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 11sp 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 – Praxis rings work great with eTap.
- Yaw Front Derailleur - Praxis rings work great with SRAM “Yaw” front derailleur.
CAMPY - Praxis 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). *Praxis 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 Praxis rings and then the chain and derailleurs are Campy.
