This isn't the first set of wheels I've built, so I was confident when I ordered the spokes. But they are too long and I'm about to sell all my equipment and never build another wheel!

If you have a moment, can one of you guys tell me what length you would order?

Nashbar high flange track/road hubs (nf-ghr2) 130mm spacing on the rear, 120 front
Sun Rims CR 18, 700c rims

I used spocalc and the dt swiss online calculator and they both came out with the same dimension.

I am really disappointed. The spokes were the most expensive element.

Soil_Sampler

there is one mistake.

I measure my own hubs and rims, then compare to online numbers.

Sun shows a 612 erd.

How many crosses? Assuming 3-cross, I get 296 for the front and 292 for the rear.

The front hub OLD is 100mm, not 120mm.

Pretty clever of them to include spacers for either 120 or 130 OLD on the rear.

The one problem I noticed is that spocalc shows 62 for the dL and dR for both the front and rear hubs, but the Nashbar website shows 64 for the rear hub. If you ordered based on spocalc's 62 for the rear, they'd be long.

Man I swear, sometimes using spocalc is as good as guessing.

DLBroox

Oh, I forgot to mention it was a 3 cross.

I ordered 296 for both front and rear. I laced the rear first, so I guess if I had started with the front I wouldn't have noticed until I did the other.

Thanks for checking. At least I know I wasn't completely off. I thought I did measure myself, but now I'm not sure. Very frustrating!

Would someone be able to trim them and redo the threads?

Coming up with the same size for both front and rear sets of warning bells to me. I have always found a difference in spoke length, even with track hubs. Usually at least 2mm shorter in the rear.

Soil_Sampler

I come up with 296-295 on just about every calculator.

Scoop, the only way I can get 292 is with a 611 erd and a 16mm nipple.

dabac

So you got 296 for both wheels and you need 292 for the rear.

What nipples are you using? Any chance of dropping one notch in nipple length to compensate for the long spokes?

How 'bout going to 4X on the rear? Depending on flange height and spoke number that'll eat up some extra mm. You might find another match by both going up in no of crosses AND in nipple length.

Spokes CAN be cut and rethreaded, "all" you have to do is; find a bicycle store that has the required machine, isn't too busy to tackle the job, and is nice enough not to charge you an arm and a leg to do it...

DLBroox

I ordered based on 62 dr and dl for both wheels. I don't remember seeing 64 anywhere. So basically it looks like spocalc fills in 62, right? I did find my old calculations. I must have plugged spocalcs 62 into Dt Swiss's system and got the same result.

How do you lace a 4 cross anyway?

Soil_Sampler

you don't want to 4X a 32H hub.

urbanknight

^ Correct. Bad idea.

DLBroox

ok, now I really don't know what to do. I remeasured the hub and the dl is 62. I ordered these spokes a couple of months ago, so I just didn't remember if I had measured them in the first place, but now I remember I had. So, either the spokes are the wrong length,and they won't work with the front either, or I don't know...

Soil_Sampler

most important measurement is rim erd.

Hubs-you measure center of spokehole to center of spokehole.

each spokehole is 2.4-2.5mm, so if you don't measure correctly you can be off several mm.

nashbar shows 64.

dabac

Doesn't have to be, it depends on flange height. High flange is likely to cause spokes to overlap spoke heads, which might cause extra wear(on the spoke) and is awkward if a spoke has to be changed. '
But apart from that there are no particular drawbacks to 4X.
No particular merits either, but if it meant the difference between using or discarding a set of already bought spokes I wouldn't hesitate.

Theoretically it'd mean a very minor reduction in lateral rigidity, but I don't think it'd be noticeable either way.

dabac

I'm writing this w/o immediate access to a wheel to look at, so you might have to check my numbers...

If you look at an wheel that's laced X you'll see that there are pairs of spokes that are running pretty much parallell, one heads-in, one heads-out. For a 3X this is every 6th spoke. So if you have one spoke that's heads-in, then the heads-out "parallell pair" buddy would be in the 5th hole from there. For a 4X it'd be every 8th spoke. The sequence at the rim is the same for all no of crosses.

DLBroox

I know you've said Nashbar lists it as 64, but I measured, and I do know how to do this correctly. It measures 62.

Soil_Sampler

ok.

you seemed unsure, hence my response. good luck.
