- One-Shot Cold Forging: Exclusive manufacturing process creates a more complex tooth profile and allows more shifting features on a chainring which normal CNC manufacturing won't allow. Individual tooth profiles, alternating tooth angles, timed ramps and tactically placed shift pins are all jam packed onto a Praxis ring. Process creates a harder and tougher tooth overall durability
- LevaTime: Praxis unique timing and shifting technology. Several shift pins are placed strategically at points on the ring to provide a perfectly timed lift. Synchronized ramps are tuned with a specific inner ring, providing a clean channel for the chain to move
