Bearings measure 12mm not 1/2 inch. Everything is precisely machined and high quality
The seller is also very responsive. Everything about these wheels just IS what its supposed to be, numbers are exact. I just happen to have been sent a metric version by mistake but my issue was fixed quickly.
The package I received was packaged very welland there was no damage. Very well made product no tooling marks or any marks for that matter. Very impressed with the quality
