Check the sizing carefully as there are multiple sizes of this for different bikes. I did, and this fits perfectly. Its strong as any thru-axle and more importantly, I can attach my trailer to this propertly.

Exactly what I needed for my Giant Trance 2017 rear axel. Now i can pull my bike trailer with my 2 year old in it on my mountain bike for some lower hill climbing gears.
