Hi can anyone recommend headset bearings / maybe dust cap for a weight weenie build? The bike is a Wilier Zero.6. Also how many grams could be saved with light bearings?

Cane Creek AER? Extralite? Thanks in advance.

Fsa make alloy hybrid headset bearings called acb sl. You can drop 15-20gr compared to normal steel ones. 25usd a pop I think they were.

My bottom bearing measures 46.86 mm OD and 34 mm ID

That FSA bearing OD matches, but the inner diameter says 1 1/4 inch which is really 31.75 mm. Will this bearing work with my bike?

Not only the diameter needs to match but the chamfer angles too. 36/36 45/45 36/45 or 45/36.

I'm not the best to ask but I'd guess the inner diameter fits the three different sizes of fork crown diameter 1-1/2, 1-1/4 or 1-1/8. The upper id is always 1-1/8 but the bottom can be any of them. The od varies from frame to frame even though the fork may have the same dimensions.

Measure the existing bearing. Check for any writing on the bearing, see what the angles are.

I hope someone better versed in headset bearings can help you.

That would be risky.
