STONE 104BCD Chainring Spider Adapter for SRAM 3-Bolt Direct Mount Cranksets (X9, X0, X01, XX1)

The STONE chainring spider adapter bridges SRAM’s 3-bolt direct mount interface and the widely used 104BCD chainring standard, giving your existing crankset access to a much broader choice of chainrings.

By converting SRAM 3-bolt direct mount cranksets to the 104BCD standard, this adapter lets you pair your crankset with a wide range of 104BCD chainrings instead of being limited to direct mount options.

It is designed for 1x speed drivetrains and is offered in three offset versions—0mm, 3mm and 5mm—so you can match different frame geometries and chainline requirements.

Each adapter is machined from high-strength Aluminum 7075-T651 using a precision CNC process and finished with an anodized surface for lasting durability.
