I've got a frame that has a 1 1/8" to 1 1/4" tapered fork. The fork on it right now is pretty heavy and I've got another lighter carbon fork. I want to use the other straight 1 1/8" fork in the tapered headtube frame.
So is there a source for a bearing that will reduce the bottom bearing so I can use a 1 1/8" fork? I know trek did something like this for paris-roubaix.
