The absoluteBLACK SRAM BOOST 148 3mm OFFSET oval chainring has a special 3mm offset converting any SRAM crank into the specific Boost148 setup needed on Boost-equipped bikes. Boost and non-Boost SRAM cranks are identical. All shifting is achieved through the chainring itself, so you can use any SRAM crank for this conversion.
