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. Review: Perfect for the price - Worked perfectly for what I needed. Seem solid looks good. Good price. ## Features - Material: Forged machined steel cups and oversized 1/4 inch bearings in the lower cup, this headset will not let you downk. - 1-1/8" Threadless headset Completed with star nut and bolt. - Specification: Use for 1-1/8" (28.6mm) Straight Fork Tube, Headtube ID.: 44mm, Crown Race: 30mm - Durable, smooth, lightweight and durable headset, is suitable for MTB, Road Bike. - If not satisfied with the bike headset, please apply for unconditional return and refund within 180 days. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08P4KWZBG | | Bearing Number | 2 | | Bearing Type | Ball Bearing | | Best Sellers Rank | #47,057 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #18 in Bike Headset Spacers | | Brand | BQPOLING | | Brand Name | BQPOLING | | Compatible Lubricant | Grease | | Customer Reviews | 4.2 out of 5 stars 228 Reviews | | Item Dimensions | 2 x 2 x 1.8 inches | | Item Weight | 100 g | | Item dimensions L x W x H | 2 x 2 x 1.8 inches | | Manufacturer | BQSHOP | | Material | Alloy Steel | | Material Type | Alloy Steel | | Model | BQSHOP | | Number of Items | 1 | | Outside Diameter | 44 millimeters | | Part Number | BQSHOP | | Specification Met | ABEC 1 | | UPC | 738629379374 | | Unit Count | 1 Count | ## Product Details - **Bearing Number:** 2 - **Brand:** BQPOLING - **Item Weight:** 100 Grams - **Item dimensions L x W x H:** 2 x 2 x 1.8 inches - **Material:** Alloy Steel ## Images ![1-1/8" Heavy Duty Headset Top Cap Bearings, 34mm / 44mm / 55mm Diameter Threadless Stem Tapered Sealed BMX Bearing Nuts for Mountain MTB Bike - Image 1](https://m.media-amazon.com/images/I/518EUJyP6rL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ BQSHOP Headset Review *by S***R on April 4, 2022* It fit my KHS Alite 150 bike perfectly.
