What bearings are these

[Sander23]

Had some cracking noise coming from the headset so I gave it a service.
Upper bearing was all rusted and little to no grease in it. I've packed it with some new grease for now.
But I'm still interested in what size these are in case I need to replace them.
Bearings have no info on them.

they often have the bearing number etched around the outside edge..
if not, check the manual for your bike, its probably got the bearing numbers in there.

I usually go to somewhere like this and put my sizes in: Bike Bearings and Mountain Bike Bearings - WychBearings.co.uk
Ive also bought a few cheapish bearing from ebay that have lasted really well (over a year) from here: Bicycle Headset Bearings Angular Contact *** Please Choose Size *** | eBay

I’d measure them by inside diameter X outside diameter x dearth then use the imperial measure across the top. And do a search on INA bearings. They look like standard headset bearings. But lookout for the bevel on the outside one them, they’re usually 35 or 45 degrees.

They are from a haibike fullnine 10. I've not found any documentation of it.

And no numbers found on the bearing edges

Verns are handy. The bearing is designated by external diameter/internal diameter/width then chamfer if applicable. Measure up, then put them in the site @dobbyhasfriends linked & you'll find what you need. Easy.

looks like a standard tapered headset, if the specs are the same

How can I know if they have a 35 or 45 degrees angle?
