I usually buy another brand of bearings on desertcart simply because the quantity of reviews were higher. I decided to give these a shot and theyre awesome. Super smooth and even the look of them looks more premium. I wound up swapping the other bearings out for these and I can definitely tell the difference. Review: Simple upgrade to fishing reel knobs - Low cost improvement for replacing the bushings in Shimano type A knobs (bearing size 4x7x2.5). The ones I received was a little dry, but add a drop or two of decent reel oil (used Lucas reel oil) and you can feel the difference immediately from replacing the stock bushings. This is more of an improvement of the feel because if bushings not well lubricated or greased can have some resistance when turning the handle. Of if you had other reels with bearings in the knobs you will notice something's not as smooth in the knobs. This is a cheap way to improve the feel as 2 extra bearings in fishing reels can increase the price a noticeable amount. Good price for 10pack. ABEC5 is enough.. ABEC7 is obviously better but at time of purchase its cost was too high.
