STONE 144BCD Hollow/Aero 1x Spider for SRAM GXP 3-bolt AXS T-Type 8-bolt, for ROTOR, for Easton, 7mm inward Offset

Crank Compatibility by Interface

3-bolt version: for SRAM GXP-style 3-bolt mounting. Listed road fitments include compatible BB30/PF30-spindle versions of Force 11-Speed, Force 22, Rival 11, Rival 22 and XPLR. Verify the actual crank mounting pattern.
8-bolt version: for SRAM AXS/T-Type-style 8-bolt mounting. Listed road applications include Force AXS 12-Speed, RED AXS 12-Speed and Rival AXS, and compatible road power meter cranksets compatible with Quarq. The shared interface name alone does not confirm every crank and chainline combination.
Version for ROTOR: listed models include KAPIC, Hawk, Raptor, inPower and the newer 2INpower version. Aldhu and Vegast are also named in the product information; check the exact interface and offset before selection.
Version for Easton or for Race Face-style interfaces: listed models include EC90, EC90SL, XXE and GP3, with fitment dependent on the matching road-crank interface.

Installation and Chain Compatibility

Check the crank interface, chainring mounting pattern, frame clearance and required chainline before ordering. The 7mm spider offset is not a complete chainline measurement. Use only a matching single chainring; this spider does not support double chainrings.

For SRAM AXS Flattop 12/13-speed or T-Type chains, fit a chainring with the appropriate tooth profile. The spider itself does not determine chain compatibility.

Package Includes

One STONE 144BCD chainring spider in the selected interface and style.
