Sorry, miscommunication - munted over here means broken or damaged. I thought you must have done major damage to your headset & was curious to see the result.

There are no headset cups...the Rails have integrated headsets meaning the bearings drop straight into the frame...

Here are the bearing sizes, if you want them, I believe the Cane Creek Hellbender series will fit if you're after something of higer quality, but if you slap plenty of marine grease around the oem bearings last quite well

They must have changed the top bearing since our ones were built as the one pictured is the same the new one I got. The one it replaced was similar to the bottom bearing with no seal on the bottomHere are the bearing sizes, if you want them, I believe the Cane Creek Hellbender series will fit if you're after something of higer quality, but if you slap plenty of marine grease around the oem bearings last quite well

Is your new bearing FSA or something else?

Not sure. It does look like the FSA bearing you posted.
