Spokes

If you're building radial or full crows foot you can choose whether you go inside or out.
Obviously the radial pic isn't the best bc the back of the hub is slotted, but you get the idea?

This what I thought, and preferred heads in, for the extra bracing angle. It could be the shape of the spoke head thinking about it. But the inside drilling does look fecking narrow. Havent had a chance to cheak the rear hub yet.
