very grippy,would recomend them on a hard wood better than a concrete,i have a pair and they turn a dark yellow the more you ride them,if u are a speed skater and like smooth grippy,i recomend them,now i have a pair of anabolix chameleonII,and i recomend those for jamskaters (lowpriceskates should sell them again or origonal chameleons)

I am a stunt skater. Known for jumps, multiple tricks on one, two and four wheels on one skate or two...these wheels are the bomb when it comes to grip, durability, and all around speed. I would highly recommend them to anyone who likes to "show what they know" !!!! I've been using the backspin for well over a year now and they are still as awesome as the day I bought them...and believe me I ordered mine from a local rink..so I paid double!!!! But don't really care cause I would do it again for these jewels!!! If you have a skater that needs a nice gift these are the ones to give. They'll love them as much as I do. ♫♫♫♫♫♫♫♫ Jamm Skatin SpinMan ♫♫♫♫♫♫♫♫ "knowin and showin all around the country"

I am the First Soldier in the U.S ARMY Soldier Show History,to Roller Skate in the 26 years of the Show.I used the BackSpin Lite mix Wheels in 120 Performance thru 60 Military Installations across the USA and Overseas (Hawaii and Korea).When I finally returned to Roller skating on the Hardwood Floor,the center Hub cracked in the Front and back of my wheel.This Wheel has a history of Breakage,so I would not use these wheels due to this major Defect.Uncle Jamm,President of the Augusta Georgaia Jamskaters/2009 U.S ARMY Soldier Show Roller Skater performer.

Very smooth and VERY "grippy". I would recommend them!
