Finally, a ball mount that doesn't feel flimsy. The threaded stud made installation a breeze on my existing setup with zero wobble.

Finally a ball mount that doesn't wobble under load; the threaded stud screwed in perfectly on my bike rack. The all-steel build gives me confidence it'll last years.
