Good fit, and smooth.
This headset fit where it needed to, looks ok, works good. It’s nice and smooth. One thing I noticed was oil/grease on the bearings. Hopefully that’s residue from the manufacturing process and not from the bearings themselves since they are sealed, in the long run that could be a problem. But I inspected the bearings and didn’t notice any holes or punctures on the seals. I’m not a fan of branding/writing on these type of things unless it’s a super known brand but these look ok and they work. The set is complete so I don’t have to look for separate parts which is always convenient.

Smooth Headset Bearings
I don’t know why this is listed as Kodrily, the box and parts clearly say they’re Ztto brand. Regardless, this headset kit comes with everything you need including an adapter for different forks. I’m not crazy about the design or the brass colored top cap screw, but the bearings feel nice and I can just use my other hardware. Great kit to revive an older bike in need of a headset replacement.

Perfect for my new bike build
It doesn’t have the brand recognition of a Cane Creek, Wolftooth, or FSA, but at a fraction of the price, who cares? Works perfectly and would not hesitate to purchase again.

Great option for the price!
Replaced the headset on a Niner BSB. Fit perfectly and seems to be well-built, especially for the price.
