Started last May to get a Grant 3021 or 3001 quick release hub. Ordered from Summit and canceled it in Sept. because of non-stop backorders. Still not available. Now they say in January. Don't think so. Have been calling around and some suppliers are saying Grant is making them in China, not in the USA. Production issues over there. Suppliers having trouble getting Grant products. Not sure yet what I will wind up with, but will try and avoid Grant if possible. Any of you folks had recent experience with them? I can't believe I am the only one.
