The Brooks Saddle Challenge Tool Bag is a tool bag that neatly fits into the rear of a saddle. The Challenge has a long history dating back to 1896, when it was first designed and patented. The buckles have a twinfold purpose, securing the flap of the tool bag shut while keeping the bag locked securely into the saddle’s bag loops. The strap that encircles the tools inside the tool bag makes sure the tools don’t move around and rattle inside the bag while you’re riding. It’s still made in England from vegetable tanned leather, and comes in a range of colors. Your choices include everything from cool blue to jet black and the traditional brown leather colored tool bags.
