H Plus Son - Spoke Tension

[Tony T]

What spoke tension are the builders here using for H Plus Son Archtype (24 hole rim) with Sapim CX-Ray Spokes?

Which rim? What spokes?

Yeah, that would help (I also edited the OP for this)

Archtype, Sapim CX-Ray

120 kgf max front, right hand rear. I shoot for 110 or so. On just about any aluminum rim and just about any spoke make or dimension or spoke count. Tension is tension.

Here's what I'm getting with my Park TM-1

You should get to well within the 15% limit.

I'm within 10% now (I've been working at it since my last post.)
btw, this wheel has about 10,000 miles on it.
Here's my final (for now) #'s
(I'll re-check after a few rides)

How does the left vs right tension look?

[ergott]

That looks good.

Thanks!

How much of a drop in kfg should be expected when the tire is mounted?
With a 25mm tire @ 90psi I get a drive side avg of 93 kfg (130kfg unmounted).

[Tony T]

BTW, sent an email to H Plus Son, they say to "keep it under 125 KGF"

Not much research has been done on just how much tension drop there is. I can tell you that some combinations of tire/rim are real bad. I've seen 50kgf from one rim/tubeless tire setup. It's all over the place.

Tire mfgs are not off the hook. They are not very consistent with the bead diameters from batch to batch.

[Tony T]

Thanks, that's good to know.

I would guess that even in extreme cases that the tension should still be done 'to spec' with the tire off the rim?

That's where there isn't a real consensus. I've bumped tension up a bit once tire was installed on my wheels. I've also started using a thread locker (mechanical from Sapim Secure lock or DT Pro Lock) more often. It's too easy to have NDS spokes go slack with the low tension ratio and tension drop when tires are installed.

[Tony T]

Is 'spoke prep' used when using Sapim Secure lock?
