3 cross or 4 cross

[Glen]

Am I right in thinking this is 4 cross spoke pattern?  seeing as 4 spokes cross eachother?

[SaMAlex]

Yep 

[mileyboy]

what length spokes are they? 194?

[SaMAlex]

thanks, so im also right in thinking most bikes today use this 4 cross pattern?

I think alot of bikes use 3 cross cos they are easier to build / easier to replace spokes.
4 Cross is said to be stronger, but I dont know how much difference it really makes.

isn't 3 cross with 184 sized spokes and large flange hubs?

I've built all my wheels with large flange like this and then used 194 to lace up small flanged hubs with a 4 cross patern

I've used the spoke length calculator on here.
You can select rims/hubs from drop down boxes, or input the data into he boxes.

Four cross means follow one spoke line and it should cross four other spokes. Your wheel is laced 4 cross, you have missed one intersection nearest the hub.

[SaMAlex]

Your pic isnt right. You have missed off a red oval on the tiny cross right at the hub. They bearly even "cross" but it counts

The green oval isnt to do with the "Cross". Thats just cos they are laced in mirrored pairs.

Please post a pic of 3 cross

It just so happens that I have 4 (New school) wheels in my car today, and they are ALL 3 cross!

Pick a spoke and see how many other spokes it crosses on the same side as the hub!!

If its 3 its 3 and if its 4 its 4.

4 cross will use longer spokes because the hub will be twisted more than 3 cross!!

3 cross pattern


4 cross pattern

[kuwahero]

in simple terms

3 cross - goes under two spokes and over one

4 cross - goes under three spokes and over one

on same side of hub

on same side of hub

I think I'm right in saying that normally 36 spoke wheels are laced 3 cross & 48 spoke 4 cross?

[moley]

Low flanges should accomodate 4 cross.

High flanges tend to have less crosses.

Most 48's are probably 5 cross (I think)

[moley]

The more spokes a wheel has, the higher the cross number for a similar spoke angle. 48 spoke wheels are usually built cross 5, 40 spokes, cross 4; 36 spokes, cross 3 or 4; 32 spokes, cross 3; 28 or 24 spokes, cross 2...

In the case of unusually large hubs, particularly large hubs in small rims, fewer crosses are often indicated, to avoid bending the spokes where they exit the nipples. For example, the Rohloff Speedhub has 32 spoke holes, but is usually laced cross 2.

just get it right glen ,,,,this was my last effort  went for 3x
