  • 48/32 110BCD VIP NOTE: Our 110BCD spiders have custom designed mounting tabs that allow our 48/32 110BCD to be installed.  This spider tab design has been adopted by Cane Creek, Bingham and Specialized and our 48/32 can only be installed on these.   So please make sure you have one of these cranks/spiders! These specific sets include custom ring bolts required for installation.  This set will not install on prior generation “TURN” road cranks or other brand cranks.  Also, it will not install on spider based power meters such as Power2Max or SRM.


  • SHIMANO – Praxis rings shift great with both Di2 and mechanical Shimano 10/11sp drivetrains.

  • CAMPY – Praxis rings shift great with the EPS and mechanical Campy 10/11sp drivetrains. These rings are not compatible with Campy 5-arm cranks as they have proprietary bolt pattern that is not 110BCD or 130BCD
