I can't tell if this is supposed to apply to my non-Prima hubs, but I tried it anyway to no avail. I can barely get a small screwdriver under the hub lip, but I can't pry the cap off.
Nono, that's not what they mean. Ever taken apart skateboard/rollerblade wheels?
Anyhow, you have two press-fit bearings, and between them is a spacer, or in Rolf speak - a floating axle. The floating axle is there to take the load when you clamp the wheel in place, it braces against the inner bearing races. So what you do is you insert something slender in the center bore of the wheel axle and poke the floating axle a tad sideways. Then you can get a drift punch to push against the inner bearing race and tap it out.
But if it applies to your hubs I can't tell.
