Quick Summary
The Topeak BackLoader Wishbone is a rear bikepacking bag stabiliser for Topeak BackLoader rear bags. It mounts to the saddle rail and is described as an anti-sway design that helps keep the bag rigid. The stated width limit is under 18 cm, so the bag size matters when checking fit.
It also adds two bottle cage mounting bosses, so the same unit supports extra bottle cage mounting points as part of the rear setup.
