To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzes reviews to verify trustworthiness.
Quality bearings - I ordered these as an upgrade when I ordered some hubs, that came with the usual cheap crap china bearings. I'd rather upgrade the bearings right up front then take a chance on being stuck beside the road because my crap oem china bearings disintegrated.
The best money can buy for the very heart of a wheel assembly. Made in USA. Far better the Czech or Chinese made bearings. Have been buying Timken bearings for 30 years. Just replace the China bearings in a Magic Tilt trailer shortly after purchase. Amazon is the lowest price.
