Exage HB-RM50 front hub
Hello all,
I am fixing up a Trek 850 Antelope. It has an Exage HB-RM50 front hub. The cones are shot.
I found on this store:
Shimano Hub Cones and Axles Front - Buy Online - MoruyaBicycles.com.au
That the cones I need are Shimano part number Y23104000.
That store is in Australia. It looks like I could potentially get replacements from this place too:
Wheels Mfg Hub Cones
Any other suggestions?
Also: each side had 11 3/16" balls in it, making a total of 22 balls. Is it supposed to be like that? Did someone rebuild it at some point and add two extra balls, or did some come like that?
Thanks!

This states 10 balls/side.
VeloBase.com - Component: Shimano HB-A550 / FH-A550, RX100
I'd expect that count too, from that era.
You might look at-
Husky Bicycles Bicycle Hub Axle Shimano RM50 Front 140mm Bolt-On
I've had good service from them, but can't really attest to quality, since they are in my spare parts bin or gone on CL flippers.

I found a NOS pair on ebay. That's probably my best bet, isn't it?
