Question: How good are these bearings? Do they spin well and are they fast?
Document: First off, these bearings are by far the best i have ridden, i longboard, and for these bearings to work this well makes me want to never use bones reds again! They spin forever and have come pre lubricated. They are double shielded so dirt cannot, and will not get in!!! Stop reading this review and add to your cart!!!! if you cant afford these, try some independant 5's. they spin FOREVER AND EVERR!!!! ORDER NOW! !
These bearings are amazing. I ordered them twice and their super fast. The third time I ordered them I had 4 slow ones in the package!! Thats unacceptable and I cant get in contact with the seller. Sad these are really great bearings if you get good ones.
Picked it up for about $15. Comes with four spacers and sticker. Just put them on today, and the bearings roll fast and long. They seem to be a true abec-7 rated bearing. We'll see how they hold up over time, which will determing how good of a value they are. But so far, so good. I'll update if necessary.
I was initially quite disappointed that it did not spin that long as seen in U-tube. It stops in about 10 to 15 seconds. Anyway I replaced my 3 scooters with this product and brought my family to the park to test it out. It definitely runs smooth and goes a long way. In fact I was initially a bit scared of the change in speed compared to the original factory bearings - too fast to stop!.
the bearings are smooth and well lubricated and very well package. im very pleased with my shake junts best bearings for the price!!!! !
Awesome bearings, just replaced my reds with these and I know they're new bearings but performance is twice as good as my reds right out of the package, Im sure these bearings will last just as long as bones reds considering I clean them regularly.
These came oiled, in a blinged out gold-looking race, with a "Getcha Roll on" sticker and spacers. These bearings kill it. Well worth the price, China Bones be damned.
