Tough and hard!
Precise cold forged and anodized 7075 T6 aluminium time trial chainring-set for 130 mm, 5-arm cranks. It got a very complex shaping of every teeth to better control the chain during upshifts and downshifts. Inner and outer ring are matched together to be in perfect sync at the moment you shift.
Cold Forging - All of praxis works chainrings are created with their proprietary forging process which allows them to manipulate the ring shape and tooth profile more than ever before. With "One-Shot" forging the company is 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 with over 1000 tons. 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.
Leva Time - 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. All of the Praxis ring combinations are "Matched Sets" precisely designed in concert for an optimized shifting experience.
