Title: Help please with these spokes
Post by: The Burner King on April 16, 2008, 09:21 PM
I have just sold these wheels to a new member on here and they were built and trued in a bike shop.

The member has been told by an expert that the spokes are not conventionally crossed and would be compromised with strength. As i understand there is a 3 cross and a 4 cross, I have had a look at other wheels and how they are crossed, and i cant see a lot of difference. Can someone tell me what cross these are from the pictures? I would say they are a four cross.

Any help would be appreciated.

Thanks Julian

Look like 4 cross to me  :daumenhoch:

Hmmmm after looking closer they look more like 3 cross  :)

They are 3 cross .... and there aint nothing wrong with 3 cross.
No strength compromise there, they are fine  :daumenhoch:



(maybe 4 cross is a tiny tiny bit stronger, but people use radial lace wheels (0 cross) and they are fine)

Thank you. I have had about 25 sets of wheels done this way.

Oh yes, I see. he is right. They are 3 cross, no problem.... but they arent "weaved" through the last lace. The first 2 crosses should go over-over and the last cross should go under (or the other way round).

Some wheels are build like this, its easier to do it, for sure. I dont think it will make a massive difference to the strength, as that comes from keeping the spokes tight.

I built my wheels by mistake in this way - didnt send the spokes over and under.

I rode it for weeks without a problem before I could be arsed to rebuild them. And I do mean rode it.

As for a strength compromise, I'd say it would be neglegible. My understanding of it is that the spokes are likely to remain tight for longer if they are crossed over and under. Not that bigger a deal in my book.

3 cross over - over - over lacing - yes it could be argued that they are not quiet conventional over - over - under - but the vertical tension comes from how tight the spoke is.

Theres nothing wrong with the lacing pattern whats so ever and they will stay true for ages.
