stronglight a9 headset (1")
Proprietary, definitely not 30mm ID because that would be a 1-1/8" headset
I asked SJS and they assure me it's the correct bearing for 1" or 1 1/8".
Which it almost definitely isn't.
Oh well.
Think I'll get her to fit a cheapo one until we can measure the bearing and order it.

It's not a physical impossibility, but the 1" cups would look huge, like the bottom half of an FSA Pig
