• Need some help fitting a Sram GX dub crank to a voodoo. Voodoo has a FSA BB-7420 73x113mm shell. Bike is going to 1x 12 speed. Can someone recommend what bottom bracket I should be fitting here to achieve a good chain line?

  • External BBs don't have the spindle requirements like BBs of old.

    Look for BSA SRAM DUB BB (incidentally, thats what the Prime hub posted above I am trying to figure out the BB tool required) they will be 68/73, with associated spacers.

    The cranks will have the spindle attached already, and you want a narrow wide chain ring to keep the thing aligned.

    Watch out for boost spaced rear wheels, they need an offset chain ring for the wider rear.
