Purchased this pulley set to replace and upgrade the pulleys on my Shimano R7000 rear derailleur which uses bushings in the pulleys instead of sealed bearings. Deciding to upgrade my RD-R7000 with these pulleys which are also used on the Ulttegra was still cheaper than buying the R8000 rear derailleur. I have used the R8000-RD (Ultegra) on my first bike and this pulley upgrade on the R7000-RD(105) for my other bike has definitely put it on par with the Ultegra at a lower cost.
Pulleys with bushings produce a certain amount of lateral float float which causes a minute hesitation during up and down shifting. These Ultegra pulleys produce no such float resulting in relatively crisper and smoother shifting unlike the ones that came with the derailleur.This was an important and necessary upgrade for me and I highly recommend this Ultegra pulley set as a replacement upgrade.
