- The larger the number of teeth of the disc, the larger the diameter, thefaster the relative riding, and it will also be more laborious
When choosing a disc with a large number of teeth, be sure to make surethat its diameter does not rub against the frame, otherwise you need toreplace the longer bottom bracket
Compatible chain speed is 9/10/11 speed,the chain must be lengthenedwhen changing the number of plates
Be sure to confirm that the BCD is 130mm before buying!
