IWonder Mugen Black Ceramic Precision Skateboard Bearings 8 Pack Spacers & Washers Bundle Longboard Bearings Set fits Skateboard Inline & Roller Skates

Smooth and roll forever

I used these on 60mm skateboard wheels. They replaced bones reds and definitely felt faster for about the same price that I paid for the reds. Ivy been riding them for about a month and a half and so far so good. I’m happy with these.

Just get ceramics!

First, over the last 5 years I have tried several of the lower cost ceramic bearings. These are the best. These B3’s are amazing. I even later ordered the “steel built-in B2’s”. They also are amazing. Both are easily worth double the price.

The price and the quality

Are they ceramic? Are they not? They offer two different types of bearings but even the less expensive one states "ceramic" in the product description. I don't think these are ceramic. I get irritated by careless, poorly written and potentially inaccurate product descriptions. I don't care if there's a language barrier - hire someone who speaks English to write this stuff and take some care to ensure they descriptions are accurate.Rating bearings in terms of performance is pretty subjective. How the spin, what the rolling resistance is, how long they last, etc. are all highly dependent on use, conditions, and maintenance. If the value/quality of these bearings in commensurate with the price, they should perform well and last a long time. Maybe not Bones Swiss quality, but at half the price worth giving a try.

I got the B2 steel bearing version. They all spin fine and have removable shields for cleaning. They all have integrated bearing spacers. I plan to use them in my roller skates when I need replacement bearings but right now haven't installed any of them yet.

These are on the top of my list of best wheel bearings! I have never before had bearings with washers and spacers built into bearings like these. These have to be the strongest set up I've ever had on my inline skates because the spacers meet in the center of the rail like lasers etched them! These are high quality, precision bearings and I trust them 100% because I put them in two different 100mm wheels and the fit was excellent but the rolling smoothness was off the charts! Buy these Mugen bearings you wont be disappointed! They very well might be "Ultra Magical" like it says on the box!
