Praxis Chainring Set Buzz 130 BCD 10/11/12 Speed Black

he Praxis Works Buzz chainring set with LevaTime shifting technology is suitable for mounting on any Praxis 5-arm road bike crank. Praxis Works 2x chainrings with LevaTime are simply a class of their own when it comes to shifting precision and speed.

This technology has been developed over the years, through intensive testing and constant optimization, always. The complex arrangement of climbing aids, gouges, ramps and tooth shapes is from the small to the chainring is precisely calculated and in no way coincidental. Thus, the chain changes position absolutely controlled and efficient. LevaTime raises the switching behavior to a new level - try it out and you will notice how different practice Works chainrings are. 

Many small things bring in the end in the sum of the decisive, big advantage. Thus, the cold forging process contributes a significant part to why Praxis Works chainrings are so exceptionally good. Through the specially developed for chainrings themselves OneShot- pressing and compression process, Praxis Works chainrings have significantly more and significantly more complex climbing aids, shifting aids and tooth profiles than only CNC manufactured blades of many other manufacturers. In addition, the forging process provides a harder and more wear-resistant surface. The chainrings to forge is a technically highly demanding and expensive, additional, manufacturing step. So it is not surprising that most other manufacturers prefer to save this. However, it is precisely here that the decisive advantage of Praxis Works chainrings arises, because the process simply allows a much more advanced shift aid design.
