Спортивная звезда PRAXIS Mountain Ring 104 BCD

Every single Praxis chainring is created using their proprietary forging technique, allowing Praxis to delicately manipulate the ring shape and tooth profile more than ever before. With Praxis One-Shot forging, they are able to increase the amount of shifting features on a chainring above that of which normal CNC manufacturing would allow. The process also creates a harder and tougher 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.
