I need a bottom bearing for the following headset:

Acros Azx-212-co Azx-212-co, Sealed Bearings, Zs44/28.6 – Zs56/40

Does anyone know what that means and can point me in the right direction?

Thanks

My advice would be to not replace it with another Acros. The seals are terrible.

Indeed, hence my question!

Try Balfa.co.uk for all things Acros 👍

Acros are awful

Have a look at Cane Creek

I’ll second this ^^^^^
The Acros headset that came on my last bike (YT Jeffsy) had the bearings bonded into the cups so the whole headset had to be replaced when the bearings were shot, which was around 4 months from new

Getting shut of the across headset in my canyon was one of my better choices.

Bit more expense up front but getting rid of those overly tight composite headset cups made a lot of sense!
