Bungie
FrostBack #2 - IBA # 44620
I've used dyna beads a bunch of times with no complaints. Seem to work. But the interesting bit is what you see AFTER you've dismounted your worn out tire.
The beads are embedded in the soft inner liner and none of the beads are free to roll and provide 'balancing'. Maybe because they've taken a set their is no need for additional balancing. Or, maybe I ride to fast. But it would seem to me that some re-arrangement of the beads over the life of the tire would be required. Even more concerning is the roads up here are ROUGH, and with the constant pounding the tires take it would dislodge the beads with some randomness. It just doesn't appear to be the case though.
The seat of the pants says they work. The physical evidence suggests beyond the first few rides, they don't move at all.
shrug.
Pays yer money, takes yer chances
