BOOM Box in-frame storage with low door separate from bottle mount
Comes with Fidlock bottle plate and tool mount eyelets

As is stock, it was provided with dual 29" wheels, with the 205mm x 60mm shock giving 150mm of rear wheel travel.

Improved shock mount
Flip-chip allows for mixed wheel setup

Might take some work to get the correct sizing
Seat clamp bolt could be recessed for weather protection
