These are the right grade and appear to be of great quality, and the price per bearing in this assortment can't be beat.

Good value with what looks like a decent quality ball bearing

Good quality bearings and worked great for our purpose.

Set looks to have all the common sizes and are of great quality, and yes they are magnetic

I wanted the higher quality grade 25 and these worked great.

Well, what really is there to review, they are indeed bearings, they are indeed a good price, and it is a nice assortment.

this is a good assortment of ball-bearings and the price was low enough to warrant the purchase just to have on hand if needed

Good assortment, but I wish they added another 100 3/32" bearings to complete the set

Also please note that the assortment also included 10x 1/2" balls (nice!)

Fantastic assortment that fit in every space that I needed them too

There's not too much to say regarding the product except it's a great price and higher grades aren't necessary

Fast, free shipping, great product, what's not to like.

The sizes were accurate, and this assortment was a good value for what I needed.

Good value with what looks like a decent quality ball bearing

I now always have the right size ball bearings when fixing the bicycles.

Good, cheep, standard size for vintage bike build with plenty to spare.

when I disassembled the hubs for inspection and repacking, I noticed that some of the ball bearings were completely shot, this kit definitely provided the perfect size and plenty of them to do both wheels.

inside of the bag are individually marked and labeled baggies containing each size of ball bearings pre-sorted, high-quality, thank you very much.

The bearings are packaged into different bags so that finding the right size is a breeze

This product is a great deal, and the bearings are exactly what you should expect.

421 and 621 ring magnets to pair with these since I couldn’t find a better deal on Amazon

I was unsure of the size I needed and this deal was better than buying one size and being wrong

Great set of bearings and good to have if you accidentally lose a bearing.

This set was perfect to replenish my stock, although I'm not sure I will ever use the smallest sizes.

The price was quite reasonable and I like having a set of ball bearing sizes in my tool and supply room.

Perfect set of bearings for replacing bearings in front and rear hubs in older bicycle.

These are the right grade and appear to be of great quality, and the price per bearing in this assortment can't be beat.

Nice shiny top grade steel bearing balls neatly sorted, but the containers are not resealable.

There's not too much to say regarding the product except it's a great price and higher grades aren't necessary

If you want a truly superior grade of ball bearing you can order some grade 5 or 3 ceramic bearings to use in something like a Dura-Ace or a Campagnolo Record hub.

Great items for what I needed!

good item.

Good item needed it for my bmx bike hub would recommend a lot it came in 4 days

great item

this item is excellent and the support it's

Correct size, each size packaged separately, new condition

This is a very convenient package size with enough of each size to service several sets of components

The rusty, pitted bearings had scored the races but these revived the nearly 30 year old hubs.

If it helps anyone else, I have Bontrager Duster 29" wheels with a Shimano Free-Hub.

While cleaning and lubing my 15 year old bike's front hub I discovered that one of the ball bearings had failed (see photo).

Repacking your hubs and BB (and cleaning/lubing your chain) is the best way to make ANY bike more efficient

I used these to replace the old bearings in a set of vintage bicycle hubs, packed with new grease, and now the hubs roll like a dream

Couple this with a great price and its hard to find a reason to be disappointed

I was overhauling my wheels and this assortment had what I needed and more for a great price.

Well, what really is there to review, they are indeed bearings, they are indeed a good price, and it is a nice assortment.

lot of bearings here for a cheap price

Wow, these are a great price for how many bearings you get

hard round balls ... of course they're good, they're bearings ....

Installed balls on rear axle of my bicycle, already worked well for 500 miles,and there's no backlash or play, I guess it will last few thousands miles

The balls are probably fine for other uses, but as paint Agitators in acrylic paints they cause rust.

Good value with what looks like a decent quality ball bearing

But the bicycle store sells only grade 300 stainless steel balls (not chrome steel), and a few extra would be handy

If there are not enough bearings on the old batch for an overhaul, throw them away.

These bearings are are great buy if you like to do most of the wrenching on your bicycle.

The higher the number as in grade 300 bearings, the lower the precision and quality

No excuse to not replace questionable bearings with assortment.

Replaced the bearings in my headset no problem
