105 5800 axle material

Have yet to tear into a 105 5800 hub and need to know if the axle is steel or aluminum. Anyone have info on this? Was able to find a schematic of the hub, and from the looks of it the axle could be either material.

My 6700 Ultegra are steel. I can’t imagine 105 to be aluminum

My 6800 threaded axles were steel, I'd assume the 5800 are too

This was in my mind too, but the OP didn't seem to want to tear into his hub. On the 105-5800, you have to completely remove the steel lock nut to get to the axle to test. Personally I would have done this instead of trusting BF pundits.

Speaking as a pundit wannabe: The 105-5800 hub I had in my parts bin has steel axles.
