Trueing Problem.

Easy guys,

I'm not a noob to building wheels, seeing as I have been doing it for 1 year or so. But when my dad was up north the other day, he popped into tarty for me, to get some new spokes. As I had snapped 4 within a month, and these were spokes off an 07 t-pro, which had been built up multiple times.

I have built it up trued it, but ever 2 spokes, there are 2 spokes sticking up further. Please tell me what I have done wrong. :L It is a echo urban rim and onza t-master hub, 36h and 3cross.

Thanks.

It's not laced quite right, what you have done is laced one side of the spokes offset one hole from the other. If you can get a decent photo I can show you what needs to go where (Y)

Yeh, defiantly laced wrong. I did the same before (copied a guide for a 36h instead of 32h)

http://www.trials-forum.co.uk/wiki/How_to_build_a_wheel - See if you noticed anything you did wrong.

EDIT:

On the left picture that's how your spokes are with the two green lines (kind of parallel) it needs to be the same at the other side like what i made up in red.

I don't know how to explain how to do it because i haven't made them in a while but i know it needs to be like that. (Y)

Hmm, but that means it would be laced into the wrong eyelets on each side of the rim.

Its hard to be sure from those pictures, but I don't think you've laced it wrong. Could be the spokes are for 4x instead of 3x? You could look up the dimensions of your hub and rim on tarty and whack them into a spoke calculator, then you can see what lengths you need for 3x, 4x etc and compare them to your spokes.

I give up.

Rebuilt it all, still the same?

I'm actually gunna put my foot through it in a minute.

Just uploading pics now.

Cheers - the problem is as I thought, one set of spokes is offset the wrong way in relation to the other.

If you look down the centre of the axle, the head of the 'blue' spoke is one hole to the right of the head of the 'red' spoke, but they enter the rim in the opposite formation (blue spoke to the LEFT of the red spoke). This means the blue spoke has to reach further than it should (so appears to be too short) and the red spoke isn't stretching far enough (so appears too long).

Basically you need to move all of the spokes on one side of the wheel round two spoke holes (in this case, blue spoke needs to go from position 1 to position 2... then the spoke that was in 2 needs to go to 3, etc).
