Vincita The Overnighter Bikepacking Saddle Bag Stabilizer - Anti-sway Bracket with 2 Bottle Cage Mounting Holes - Easy to Install to Saddle Rail

This worked for me, but made my balance feel a little unwieldy. I recommend this product for folks who have something else taking up the center of their bike frame. I could see folks who keep large locks or bike-packers with frame bags finding this orientation particularly useful. I like having this around so I can slap it on my saddle if I feel like adding some more bottles. I could see installing it on long, solo, rural rides where refilling bottles would be difficult.

The Vincita The Overnighter is a bikepacking saddle bag stabilizer designed to eliminate bikepacking seat bag sway, which can occur due to the weight of the saddle bag. The stabilizer has sidebars mounted to the saddle rail to minimize any bouncing under load, and its rectangular shape can secure bags better than single arms stabilizers. The stabilizer is easy to install to the saddle rail with an Allen Wrench M5, and installation instructions, nuts, and bolts are provided in the package. It is a universal design that can fit most bike packing saddle bags with widths up to 4.7 inches or 12 cm. In addition to preventing saddle bag sway, the stabilizer also has extra holes to fasten bottle cages to either side mount, making it ideal for backpackers since large frame bags might already occupy the bike frame. The arms are extra length to prevent the bottle cage from interfering with the rider. The stabilizer is made from sturdy alloy construction, making it stable and robust enough to endure all biking conditions. It is sand-blasted black in color, making it a minimal style that can match all bikes. However, it is not recommended to use this device on saddles with carbon rails.
