STONE 76BCD Narrow Wide Chainring for Old SRAM XX1, Stout, and SiSL2 Cranksets (30T–40T, CNC 7075 Aluminum)

Overview

The STONE 76BCD Narrow Wide chainring is designed specifically for old model SRAM XX1, Stout, and SiSL2 cranksets. It is not compatible with FSA, ROTOR, or other 76BCD cranksets.

Machined from high-strength 7075-T651 aluminum alloy with precision CNC manufacturing and finished with an anodized coating, it delivers an ideal balance of stiffness, durability, and low weight.

Compatibility

To confirm fit before ordering, measure the distance between adjacent bolt holes on your crankset. The chainring fits cranksets with the following measurements:
