The decimal gearing is achieved by slightly modifying the sprocket circumference. For example: you drive in 43x16, too difficult to ride, and you know that the 42x16 is too easy. You can now adapt your gear using the 42.2T or 42.7T sprockets.
The number of teeth is the same but the decimal gear will allow you to have better feelings with respect to the gear ratio compared to your physical capacities when pedaling.
