NOT YOUR AVERAGE CHAINRING

Our LevaTime™ shifting is the product of years of relentless testing and tweaking. The final result is a set of some of the finest and fastest-shifting rings available. With a LevaTime™ ring, several shift elevators 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 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.

After riding these rings, you’ll realize these aren’t your average, ordinary chainrings.

LevaTime™ takes shifting to the next level.

TIMING IS EVERYTHING : MATCHED SETS

Like all great marriages in life, timing is everything. A large part of our LevaTime™ shifting system is the timing and clocking of the outer and inner rings together. All of the Praxis ring combinations are “Matched Sets” precisely designed in concert for an optimized shifting experience. Praxis engineers spend an obscene amount of time laboring over tooth shape, ramping, and the precise location of shift elevators. All of this is done in order for the inner and outer ring to be in perfect sync at the moment you shift.

NO TWO TEETH ARE ALIKE

One thing many people notice right away is the complex shaping of the teeth on a Praxis chainring. With all the duties required of a chainring for smooth shifting, we needed to sculpt very elaborate teeth profiles to better control the chain during upshifts and downshifts. By forging a chainring where no two teeth are alike, we create a ring-set that allows the chain to smoothly move laterally and vertically.
