2020 Optic headset bearings

[komdotkom]

I'm doing some work on a mates bike and it needs headset bearings. It's a 2020 Optic but I can't see a specific part number listed anywhere for it it. I assume it's just a generic bearing then?

The headset will have a brand on it somewhere (FSA maybe?) in which case you'll want to get the right bearing to suit the cups/crown race.
The tapers and sizes of bearings can vary from brand to brand and sometimes look close but be enough to give you a clunky headset.

Are there any markings on the bearing or seals?

The details should be etched/printed on the outer shell.

Generally this is how I would identify it but my friend isn't a maintenance guy and from why I can tell his bike washing technique goes like this.
1. Submerge entire bike in muddy water for 2hrs
2. Pressure wash with salt water
3. Don't clean the drive train just add more heavy grease, 500g should do it
4. Leave bike in the rain, do not drip dry

Subsequently the bearings are so corroded that any markings or etching cannot be read.
I'll take what's left of the bearings to a LBS and match it up.
Now onto the bottom bracket which sounds like a couple of bricks in a cement mixer

Below is the Norco small parts list, its very helpfully has everything required barring the head set !

Yes, that was the first place I looked but I can't understand why they wouldn't include it. I'm assuming all late model Norco's run the same bearing.

If he wasn't such a good bloke I'd agree with you, bike vandal for sure.
