SRAM makes 2 versions of the GXP GX1000 crank, one for conventional rear spacing and one for Boost. Boost frames, hubs and cranks have a wider chainline than a conventional mountain bike drivetrain so while it will "work" on a conventional frame it will not be ideal. This version of the GX 1000 crank however is designed to work with a conventional rear MTB spacing and will work great with your non-boost frame.
