Technology:

Cold Forging Process
The primary reason why Praxis Works chainrings are cold forged is because it allows you to produce unique tooth shapes and shifting ramps. In addition, the one-shot process makes the surface harder and more resistant, which is not possible with CNC chainrings. In practice, the process delivers high shifting precision and long service life.

LevaTime™ II
The LevaTime II X-Ring chainrings are an ambitious further development of the first LevaTime chainrings. The large chainring is now stiffer and 5 mm thick, allowing Praxis Works engineers to increase the number of shifting ramps forged into it and improve the type of shifting features. This also made it possible to fit new forged, fast-acting shifting pins, which increase the speed of shifting. Holding it all together is the reworked forged LT2 X-Spider, for added stability.
