Any ideas where I can get them?
First check exactly which A9 you're looking at, there have been many varieties over the years. Then actually take it apart because you can't be confident from external appearance. If you actually have angular contact cartridge bearings, read the part number etched on the outer race, or take detailed measurements and determine the equivalent part from the ACB page on the TH Industries web site. Google search by bearing designation or TH part number and discover that the only shop which has them in stock is in Singapore. Finally go to your bike shop and buy a Cane Creek 40
