The Wishbone is an innovative U shaped metal bracket that bolts to one of the seat tube bottle bolts and supports the side of the framebag from the outside. It acts as an exoskeleton for the framebag, positioned low where the crank arm rotates. Its purpose is to allow for a wider framebag (more volume!) or for storing water bladders low in your framebag while preventing the bag from ballooning out and rubbing the crank.

The most common situation that we've seen cranks rubbing the framebag panel is when triangular framebags are carrying large water bladders at the bottom of the framebag. The bladders are heavy enough they force the sides of the framebag outwards towards the crank.

Typically framebags avoid this problem by using narrow spines, which limit the overall volume of the framebag, or they use dividers that connect the driveside and non drive side fabric panels together in the middle of the framebag. Dividers are great, but the space they kill inside the bag can be frustrating. The Wishbone allows you to leave the bag wide open on the inside and while still protecting the area right next to your crank arm.

    Perfect for my DIY frame bag. A little pricey but worth it. All bike related gear is pricey.
