Praxis Works, using a superior manufacturing process, forges their chainrings from 7075 series aluminum for maximum strength and wear life. This forging, combined with Praxis' LevaTime shifting technology, creates the best possible shift performance. LevaTime combines ramps, scallops, stainless steel shift pins, and tooth profiling in carefully engineered patterns to ensure quick shifts, even under load. These design features, combined with stout construction, make Praxis chainrings an excellent aftermarket choice for Shimano's Di2 systems. Additionally, these rings have been designed for 11-speed compatibility which allows for the use of an aftermarket 110 or 130 BCD crankset with modern drivetrains from Shimano, Sram, and Campagnolo.
Praxis chainrings are sold in matched sets for either compact 110 BCD or standard 130 BCD cranksets. There are two design options - Classic or Clover. The Clover option is available with either a standard anodized matte finish, or a "two tone" finish with polished elements to improve the aesthetic when used with a high gloss crankset.
