Good looking and practical. The Schwalbe Tire Bag made out of real folding tires and truck tarp. The practical details: Main pocket is large enough for a document binder. Separate document compartment. Zippered small article pocket. Back strap secures the bag while riding. We have particularly strict quality assurance with folding tires. Tires that are too heavy, have run out defects, or are optically un round are immediately segregated, but no longer immediately scrapped, rather they are processed into useful Schwalbe Tire Bags. 17x 15x 2 34 L x H x W.
