The Erlen Saddle Bag Support provides a simplistic design, minimizing the chances of something going array. The Erlen sandwiches between your seat post guts with your seat rails by simply swapping the old bolts with the provided hardware. The provided hardware is one M8 (which will allow you to mount it into a NITTO S65) and two specialty M7 bolts designed to be used with a NITTO S83. Simply replace the bolts in your post with the one or two provided, reinstall your saddle with the Erlen, and you're good to go! No muss, no fuss, no cutting struts or scratching your frame up trying to clamp to your seat stays. With the Erlen properly installed load transfer goes directly into the seat post, which if you have a nice stout post like the NITTO S65 or S83 thats exactly what you want.
In terms of load you can go 15lbs or less if you're mostly on road or smoother surfaces. If you plan on hitting some ruff stuff like a ton of single track, then keep it lighter around 10lbs.
