Praxis has an incredibly well balanced approach to their chainring and crankarm design. Focusing on balance between five main attributes (stiffness, weight, durability, shift features, and price), Praxis has produced more well-rounded products than many competitors. One of the most important factors in realizing these designs is their proprietary cold-forging process that allows careful manipulation of the ring shape and tooth profile. The latest generation Zayante Carbon crankset is their most evolved example of these design principles and production techniques yet.

While these cranks feature incremental improvements over previous generations, many of the most important advancements can be attributed to the new Levatime II X-Ring chainrings. Praxis' proprietary cold-forging process allows careful manipulation of the ring shape and tooth profile. In addition, this “One-Shot” forging allows an increased overall number of shifting features, surpassing what is possible for CNC manufactured rings. Not only does this process allow for an increased number of shift features (including individual tooth profiles, alternating tooth angles, timed ramps, and shift elevators), but also results in a harder, tougher tooth surface that increases durability. This increased durability is a result of the refined 7075 T6 aluminum grain structure achieved through the forging process. These innovative production techniques allow Praxis to produce some of the most durable and consistent-shifting rings available.

The new Zanyante Carbon crankset is the ideal choice for riders looking for all the benefits of the new Levatime II X-Ring technology at the lightest possible weights (weight savings of almost 100 grams for the 52/26 configuration).  For more budget-oriented riders, the Zayante Carbon-S (available here) features all the performance benefits of the Levatime II X-Rings, albeit at a lower price resulting from the heavier, less-refined rings (however, these rings can be upgraded to the lighter version as the crankarms and X-Spider are identical between the two cranksets).
