Made from machined 7075 Aluminium, the RENNEN sprocket is unique thanks to its decimal tooth configuration, achieved by a slight modification of the sprocket circumference. This allows you to adjust your gear ratio by fractions of teeth based on your needs for the BMX track you'll be riding on. It is designed to fit a 4-bolt crankset. FEATURES: • CNC machined 7075-T6 Aluminium sprocket • 4-bolt BCD mounting with a diameter of 104mm • Decimal tooth configuration • Thickness: NC • Chain pitch: 3/32'' • Weight: 102g (44.2 teeth) RENNEN has specially developed a tooth profile that allows you to modify the size of an existing tooth configuration. This lets you make it a bit harder or a bit easier depending on your needs. Changing your gear ratio by a fraction of a tooth is now possible. The decimal gearing is achieved through a slight modification of the circumference so that it affects the deployment and/or feel of a gear ratio setup without changing the number of teeth on the gear. RATIO GUIDE RENNEN DECIMAL For example, if you are riding with a 44 x 16 and want to lower your gear slightly, but the 43 x 16 is too easy. With the decimal gearing, you can have intermediate teeth sizes, such as 43.7 or 43.2. Benefits: a wider selection of gear ratios, gear adjustments without changing the rear sprocket, without changing your chain length, and without changing your rear axle length, plus saving time on last-minute gear changes before the race.
