Are you looking to convert your 120 BCD crankset, like the SRAM XX, to a 1x drivetrain for improved performance and efficiency? Look no further! Our 120 BCD chainrings are specifically designed for this purpose and are an excellent choice for riders seeking a seamless and effective conversion. With our patented Drop-Stop® chainrings, you can easily transform your 2x10 drivetrain into a 1x setup, enhancing your riding experience.
  • Fits a wide range of 120 BCD cranksets and 4-bolt spiders, offering compatibility and versatility.

  • Utilizes Drop-Stop technology for extended chainring life and reduced friction, thanks to its innovative wide/narrow tooth pattern.

  • Prevents chain derailment with an alternating wide/narrow tooth pattern that allows for clearance for mud and debris.

Product Specifications and Compatibility

Our 120 BCD chainrings are made from durable 7075-T6 aluminum and are designed in the USA. They are compatible with any 120 BCD crankset or 4-bolt spider, ensuring a secure fit for your specific bike. To maximize performance, we recommend using M10x.75 bolts with a shoulder, as they provide the best retention and are not standard bolts. For a complete conversion, ensure your 120 BCD crankset has a removable spider to accommodate our direct mount rings.
