Although my Spud Rollers wore like iron, I have stopped selling them. In fact, I have even stopped using them myself. I discovered the impact from the drive chain was causing the roller bolts to fracture the plastic chain guide. Therefore, I have removed the Spud Rollers from my chain guide. In fact, I haven't even replaced the chain guide slider. I have left the bottom of the chain guide open. Since I am not taxing the bike's suspension anywhere near its limits, I haven't had any problems result from opening the bottom of the chain guide.
Therefore, my experiment with chain rollers is complete. If I ever decide to once again enclose the bottom of the chain guide, I will revert back to the stock, chain guide slider.
I have sent a personal message to this forum's moderator asking him to close this thread. I wish to thank everyone who purchased my Spud Rollers, and I wish you all ride nothing but happy trails.
