BMX spoke tension
Are spoke tensions on BMX wheels lower than other wheels? I bought a used wheel off eBay and the spokes are tensioned to 10 on my Park TM-1 tensionometer, 17 is 51 Kgf. I think regular wheels are in the 100s Kgf.
If I wanted to used the wheel for road riding should I go for a higher tension?
I also posted this on the bicycle mechanics board.

Uhhhhhh. I'm not wheel builder but i can decently true wheels and i would say that you should keep the tension in your spokes the same as you would any of your other bikes...
But i'm not too sure...

now i don't know it you have eyeleted rims or not? also, are you sure you calculated the park tension meter number correctly? i am assuming you noticed that it matters what kind of spoke it is-- double butted vs straight and diameters...
without knowing your specifics, i would tentatively say you need to crank those up to around 20-25ish on your Park tool or so. if you want i can go measure mine again. i don't recall the exact tool reading. but i do know that they were a simple no-dish build so all the spokes were equal.
i don't think it matters much about road riding...it sounds like they are not tensioned enough. you can contact the rim manufacturer to ask them. i would imagine if you have eyelets than it would be about the same as mine.

Hozan has one...
Wheelsmith has one (down the page a bit)...
Check out Sheldon Brown's page on wheelbuilding or try Schraner's Book on the subject (but he talks about some REALLY technical stuff...more than I cared for)

it seems to me that many rims are similar. my builds have all been from about 80 to110 kgf. the delicate XC rims being on the lower end for example. then eyelets are another consideration. i think atomlab gets away with no eyelets because the rim is thicker there, but don't quote me on that.
the rim manufacturers will always tell you the recommended kgf if you email or call them.
for calculators, i prefer the DT swiss calc at their homepage. it allows you to store your builds and pull them up in the future. i have yet to run into accuracy problems with it.
for lacing pattern, i have to admit i did use the color diagram guide on sheldon browns page.
i highly recommend you try building a wheel. very satisfying.

Keep your spokes tight. That's all you need.

I built a Primo bomb laced to a Alex MX22 or something, cant recall how many cross.
It was so annoying. I wanted to fill a pillow sack with baby kittens and beat grannies with it.

Just my $.02

spoke tension depends on the rim, usually. Laceing a wheel is easy, tensioning properly is the hard part.....I really wanna try to lace one up blind folded...just for kicks

I tighten them til they are very snug, then I lay the wheel on its side and stand on it, flip over and stand on it again to "bed in" the spokes, then give it once around with the spoke key again, i dont have a $_____ spoke tension tool. but I build a strong wheel.
