truing wheels...should the tension be the same for all spoke(8 posts)

truing wheels...should the tension be the same for all spokeishmael
Mar 10, 2002 9:01 AM
after finishing truing my kyseriums the spokes now have different tensions (when i hit them a few make low tones) it possible to get all the spokes equally tensioned and is it worth it...

On the front wheel, all spokes should be of roughly equal tension. There will be some variation due to things like the rim joint. On the rear, the drive side spokes should be roughly equal, and the non-drive side less tension, but roughly equal to each other. Again, there will be some variation. How much variation is a testament to the abilities of the wheel builder/truer and to the quality of the starting components. It is impossible to tell from your statement whether you have a problem. Too much variation will make the wheel unreliable and it will require truing freqently and possibly break spokes. You need an experienced wheel builder to look at the wheels and tell you if you have a problem.

the differences in spoke tension arent extreme (front wheel) but id like to try and get it as even as possible if i can..if i have a looser sounding spoke is it possible to tighten the two nearest appossing ones and then tighten the looser one..i have a fear that with the few spoked radially laced wheel (kyserium) it will just end up with a wheel with a slight bump at each spoke..

If you tighten all three of these spokes to raise the tension, you then run the risk of creating a flat spot in the rim. If you have a hop there right now, then tightening the three will help with "roundness." Again, without knowing how much difference there is (compared to a properly tensioned and true wheel) it is not possible to advise.

Did you use a truing stand for truing the wheels? Did you check radial true as well as lateral true? Did you check to see that the rims are centered? If a rim is bent even slightly you won't be able to reach equal tension on all spokes.

next time...thanks

I kind of stalled on answering this question because I wanted to give an adequate answer without writing a book. First: In a perfect wheel, every spoke would have exactly the same tension. Second: There are no perfect wheels. Every wheel will have minor individual differences in spoke tension.

So how bad is bad and what to do about it? Most anyone can adjust minor wobbles out of a wheel. I'm not talking about that today. Adjusting tension can be a different thing. Obviously, if you have spokes that are WAY loose, they should be tightened to be approximately equal to the other spokes before you do anything else with the wheel. If you have several loose spokes, the best thing to do is to loosen every spoke until you can see one thread and then gradually rebuild the tension evenly back into the wheel.

Just tinkering? I'm from the "If it ain't broke don't fix it school." Every time you adjust the tension of one spoke, it affects the tension of every other spoke. That's why, when you get to the final trueing process of a wheel, eventually you reach a point where you seem to be going in circles. Part of the art of wheel building is knowing when you're done.
i shouldve gotten a truing stand firstishmael

it really wasnt bad and now after about 2 hours both wheels are about as true as before but with more tension in the ones that needed that makes it successful i guess but i fear that all my tinkering is going to start to show through soon, theyve been good for a year so if they start doing things now ill know it was because of me
