Basic bike mechanics- I am curious to know

(Since it s related to C&V bike so I post it here, but if it s wrong please admin remove it. Thank you)

Hello all,

I am curious to know how you do the reassembly.
I have two photos of cone nuts/bolts in the front and rear hubs of my bike.
You can see in the lock nut, there are two different designs on its side/face: one is flat (pic 1), the other is not.

The way to assembly proper is :

#1_ cone nut first for sure, washer, then lock nut with side 1 touching washer.
#2_ cone nut, washer, then lock nut with side 2 touching washer. ( for me, I do this)
#3_ Cone, washer, lock nut , either way, does not matter, it doesnot make any different.

Some of the bikes that I opened, it s in the way #1.

What is your way?

#2 - The ring on the outside of the lock nut is for gripping the dropout.

The ringed side of the lock nut goes against the dropout, the flat side goes against the washer.

Before you tighten the lock-nuts, make sure the axles are centered in the dropouts

just for the sake of extra info, some hubs have locknuts with a lot of texture for gripping the dropouts. This is especially useful for rear dropouts, and especially when they are chromed.

Here's a shot showing the locknut on a Campagnolo Record hub...

.
...unless there's something unusual going on, like a cone that has a worn surface, or a bent axle that needs replacement, I generally do not remove the hardware from both sides of the axle. This leaves me a reference point for reassembly, so the axles remain more or less centered where they were before. I just clean one side in place on the axle.
