The last skateboard I ordered arrived with Enuff ABEC 5 bearings, as opposed to the ABEC 7 bearings on the listing.
The ABEC 5 bearings were adequate and done a reasonable job with regards to speed and distance, however the ABEC 9 bearings were a huge step backwards.
Although they are quiet, the performance was highly disappointing and I personally feel that they were a waste of money.
