Worked great on my Fulcrum Racing wheels
after ordering the wrong bearing several times, i finally figure out I needed an 18mm inner bore, and the original bearings were not marked correctly. These fit my Fulcrum Racing wheels perfectly.

MTB Front Bearings
I bought these to replace my front sealed bearings in my MTB wheel. I had no issues with the size and they were exactly what I was expecting. My only concern with these was that they spun rather quickly, as if they didn't have enough grease. I took off the seals and shot more MTB wheel grease into them, put the seals back on, and the bearings felt much better. For the price, I can't complain and I'm sure these will last a decent amount of time.

Poor longevity, poor quality
They feel fine at first, but after just a couple of months, the bearings were in worse condition than the 2 year old bearings they replaced. Just spinning the wheel in the stand would cause noticeable vibration through the bike frame. Not recommended. Buy from a reputable brand and retailer instead.

High quality sealed bearings
These appear to be high quality sealed bearings. The front wheel bearings on my bike were starting to get noisy so I replaced them. Now they’re running smooth as silk and completely silent.

Good Bearings
These seem like good quality but time will tell. Install went well!

Poor quality
These bearings were worn out after two rides on the gravel bike - one training ride and a 110 mile race. They were trashed/grinding and worse than the old bearings that were over a year old.
