We like a saddle bag that isn't too big or too small, easily allowing us to fit our necessary tools and spare tubes if anything goes wrong while out on the road. The Road . 75L Saddle Bag falls right in that happy medium of sizes and is designed to fit snugly under the saddle with a tapered aerodynamic shape. The Fast-Fix strap system attaches the bag to the saddle with an elastic strap and a nylon hook, ensuring a secure fit that you'll almost never have to adjust. If you do need to move the saddle bag around, however, the Nifco nylon saddle rail buckle is designed with a quick-release to make removing or attaching the bag easy and stress-free.
