1 1/4" headset bearings?
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.

yeah, you're pretty much stuck. Personally, I'd measure your frame dimensions, look up the Park Tool - headset standards page to see if your 1-1/4" headtube section can be bored out to 36.8-36.9mm to accept the spacers operator linked to. Then bore out the 1-1/8" section to 33.8-33.9mm to fit standard 1-1/8" cups and use a standard 1-1/8" headset and fork.
