Hello,
I recently bought a track hub from a small company, that specifies they should only be laced with a 3x pattern, as the hubs come with grooves for the spokes to sit in. Here is the product link : [https://mentalbmx.com/product/mental-track-tricross-rear-hub-fixed-fixed-gear/](https://mentalbmx.com/product/mental-track-tricross-rear-hub-fixed-fixed-gear/)
I tried following the provided pictures and instructions as closely as possible, and my spokes definitely don’t sit in the grooves on either side. I am wondering if I am missing something or if the hubs should be laced on a 2 cross pattern.
Thanks for your help !

I’ve never seen a cross next to the flange. Something ain’t right. Are you sure the spoke lengths are correct? Take it apart and try again at least.

Looks like the hub wants 2x lacing. And the very idea by the designer to have flange grooves for j-bend spokes is funny, as in unnecessary.

Neat!
Try lacing it 2 cross. Even if your spokes are too long, just mock it up with spokes in rim eyelets to see how the geometry works out.
It’s true that 24 spoke wheels are generally laced 2x, but I never knew why until your post. If you look at the geometry, a spoke in a 2x pattern has to reach way further around the hub to get to the same place on the rim. Combine that with a longer arc length at the rim between eyelets and your problem makes sense!
Theres probably some fancy trig you could do, or some wheel building models, to see what works out best, but you’re re-using spokes right now anyway so trial and error!
I’d be willing to bet the hub company just kept the same exit angle and changed the number of spoke holes to 24 from 32. That angle looks like something you would see on a 4x wheel, so again, trial and error is probably your best bet here.

I did similar with front wheel when I did it, and messed up crossing of spokes still, that’s supposed to add a little bit of flex to spokes I think but been fine for years.

It needs to be 2x

It looks like it was previously laced 2x which you should return to. But that requires different spokes.
