STONE 64BCD Spider Adapter with Guard for SRAM 3-Bolt Direct Mount DUB Cranks (XX1, X01, GX, NX) – 22T–26T Chainrings
The STONE 64BCD spider adapter with integrated guard is built for SRAM 3-bolt direct mount cranks. It converts the crank to a standard 64BCD 4-arm chainring interface with a 10mm inner offset, allowing the use of small 22T–26T chainrings — a setup mainly found on BMX bikes.
This STONE spider adapter is designed for SRAM 3-bolt direct mount cranksets. It converts compatible SRAM 3-bolt cranks to a 64BCD 4-arm chainring interface with a 10mm inner offset, making it suitable for small chainrings such as 22T, 24T, and 26T.
