Digging through a spares box, preparing for my first oil change, and came across 6 new spokes supplied with my Raven.
unused and sellotaped together.
I notice one had a strange end to it.
I am not up on spokes at all so could someone please comment?
A couple of snaps to give you an idea of what I have.

Lower left again. Appears to have something like a mushroom head to it

Ah ha the mystery spoke i can tell you straight off before the experts come in.
I have no idea. ::)jags.

That odd-looking spoke is the other end of that one spoke, Matt; what you see is the nipple screwed onto the threads. The others should look the same at the other end.
All the best,
Dan.

He's sending you up, Dan.

Sorry Dan. I usually follow you but not this time.
One spoke is definitely different.
I think

Matt,
I know not everyone is equally inclined mechanically or equally familiar with bicycle components, so I always try to answer genuine requests sincerely. Maybe it is the teacher (former university professor and professional bicycle tour-group leader) in me that values education and access to it, so I'll have another go.
Matt, the spokes in your wheels have two parts:
a) The spoke itself, with a hooked bend and head at one end and rolled threads at the other, joined by a shaft.
b) A nipple. This usually has four sides or flats, and serves like a "nut" to thread onto the threads at the end of the spoke. Once the spoke and nipple are assembled in your wheel (between hub and rim), turning the nipple with a wrench takes up slack and tensions the spoke properly, making your wheel stiff and ridable. A spoke nipple looks like this: http://en.wikipedia.org/wiki/Spoke_nipple
In your bundle of six spokes, you should have a nipple screwed onto the end of each spoke. It looks to me like one spoke/nipple compo has been reversed compared to the others when they were taped together -- your photo shows a bunch of spoke heads and one nipple on the end of a spoke. That's the only difference I see. At the other end, you should see a bunch of nipples and one head.
Best,
Dan.
