Mounting system incompatible with the diameter handlebars strengthened to the gallows; forced "tinker" to adjust the brackets. Anchoring system of the bag too focused, resulting in a port of the bag too high on the handlebars; again forced yourself to try to lower the guard on the handlebars ... This product may have been designed by someone who never ridden a bike, and who has never hike! And of course, no manual !!!
