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.

- Now including long and short threaded catch pins.
- Cold Forged and Hard Anodized 7075-T6 Aluminum
- Work with Shimano™ 10/11, Campy 10/11, SRAM 10/11 drivetrains
- We highly suggest KMC, Shimano™, or Campy chains
- Not compatible with Campy 5-arm or 4-arm as Campy has proprietary bolt pattern.
- GREAT for use with Di2 or EPS systems
- InfoCrank, Power2Max, SRM, and Quarq power meter compatible
SHIMANO — Buzz rings work great with the new Shimano 10/11sp chain and drivetrains (Di2 included.) These new Buzz rings are made to be mounted on either traditional 5-arm cranks, and now work with 4-arm w/hidden 5th cranks (SRAM Exogram.) *Our rings do not mount to the new Ultra 6800/DA9000 cranks with their new custom asymmetrical BCD. They also work great with traditional 5-arm mount aftermarket cranks such as THM, Rotor, Cannondale, Specialized, LOOK and FSA cranks
SRAM — Buzz rings work great with the SRAM 10sp and “SRAM 22″ 11sp chain drivetrains when mounted to both traditional 5-arm SRAM cranks, and now work with 4-arm w/hidden 5th SRAM Exogram cranks. They also work great with traditional 5-arm mount aftermarket cranks such as THM, Rotor, Cannondale, Specialized, LOOK and FSA cranks.
- eTap – Yes, our rings work great with eTap.
- YAW FRONT DERAILEUR – Yes, our rings work great with SRAM “Yaw” front derailleur.
CAMPY — Our rings work great with Campy 10/11sp chain and drivetrains (EPS included.) These new Buzz rings are made to be mounted on either traditional 5-arm cranks, and now work with 4-arm w/hidden 5th cranks (SRAM Exogram.) *Our rings do not mount on Campy cranks with their proprietary Campy BCD/Design. Example…you would use a 3rd party crank like a Specialized, THM, Rotor, FSA, SRAM etc crank with our rings and then the chain and derailleurs are Campy.
