Chainrings

- DualHex kits: 5mm-broach bolts with 6mm-broach nuts for secure 2-wrench assembly - Triple kit can be used on 5-arm or 4-arm mountain/road cranks (includes 5 inner chainring bolts in addition to middle/outer bolt/nut set)

- Drivetrain Speeds: 11 - Chainring BCD: 110 Shimano Asymmetric - Material: Aluminum

- New 3D composite chain ring teeth composition is optimized for chainwheel load out

Shimano XTR M9000 11-Speed Chainrings - Chainring BCD: 64 Shimano Asymmetric - Drivetrain Speeds: 11 - Material: Aluminum - Ring Position/Type: Inner

The radical new look and feel of SRAM's X-SYNC 2 Eagle chainring is a direct result of SRAM drivetrain engineers studying the performance and wear characteristics of thousands of X-SYNC chainrings. The longer, positive-rake tooth shape has been designed to work perfectly with the Eagle chain to increase chain retention and overall pedaling efficiency, while decreasing friction, noise and wear. - Can be used with Eagle 12 speed or SRAM 11 speed chains - Direct mount rings with 3mm offset fit Boost geometry Eagle cranks; direct mount rings with 6mm offset fit traditional geometry - Eagle cranks and GXP spindle XX1, X01, X0, X1 and X9 cranks
