Atom Poison Savant Wheels with Bionic Bearings 8mm Full Set of 8 - Purple

After more than twelve years playing roller derby I've learned a few things about wheels. I like a firm wheel with mid range grip. Without a specific durometer on these I wasn't sure what to expect. I'd ordered eight purple wheels with bearings and eight in blue without. My daughter wanted to mix them up so I've got them alternating on my skates.I like that these have very little mushiness to them, like outdoor wheels. They're used in a polished concrete that is currently pretty slick. My 97a wheels had no grip at all, while the outdoor 84a wheels gripped okay but felt like I was skating in peanut butter. They feel like an 88a-91a to me, but they felt different on a wood floor that isn't as slick as the concrete. In a good way, it's like they adapt a little bit. I doubt I'll use them on an outdoor hockey rink that's nearby, and definitely not on asphalt. The wheel itself is thin and I think those surfaces would eat through them easily.These are also lightweight. They're the lightest wheels I think I've ever used. But the best part is that they still have the firm feel of my aluminum hubs, and it doesn't feel like the spokes are wimpy.I like the bearings that came with the purple wheels enough to be looking for another set. They sealed out the dust and heavy pollen that coats everything at the moment much better than my other bearings. I didn't notice any excess grease either.For reference I'm not inclined to do much jumping, I generally block, and weigh 140-150. I do a lot of plows and loved that these were easy to control with small changes in pressure. They didn't catch the floor unexpectedly but also gripped with ease. Still need some more time in them to not have to think about them but I don't see these earning less stars.

Good quality. Roller derby qualified. Only issues were that when received my Packaging was messed up and bearings tube busted. Other than that, nice and smooth.

Purrfect wheels. Great on local wood indoor rink.

I am trying to contact amazon and/or this company. I did not receive bionic bearings with my 8 wheels that I paid for. The wheels look great but I can’t attach without the bearings I paid extra for.
