Using your EXP - R Series Bag Bundle is easy. First, find the right spots on your gravel bike to mount the bags. The Campion Frame Bag fits nicely in the bike frame, the Fireweed Handlebar Bag attaches to the handlebars, and the small Trillium Top Tube Bag can be placed on the top tube. All the necessary mounting straps and hardware are included, so you don't have to worry about finding extra parts. When packing, put heavier items closer to the center of the bike for better balance. As for maintenance, keep the bags clean by wiping them with a damp cloth after a ride. Avoid using harsh chemicals as they can damage the 1000D Cordura nylon material. Store the bags in a dry place when not in use to prevent mold and mildew. And remember, these bags aren't waterproof, so if it's going to rain, use a waterproof cover to protect your gear.
