I have these wheels on my current build. I love them. they grip on the floor, so smooth, and last a long time. I am a DJ at a roller rink and i skate 4-6 times a week, they have proven my test of time. Strongly recommend these wheels. If you are going to purchase these wheels get them in a darker color becasue the light ones get black and can get unsightly. Otherwise great wheel. Quality product

I have had these wheels for about 4 months and they were very smooth at first. Its hard to know how slick or grippy your wheels will be because there is not a numbered chart. I was looking for some extra grip so I got blue ones.. They are still slick.. They still role ok, but they have what my teammates call "hampster squeal"! If it werent for the squeal these would be pretty decent wheels but I get tired of eveyone asking.. Is that you???

These wheels are sick!! Out of all the wheels I ever bought these last the longest. They're fast,flashy and easy to keep clean!!!

I bouhgt the V-Drives and Qube ceramic bearing. WOW! what a diffrens it made. The smoothness and speed is nothing like Ive felt before. Im kinda a big guy at 6.5 and 240lbs so I went for the Green ones. They was a little slick at first but after 5 hours on them you could feel them sticking more and more.Cant wait to get them on the floor again to see how grippy they get.

Wheels were great the first time on but started squeaking after about 6 hours and then a small piece broke off from outer edge. Just 1 faulty set out of 1000's because Sure-Grip International stepped up and replaced the wheels at no charge and the new ones are flawless with 40 hours of rink time. Great company that stands behind there products, will continue to use always.
