I bought a pair of these to carry two 3L dry bags on my front fork. They mount easily, but the retention straps can be a bit difficult to thread through the cage and be secured. Well made and a good value compared to metal cages. I like that they also include the climb mounts for an MTB fork.
This is a solid packing system that I've I've used on several trips. I use them with roll top dry bags to pack clothes, a sleeping bag, and other soft gear. These racks could probably fit my foam pad as well.
Installation was pretty easy. I watched a few YouTube videos first. With some trial and error got them attached to my carbon forks.
The racks haven't come loose since I installed them.
