Compatibility / Chain
– 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.
