I just placed an order with Avid yesterday... hoping to get them by Friday so I can install them for this weekend.
At $1 a piece, I picked up 3 full sets for the front/rear hubs. They are cheaper than the replacement AE bearings. My hope is they are much more durable as well. I have heard good things about the Avid bearings and at this price, it isnt a big hit to the wallet if they dont hold up. I couldnt quite stomach the $100 price tage for Boca/Acer ceramics.
