Praxis Aero / TT 5-bolt Chainring Set

Praxis Aero / TT chainrings ensure fast shifts for Shimano Di2 systems with its stout 7075 aluminum construction and LevaTime technology. The forging process maximizes strength and wear life while the ramps, scallops, stainless steel shift pins, and tooth profiling enable quick shifting even under load. Engineered for 11-speed compatibility, these rings allow the use of an aftermarket 110 or 130 BCD crankset with modern Shimano, SRAM, and Campagnolo drivetrains. Praxis delivers optimal shifting performance to enhance your ride.

Mounting Praxis chainrings is simple. Align the pin hole with your crank arm and insert the long or short pin depending on fit. Grease the threads and install chainring bolts, ensuring metal interfaces are lubricated for smooth turning.
