Can't help with the beadlock but my buddy has them and destroyed the rear twice already. Once at Whistler (understandable) and once on a trail with small drops (3 ft). He's no hack, the rims are just garbage if you ask me; do a search, not a lot of love for those rims so he's not the only one. Practically gave him a set of Singletracks just so he can ride.
"There's two shuttles, one to the top and one to the hospital" I LOVE this place!!!
