Praxis 2X road chainrings are the result of relentless testing and tweaking, matched with the best material and manufacturing processes to create some of the smoothest running, most durable and sweetest shifting chainrings available. All other aftermarket rings are machined. For superior longevity and performance, we cold forge ours from 7075 T6 aluminum and hard anodize it for even more durability. They also feature our famous LevaTime Shifting Technology, which boasts synchronized ramps and strategically placed shift pins for perfectly timed shifts every time. Two options : “BUZZ” for lightest offering “AERO/SOLID” for the Aero/TT look.
COLD FORGED – All of our road chainrings are created with our proprietary forging process which allows us to manipulate the ring shape and tooth profile more than ever before. With our “One-Shot” forging we are able to increase the amount of shifting features on a chainring which normal CNC manufacturing won’t allow. The process also 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. Translation: All of these small aggregate features add up to the most durable and consistent shifting rings ever produced for cyclists.
LEVATIME™ – 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 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 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.
