When there’s ‘pro’ in the name, it suggests a little robustness. The two D-rings from Acebikes are designed and manufactured for the professionals, hence, an advanced use. Like a Goldwing or a bulky Harley Davidson.
The D-rings are to be installed in a trailer or cargo space, which is simplified by two predrilled square holes. When you’re not using them, you can simply lay them flat so that they are not in the way. All of the fixing material is delivered: two sturdy nuts (M10, 40mm) per ring with washers and flat-headed screws.
The D-rings are galvanised to prevent rust and corrosion and are made of high-quality steel. They can bear a lot more than the weight of a motorcycle; however, we should not neglect the pull forces on the back of a trailer or in a cargo space that easily exceed the net weight of the motorcycle. Anyway, these professional D-rings largely limit the risks of loading.
For the fans: the loading capacity is 2.250 daN, which generally corresponds to 2.250 kilogram-force.
