Like all Chrome products, the Chrome Knurled Welded Race Seatbag is built for life in the big city. As we all know, you have to be tough to survive in the big city. When it comes to this bag, tough is an understatement. Built from PU coated 600 denier polyester with welded seams, the Race Seatbag will stand up to anything you, Mother Nature, or the mean streets throw at it. The Knurled Welded Race Seatbag is designed to carry the bare necessities a small multi tool, a tube, a couple cartridges, keys, and a little emergency cash. Don't count on this seatbag to carry your lunch unless you're a very, very light eater. You can, however, count on it to get its contents to your destination completely unharmed, even in a full blown downpour.
