3 cross or 4 cross

<< < (3/3)

fugazi:
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.
