Product details

Made from 7075 aluminum, the RENNEN chainring is unique thanks to its decimal tooth design, achieved through a slight modification of the chainring's circumference. This allows you to adjust your gear ratio in fractions of teeth as needed, depending on the BMX track you will be riding. It is designed to be mounted on a 4-bolt crankset. Additionally, this version integrates the fastening nuts directly machined into the chainring, eliminating the need for a wrench to tighten the chainring to your crankset.

  • CNC-machined chainring made from 7075-T6 aluminum
  • 4-point attachment with BCD diameter of 104 mm
  • Decimal tooth design
  • Thickness: NC
  • Chain size: 3/32’’
