Hope Hoops every time
all hub spares available next day from Hope dealers, and Hope in the UK give excellent backup for any warranty issues, plus multiple axle setups including QR, QR15, 20mm, 135 OLD QR, 135 OLD screw-in bolt and 142mm x 12mm syntace using affordable adapter kits
the Hoops use regular J-Bend spokes and brass nipples, meaning replacements are very easy to source (walk into any bike shop..) and cheap too
the Stans ZTR rims are excellent with great strength to weight ratio and easy installation of tubeless conversion systems, with secure bead lock on tubeless ready tires and good reliability in terms of tubeless security over time
rims are also readily available if you mangle a wheel in a crash!
