1. Product Overview
The NEWBOLER 10L Large Capacity Bicycle Saddle Bag is designed for cyclists who need a streamlined way to carry equipment without the need for a rear rack. Made from lightweight, highly water-resistant, and reliable 900D polyester fiber, this bag can be quickly installed and disassembled, making it ideal for medium and long-distance cycling adventures.

2. Setup and Installation
The saddle bag features an upgraded saddle installation system with compression straps for secure attachment and reduced movement during rides. Follow these steps to install your bag:
- Position the bag under your bicycle saddle, ensuring the narrow end faces forward towards the seat post.
- Wrap the main strap around the seat post and secure it tightly using the buckle.
- Attach the two side straps to the saddle rails. Thread the straps through the buckles and pull firmly to secure the bag in place.
- Adjust all straps to ensure the bag is stable and does not interfere with your pedaling or the rear wheel. The three-point fixation system helps distribute weight and prevent swaying.

3. Operating Instructions
The NEWBOLER saddle bag offers versatile storage and easy access to your essentials:
- Capacity Adjustment: The bag features a roll-top closure system, allowing you to adjust its capacity from 3 to 10 liters based on your needs. Roll the top down multiple times for smaller loads and fewer times for larger loads, then secure with the buckles.
- External Storage: Utilize the elastic cords on the top of the bag to secure additional items like a jacket, water bottle, or helmet for quick access.
- Side Pocket: A zippered side pocket provides convenient storage for smaller items such as keys, wallet, or phone.

4. Maintenance
To ensure the longevity and performance of your NEWBOLER saddle bag, follow these maintenance guidelines:
- Cleaning: Wipe the bag with a damp cloth and mild soap to remove dirt and grime. Avoid harsh chemicals or abrasive cleaners. Allow to air dry completely before storage.
- Water Resistance: The bag is made from water-resistant material and is designed to withstand ordinary drizzle. However, it is not 100% waterproof. Do not directly immerse the bag in water. For heavy rain, consider using an additional waterproof cover for sensitive items.
- Storage: When not in use, store the bag in a cool, dry place away from direct sunlight. Its foldable design allows for compact storage.

5. Troubleshooting
- Excessive Swaying or 'Pendulum Effect': If the bag sways excessively during your ride, ensure all straps (seat post and saddle rail straps) are tightened securely. Distribute the weight of your items evenly within the bag, placing heavier items closer to the saddle. The upgraded saddle installation system and compression straps are designed to minimize this effect.
- Difficulty Closing: If you are having trouble closing the roll-top, you may have exceeded the bag's maximum capacity. Remove some items and try again.
