Element RC Enduro 1.9” The Ocho Beadlock Crawler Wheels (Black) (4)

If you need inexpensive, feather-light beadlocks, these will do. They grab the bead of a Traxxas Canyon Trail tire (not all beadlock brands do), so that's a bonus. One complaint would be the tiny button-head "wood-screw-thread" hardware included, to tie the rims together. A crude solution at best, and the 1.5mm hexes are easily stripped during assembly. Instead, I threaded the backing hub using an M3 tap to accept socket cap screws with 2.5mm hexes. Works much better. There's six per rim so you need 24. These rims are vented, but with a few wraps of electricians tape around the centre ring, they can be sealed up, if that's what you prefer. See them in action on YouTube under NaturallyRC.
