What is a good "spoke cross" thing for BACK wheels? Im talking about Radial, 1X, 2X, 3X and 4X...
Which one is the best for mostly trails and a little park and pegless street (if what you ride matters)
The wheel is gona be a:
Shadow Cassette 36h (i dont think they make a 48h, if they do ill get it)
Odyssey Hazzard LT Rim Chrome
Spokes of any kind, maybe DT (if have the extra $$)

Ok thanks, oh and just for the note, i wasnt considering radial, i just put if to help people get an idea of what i was talking about...
i am going to do a 3X on a 36h rim with probably 2/1.8mm double butted spokes. i might do straight gauge...not sure yet

how many spokes a spoke would intersect going from the hub to rim

3x for 36h, 4x for 48h.
Crossing more spokes doesn't make your wheel stiffer, it just makes the angle at which the spoke pulls on the hub flange closer to tangent. Forces applied in that direction are less likely to rip your hub apart, but the wheel becomes heavier and slightly *less* stiff, which means you're more likely to bend rims. A radially spoked wheel is the stiffest and easiest to keept true, but your hubs will explode. So, there is a sweet spot, a point of balance between hub and rim longevity, and this hinges on how the hubs are *designed* to be pulled on.
The more crosses you have the flexier the wheel is and the freater the impact it can absorb, similar to butted spokes. If your 36h is big enough then it's probably worth going 4X, but lots of 36's aren't.
