With "One-Shot" cold forging, Praxis Works is able to increase the amount of shifting features on a chainring, which normal CNC manufacturing won't allow. The process creates a harder and tougher tooth surface for durability. Individual tooth profiles, alternating tooth angles, timed ramps and tactically placed shift elevators are all jam packed onto a Praxis ring. LevaTime technology places several shift pins at points on the ring to provide a perfectly timed lift and synchronized ramps are tuned with a specific inner ring, providing a clean channel for the chain to move upwards. Each individual tooth is sculpted to handle a specific duty. Along with that, precisely located scallops help control chain movement and prevent chain suck. All of these small aggregate features add up to the most durable and consistent shifting rings ever produced for cyclists.
