Praxis Works Buzz Chainrings - 130 BCD

This Praxis compact 130BCD road chainring set is engineered for the highest performance shifts in all conditions. LevaTime® performance and proprietary forging process give the fastest shifts and longest lifetime of any chainring on the planet. Compatible with Shimano (Except the new Ultra 6800/DA9000 cranks with their new custom asymmetrical BCD). Sram and Campagnolo (Except on Campagnolo cranks with their proprietary Campagnolo BCD/Design, you would need to use third party cranks). These Buzz Rings also work with eTap and the Sram Yaw front deraileur.


  • Updated “Buzz” design for both traditional 5-arm and Sram Exogram with the hidden bolt
  • Now including long and short threaded catch pins (Buzz Rings only)
  • Cold Forged and Hard Anodized 7075-T6 Aluminium
  • Work with Shimano™ 10/11 or 12 Campagnolo 10/11, SRAM 10/11 drivetrains
  • We highly suggest KMC, Shimano™, or Campagnolo chains
  • Not compatible with Campagnolo 5-arm or 4-arm as Campagnolo has proprietary bolt pattern
  • The Praxis compact 130 BCD chainring is great for use with Di2 or EPS systems
  • InfoCrank, Power2Max, SRM, and Quarq power meter compatible
  • Tooth profiles all Cold Forged
  • LevaTime® shifting technology
Mr RoseLove these chainrings. Perfect shifting with Di2.
StuartSame weight as the rings that they replaced despite looking like they would be heavier due to the design, nice finish, choice of two length chan drop pins . Shift as good as anything else I`ve tried
