3 cross. Simplest, best strength/weight, the way a wheel was meant to be. Radial the front if you wish and are using rim brakes. Other than 3-cross was very uncommon 'round here in '96.
All my wheels are 3cross, then the Zaskar will be the same.
950 XTR hubs, Ritchey Vintage Expert rims, DT stainless spokes. What tyre do You recommend for everyday use, road and off-road?
Foldable Schwalbe, ir IRC?
For mtb's, I think the stronger the better, so 3 cross all the way. Unless I get some cheap factory-built wheels, then I use them as they come. But replace with 3x when they die.
For a time trial bike, maybe radial front, but not a great deal in it, regarding aerodynamics I don't think.
I build all of my own,and my customers wheels, 3 cross. Strong and long lasting. My time trial bike is radial front and 3 cross drive side rear and radial non drive side,but I wouldn't build like that for anyone else as people tend not to avoid potholes etc.
Snowflake looks good though.
I did once use some factory built G.T wheels which had a radial front for dirt jumping and they survived a fairly long while but I am a smooth rider.
