• It would be easier to use new spokes, you avoid having to keyhole the hub's spoke holes and you can choose your spoke length to suit your new hub, rather than the other way around. The concealed nipples aren't a big problem, just adjust the ERD in your calculation to suit.

  • would bladed spokes be ruled out without keyhole-ing?

    You need something where the major axis of the blade is less than or equal to the diameter of the spoke hole. With most hubs being drilled 2.5mm, you you can use any of the common 2.3mm blades, like Sapim CX-Ray, DT AeroLite/AeroComp/AeroSpeed. What you can't fit through a round 2.5mm hole is something with a 3mm+ major axis, such as DT New Aero or Sapim CX.

    Royce will keyhole their hubs, but for some reason don't do 18H
