Praxis BUZZ Chainrings : STANDARD 53-39 : Black

Season:2016

Brand:Praxis

Code:PR-5339-4004

The new Praxis Works compact BUZZ road chainring sets are engineered for the highest performance shifts in all conditions. LevaTime® performance and a proprietary forging process give the fastest shifts and longest lifetime of any ring on the planet.

A clever redesign of the rings allows fitting on both traditional 5-arm cranks and also newer 4-arm with 5th Hidden-bolt designs such as SRAM Exogram. In addition the rings' shifting ramps have been designed to work with all modern electronic systems including Di2, EPS and SRAM eTap indeed, all Sram shifting systems that utilise YAW front derailleurs.

The rings now also include long and short threaded catch pins and can be used with all Shimano, Sram and Campag 10/11 speed drivetrains. However, they are not compatible with Campagnolo cranks because of their proprietary bolt patterns.

Shifting on Praxis is sublime, slick and definite. All Praxis works road chainrings are created with a proprietary forging process which allows the manipulation of the ring shape and tooth profile more than ever before. Praxis' “One-Shot” forging enables an increase in 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. The result of these small aggregate features adds up to the most durable and consistent shifting rings ever produced for cyclists. Combined with the forging process, Praxis' LevaTime™ shifting, the product of years of relentless testing and tweaking, results in 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.
