1-1/8" Heavy Duty Headset Top Cap Bearings, 34mm / 44mm / 55mm Diameter Threadless Stem Tapered Sealed BMX Bearing Nuts for Mountain MTB Bike

It fit my KHS Alite 150 bike perfectly. I wasn't sure that it would fit but I decided that I could simply return the item if it didn't work out. So I felt lucky that it was a good match up to the original headset. In installing the new headset, I just had to be sure to install the complete headset including the race at the bottom, the dust seal, the bearings and the new bearing races/cups. The old cups were pressed in and had to be knocked out and the new cups had to be pressed in carefully. I assembled it all and took the bike for a test ride to make sure that the steering wasn't too loose or too tight. I thought I'd gotten it just right, but after the first 15 mile ride, I had to tighten it up again once all the parts had settled into their places. Now, it's nice and smooth to ride.

Good quality

Zero instructions and an oddly specific headset. I am not very mechanically inclined so it took me a while and I ended up using a crown race from a different headset… I guess that’s my fault though. It fits pretty well, no complaints there. Not super expensive and is pre-greased. Looks alright although the split plastic spacer feels kind of cheap.

Worked just like I was hoping

everything was there no problem with fit

Fit and work perfectly. Great price also.

The product description states that this headset is for a tapered stem. I ordered the 44 mm set, but both bearings are for 32 mm, even though the package is labeled 44 mm.

I like the price and the description was accurate for the parts that I needed. Made my 20 year old mtb steer like new again. I also need the star nut which was included with the bearings and it fit perfectly. Worked great. Thanks very much.
