Praxis Works CR 110 BCD Aero TT 52/36

• SHIMANO - Our Praxis time trial chainrings work great with the new Shimano 10/11sp chain and drivetrains (Di2 included) when mounted to a traditional 5-arm mount 110 or 130 BCD Shimano crank. They also work great with traditional 5-arm mount aftermarket cranks such as THM, Rotor, Cannondale, Specialized, LOOK and FSA cranks… *Our chainrings do not mount to the new DA9000 crank with its new custom asymmetrical BCD.
  
  SRAM - Our chainrings work great with the SRAM 10sp and 11sp drivetrains when mounted to a traditional 5-arm mount 110 or 130 BCD SRAM crank. They also work great with traditional 5-arm mount aftermarket cranks such as THM, Rotor, Cannondale, Specialized, LOOK and FSA cranks.
  
  EXOGRAM RED/FORCE/RIVAL CRANKS - Our rings are not made for the brand new SRAM 'Exogram' cranks as they are a custom 4-arm mounting. -YAW FRONT DERAILLEUR - Our rings shift great with the new SRAM " Yaw" front derailleur.
  
  CAMPY - Our rings work great with Campy 10/11sp chain and drivetrains (EPS included) when mounted on a traditional 5-arm mount 110 or 130 BCD crank such as a THM, Rotor, Cannondale, Specialized, LOOK, FSA crank. Our rings DO NOT mount to Campy cranks.
  
  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 custom 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, the Praixs time trail chainring's precisely located scallops help control chain movement and prevent chain suck.
