I was cleaning my old bike and discovered my rear wheel is a little untrue. More importantly I noticed a pair of spokes on the drivertrain side do not contact at the crossing point.

The wheels are Mavic Open Pro with Ultegra hubs. It was a second hand wheelset that I brought from ebay.

Should I be concern? I was able to get wheel true with the spoke ranch but I'm concern if it is ok to ride.

I looked at my wife's bike and see all the spoke crossed and contact (on driver side). while mine has one pair of spokes that have an open contact. Any suggestion on how this can happen?

Thanks.

do they overlap in the same way as at the other crossings? they might have been threaded through each other funny. How untrue is the wheel? A mm or so isn't a big deal, but a cm is a lot.

thanks for your reply. the wheel is off only about a mm or two.
I guess, my thought is that should they be crossed and contact in order to distribute the force load? And by them [the pair of spokes] not in contact will it effect the whole wheel weight distribution?

It's kind of unusual-- Is the wheel out of round? Do the spokes on that side all feel like they have the same tension? It's hard to tell by feel, but if any are especially loose it would be noticeable.

Might be a couple of spokes that were replaced by the guy that sold them on ebay. Like BD says, maybe he laced them differently.

Check the pattern compared to the other spokes. Over over, under?

Gina has similar OP type wheels on one of her bikes. From the hub is over over ,under. The last cross touches, the other two closest to the hub don't.

If it's a problem, it will more than likely start coming untrue everyother time you ride it. I've never had a wheel explode under my weight so shouldn't be dangerous for you to ride it. IF it continues to go crooked, maybe have it relaced with new spokes, about $60....$20 for spokes, $40 for labor.

I got another question...
I'm shopping for a wheelset and saw an ebay post stating "rebuilt" wheels.

What exactly does a rebuit consist of ?
When/why do one needs rebuild a wheel?
and what would a 2nd owner or in this case posibble future 3rd owner need to be aware of such buy?

Appreciate for any feedback.

Well, these are my thoughts. Not sure if they're accurate or not though.

They may have failed and the owner took it apart (or sent it back to the manufacturer) and rebuilt it. Or based on the feeling I get from the wheels section in RBR, the knowledgeable owner took it apart intentionally right after they get a machine-built wheel from the store, and rebuilt it by hand.

If the wheelset is the pre-built type, like the Mavic Krysiums, then I would be concerned. I would think that those normally don't need to be rebuilt unless it's a lemon or it went through abnormal stress.

If it's something like an Open Pro, then it can be either, though I think it's more likely something broke that caused the rebuilt. I don't think the majority will rebuilt it by hand as soon as they get this type of wheels.

I guess the owner didn't mention anything regarding why it was rebuilt?

Thanks Dave.
Nope, the seller didn't mention anything other than it was rebuilt.
BTW, it is a Shimano Dura Ace Wheelset WH-7700
After doing a little search, I dont think that might be what I'm lookin for.
Oh well, the search continue... Thanks again Dave
