The Brooks Challenge Large Tool Bag is a saddle bag for fitment to the rear of a saddle bearing bag loops or over the handlebars. It features buckles located within the hold itself to ensure greater security while the strap that closes the unit encircles the bag's contents, preventing them from rattling during transit. The first Challenge was designed and patented in 1896. The Challenge Large has a lot in common with its distinguished predecessors, but now features triple the volume!
