The praxis works Buzz Road set consists of 2 precise cold forged chainrings for 130 mm, 5-arm BCD. They offers superior stiffness because of the 7075-T6 aluminium and the stamped and machined manufacturing with hard black anodizing guarantees durability. The chainrings are great for the use with Shimano's Di2 or Campagnolo's EPS system and are furthermore compatible with InfoCrank, Power2Max, SRM and Quarq power meters.
Cold Forging Chainrings
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 one of the most durable and consistent shifting rings ever produced for cyclists.
Leva Time® 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 sculptured to handle a specific duty. Along with that, precisely located scallops help control chain movement and prevent chain suck.
Buzz Road 130 Compatibility:
The chainring set is compatible with Shimano 10-/11-speed (also Di2), SRAM 10-speed and SRAM 22 11-speed as well as Campagnolo 10-/11-speed (also EPS) drivetrains. It can't be used with Campagnolo 5-arm and the new Shimano Ultegra 6800 and Dura Ace 9000 cranks because of their proprietary or rather asymmetrical bolt circle diameter design. The manufacturer recommends the use of a Shimano, KMC or Campagnolo chain.
Note: Cross gearing small/small - If the two smallest chainrings are chosen there can be a contact between the chain and the front chainring or front derailleur.
