassettes on 41.5 mm and second generation 7-speed to 38 mm. The widening of the sprocket carrier on the cassette hubs to 41.5 mm resulted in a decrease in the distance between the hub flanges.
