RENNEN 4 BOLTS NT SPROCKET BLACK DECIMAL alu 7075

RENNEN SPROCKET

Rennen sprockets are precision machined from aircraft quality 7075-T6 alloy. These sprockets offering the highest performance and a wide selection of gearing thanks to the decimal gearing. To change your gear ratio by tooth fraction is now available !

  DECIMAL GEARING

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.
