Praxis Aero / TT 5-bolt Chainring Set

Praxis still 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.

INSTALLATION

Praxis chainring sets mount as easily as any other chainring. The only small difference is the short or long catch pin and placement. Simply put align one of the two pin holes with the crank. Then select the long pin if it will fit, or if not use the short pin. After installing the pin you can then grease and mount your chainring bolts. As with, all threads and metal on metal interfaces we highly recommend using a high quality grease.
