I had a pair of U90 dumbells that I bought years ago, and was very happy with them. I got used to the narrow opening at the top. Then I saw the "Knurled Grip Hndles - Pro series" and read that they fit the U90 series so I just bought them. I'm very pleased that I did, becaue they definitely transformed my U90 into a more serious dumbells. Highly recommended upgrade for the U90.
