Riedell Ninja Wheels - Agile Roller Skate Wheels - 4 Pack of 59mm x 38mm Wheel

When i received the box they were shipped in the plastic packaging for the wheels was split open. I had a tremendously difficult time getting my bearings into the wheels. I was extremely frustrated, and I initially wrote a very negative review. Then I came across the note on the packaging that says to use lubrication on the bearings and a bearing press to get them in. Initially I tried using a c-clamp and even a hammer to get a few in! (Hammer was obviously a bad idea, but I only slightly damaged one bearing.).. Anyway, I found the trick is to put a little WD40 on the outside of the bearing and inner hubs of the wheels and then you can push on different sides of the bearing until it goes all the way in. Some bearings were too difficult to go into one wheel so I used it in a different wheel without issue. Thankfully I was able to get them in and tried them out tonight! They were much grippier than my older wheels but I'm starting to get used to them!

Very nice wheels!!

Went from nylon hubs, to these.Gotta say, they make me feel more “connected” to the ground, grip well when they need to. transitions make me feel more solid, and they roll pretty fast. I find myself rolling faster than I intend to, which is good for me >:-)

Durable. Super-easy to clean. Bearing seats are precise, so no press was needed to install my Super-Reds bearings. Note: they are significantly lighter weight than the 90A (Red) wheels. Floor wax/poly-coating cleans off them easily.Bottom line-wish I started using them 10 years ago.

Sonar Ninja wheels roll so good, I got 2 sets of different hardness (floor types I skate on vary from concrete to wood). However, I would recommend to the company they perform more quality checks at the lathe because on this run, the inside hub diameter tapered out and I had to re-work it so my bearings would seat properly. That aside, I still give them 4/5 because they are great wheels.

They are smooth

Everything arrived after it had been shipped across the country Twice!The delivery box was ripped open. Almost like somebody had been going through it. To the point the postmaster wanted to sign it as damaged.The product overall looked as described. I am not disappointed with the product. More or less the delivery and the care of it.

I bought these to transition to aluminum and I wanted black wheels. Black wheels are hard to come by if they aren’t rythym wheels. I have skated on them for about six months or so and I broke them in nicely. What I do not like is the bearing fit issue. They do slide out easily when I clean my bearings but they don’t fit snug like the nylon. I felt they were really heavy on my feet ( I’m 127 lbs) extremely bumpy ride( I feel every imperfection on the floor) none of my other wheels do this. My feet would actually ache after a long session and I felt completely slowed down when I can roll with the best. I am an advanced skater so I don’t take my wheels lightly. Your bearings and wheels are everything in performance. I just took them off and put my old psycho wheels back on until my new wheels come in next week. They look super nice but they feel like riding around on bald tires. I would probably invest in another wheel if you want the agility of aluminum hubs because these are definitely not it unfortunately . I really wanted to love them but my feet said NO
