Slotted front axles, how come?
Why do some quick-release front axles have shallow lengthwise slots machined into them for keyed spacers while others don't have slots and use round spacers? Just wondering.

Anytime you see a keyed washer, the designer of the piece wanted to resist rotation, so you have to think "why?".
On a hub axle, it makes an easier job to adjust the bearings.
"Why?" on some axles there is no flat or key? Price.

How so? To keep the lock nut from moving the cone when locking?
I just had to unfudge a slotted washer out of the headset of a Fuji last week... so they seem like a pain to me
I ended up locking the nut against the cup, and then rotating both the cup and nut together until the washer was dragged into the right position. Probably the reverse of how it originally got fudged.

I think that comes about from the reflector bracket dragging the washer with it. those fudged up washers are another reason i always like atleast 2 washer/spacers in a headset.

As to price, I just repacked a couple of hubs--a Shimano 105, which has an unslotted axle, and an unlabeled Shimano hub--which I assume was a cheaper model--that DID have a slotted axle.

the slotted washer keeps things from rotating and does make adjustment marginally easier. Probably best to put the axle in an axle vice.
