大略看了一下, 瞄到了重點!!
How you can see in the list abovee, the Master and Expert cathegories have dissapeared as 26 inches classes and have been absorbed by the 20 inches classes. If this change is finally approved, the rear derailleur of the 26 inches will be eliminated and 26 inches riders will feel free to use “singlespeed” bikes without any objection.
終於可以用單速了!!! ~QQ~
