Chainrings

- CNC machined 7075-T6 aluminum with modified shift gates and special profiles to allow flawless shifting with 9sp and 10sp drivetrains - Middle and outer chainrings have strategically-placed stainless steel pins to further enhance shifting - 5mm thick middle ring, 4mm thick outer ring - Anodized black with laser-etched graphics

- Shimano, 38T, 8 sp, BCD 104mm, 4-Bolt, FC-M361, Middle Chainring, For 28/38/48, Steel, Black, Y1KN98040

FSA's Pro Road chainrings are made from CNC-machined 7000-series aluminum for low weight. The teeth are ramped and pinned for excellent shifting, too.

Original equipment on SRAM and Truvativ cranks, they also work well with other drivetrains. - 7000 series aluminum provides strength and durability - 130mm BCD

- Truvativ, 48T, 9 sp, BCD 104mm, 4-Bolt, Outer Chainring, For 28/38/48, Steel, Black, 11.6215.018.000

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
