I need a new crankset to replace my Sram Non-DUB GX crankset. But, I would like one that will fit my collection of Sram x-sync chainrings. Will the sram DUB cranksets fit these? If not, is there another brand of cranks that still use the Sram x-sync chainrings? I already own a bunch of these chainrings, so hope to be able to keep using them on my new crankset.
