Are Abec 7 speed bearings good?

Answer 1

I've never had a good set of abec 3's. They are fast for about a day and they're shot. I would highly recommend blowing the money on some Bones Swiss. They last around 5 times longer than the best abec 3's. Just stay away from water, mud, thick dirt, or anything that may gunk up your bearings.

Answer 2

I've heard from skate parks web site that most people think that abec are better with lower rating but higher ratings are usually better. It all really depends on the brand.
