Seat bags are great. Allen wrenches, a multi tool, a tube, and some tire levers right there under your seat when you need them. The problem that we've always found with seat bags, however, is the size. Manufacturers seem to get shy when it comes to making a seat bag that can actually carry a useful amount of gear. We'd like to carry two tubes, a multi tool, a snack, our tire levers, a chain breaker, a couple CO2 cartridges, and an ultralight rain jacket. It looks like we'll need to ditch the wimpy seat bag and reach for the Chrome Knurled Welded Gravel Seatbag. The Knurled Welded Gravel Seatbag carries all of that gear and more. The unique cinch system allows your load to extend well past the back of your saddle, so there's room to spare. You don't have to worry about the weather, either. The PU coated 600 denier polyester panels are held together with welded seams completely waterproof and ready for anything.
