This is a great upgrade for your bike! Easy to install, cleaner, looks good and performs even better. I have currently put on about 500 miles since installation and the performance is awesome. Tight smooth steering. Highly recommend.

After trying to use replacement ball bearings similar to what came with the bike, the forks didn’t sit correctly. I was getting super frustrated and kept removing everything and trying all over again thinking I was missing parts. I finally bought these bearings which are sealed. After I installed everything that came in the package, it fit like a glove. There was no more play in the bottom near the crown race. Just buy them, you won’t regret it. This would have saved me hours of adjustment and heartache.

This is a complete Headset with all the bearings and cup and seals in the kit. Easy to install and the seal bearings seem to be of great quality and materials. Will buy it again if I ever need another set.

The opened package version I purchased was missing one part, I was able to install the head bearing set without that part, however, it looks like people are still stealing items from packages and then returning them to Amazon. Overall the cups fit nicely and did not take any unnecessary effort to install. The bearings spin smoothly and are a nice upgrade to the bike. The red anodized cups and parts match the color of the anodized parts that were originally installed on the bike which is real nice.

Used to replace a Trek Marlin 5 stock caged bearing headset. New headset measured 44-44mm 1 1/8" exactly as ordered. Great price and smooth operation.

I needed a new headset for my AMYET S8 e-bike, and this was suggested from Amazon. Went on super easy, and it included everything I needed, and some extra parts for the install. Bearings are super smooth, and I have had zero problems since I installed about a month and a half ago. Would highly recommend this headset.

Good set of bearings and seals. I got a new bucklos fork for my 20x4 ebike and I spent a day trying to remove and install the bottom bearing race from the old fork to the new. I got the race off but it would not go on the new stem. The bucklos set has a split in the races so it can expand an extra millimeter or so. It fit like a glove and the bearings are very good quality.
