I've had these in my artistic skates for about 4 years, and they're still FAST and smooth. Not sure if I need new ones for the carreras I just ordered, or if I can just steal them from the artistic skate. Heck, at 4 years old, they're still holding up great.

i switched these bearings out with my old one these are the best bearings ever they are cheap an fast....though they tind to bend if you jam skate....so i would recommend if you jam skate get qube juice bearing but as far for speed these are the way to go

the reason you guys aint feeling a differnce in your speed is cause you anit got them brock all the way in

I went from the abec 7 to these China(bones)reds and its a world of difference..for 30 bucks u can't beat it..these are a lot smoother and roll a lot longer...cruising or rolling is effortless with these...although I will be trying the bones swiss simply because there's a Tru roller at my rink that have the swiss bones and let me tell yawl, he looks to be floating on air at very high speeds......so I give these reds 5 stars....

my dad works at the bones factory in oklahoma and i compared them to bone ceramic and they spin the same no lie worth the price oyu should get them
