Please note that the video shows adhesive velcro on the top tube. this is *NOT* needed and is not how the bag attaches. it attaches by the velcro straps wrapping around the frame. the adhesive velcro is just there to prevent cosmetic buffing of the frame (I'm super anal-retentive) 3M clear tape works well too.
