Everything appears to be in very short supply at the moment. I've found a few websites that normally sell this hanger but all are out of stock. I was talking to a friend of mine today who owns one of the local bike shops and he was telling me he got an order to build a wheel for a customer who wanted it built with a Shimano 105 hub. He didn't have a 105 hub in stock so rang his supplier. He was given next August as the predicted delivery date. Honest. The reason he was given was that exporters are running short of shipping containers. What with Covid, Brexit and now shipping containers what will be next? A plague of locusts?
