David Posted September 20, 2006 Report Share Posted September 20, 2006 Hey, Ive been building my new rear wheel (521 on hope bulb) and its really starting to annoy me now. I have laced the wheel perfectly (3 cross) and started tensioning the spokes, first of all doing 2 turns on each. Once ive gone round the wheel a few times putting the same amount of tension on each spoke the wheel goes all over the place Like really badly swaying side to side. Im using 260mm spokes for both sides as I used the dt swiss spoke calculator which said 259.2 and 259.7. Ive never had this problem before Quote Link to comment Share on other sites More sharing options...
Tall_Rob Posted September 20, 2006 Report Share Posted September 20, 2006 Take it al off and start again.Your going wrong somewhere between getting it all together and tightening up the spokes!Try less turns till you build up tension.And don't forget..... Building a wheel from new doesn't always get straight instantly.Some tweeking may be required.Advise getting a spoke tensioner tool (lets you see how much tension their are under). rob Quote Link to comment Share on other sites More sharing options...
Dan6061 Posted September 21, 2006 Report Share Posted September 21, 2006 When I built my wheel, I could of sworn I got the lacing right, yet there was spokes poking out every hole, and it bounced about like a kid on a trampoline!Once I'd laced it properly, i tightened up all the spokes exactly the same! Yet it still had a hop in it.I managed to make the hop (up and down) not as big, and there was no side-to-side buckle. So I left it at that. I built it so all the spokes were as tight as they could be. - It's bloody strong! Quote Link to comment Share on other sites More sharing options...
nmt_oli Posted September 21, 2006 Report Share Posted September 21, 2006 If spoke length is correct, and lacing is correct, the wheel should come into true fairly naturally as you tension, mine always have.If nessesary, start again. Even though the spokes seem really slack, dont turn more than a whole turn at a time, even at the beginning. One turn, each spoke, keep working round. make sure there all equal before you start that though, ie the same number of threads showing below each nipple.

F-Stop Junkie Posted September 21, 2006 Report Share Posted September 21, 2006 I built it so all the spokes were as tight as they could be. - It's bloody strong!Common misconception - tighter spokes = stronger/stiffer wheel. It's just not true.A wheel has an ideal spoke tension where it's strongest, anything more or less and it's weaker. Quote Link to comment Share on other sites More sharing options...
David Posted September 21, 2006 Author Report Share Posted September 21, 2006 Im deciding wether to start again, seems a bit stupid though as Ive checked every spoke and it all seems to be laced perfectly. When I built it at first I just did 2 turns on each spoke, do you think I shud do all the trailing spokes so you just cant see any thread then put the leading spokes in like normal and tension them the same as the trailing ones?Thanks,Dave Quote Link to comment Share on other sites More sharing options...

Sorry, I didn't mean it was strong becuase all the spokes were as tight as possible..I tightened all the spokes as tight as I could thinking it would prevent me from having to tru it all the time.And I've barely touched it since I built it.It is strong though...
