The Original one and only absoluteBLACK premium Sram compatible Direct mount BOOST148 1X Oval narrow wide chainrings are designed for GXP and Long BB30 spindle cranks. Chainring is dedicated for Boost148 bikes ONLY. Converts a regular Sram crank into a Boost specific setup. (3mm offset). They are also 100-percent optimized for Eagle.
This oval chainring with special 3mm offset converts any Sram crank into Boost148 specific setup needed in Boost equipped bikes. Boost and non-Boost Sram cranks are identical. All the offset is achieved by the chainring itself, so you can use any Sram crank for this conversion. Our regular OVAL chainrings for gxp cranks have 6mm offset whether this one has 3mm, but both chainrings look very similar.
