Product Information
Full details
The Topeak Backloader 15L is designed for long-distance bikepackers and adventure cyclists who require a high-capacity storage solution without the need for a rear rack. It offers a streamlined, stable way to carry bulky items like sleeping bags or extra clothing, though it is best suited for bikes with sufficient tire clearance to prevent the bag from rubbing against the rear wheel.

FAQs
Does this bag fit all bike types?
It is compatible with most bikes, but you must ensure you have at least 3-4 inches of clearance between your saddle and rear tire.
Is the Topeak Backloader completely waterproof?
The pack includes a waterproof inner bag designed to keep contents dry, while the outer nylon shell is water-resistant.
Can I use this with a carbon seatpost?
Yes, but ensure you do not overtighten the straps to avoid damaging the carbon surface.
How much weight can the 15L bag carry?
The bag is designed for lightweight bikepacking gear; avoid overloading it with heavy metal tools or dense items that exceed a reasonable weight for a seat-mounted bag.
Is a tool required to mount it?
No, the bag uses a secure hook-and-loop strap system designed for tool-free installation.
Troubleshooting
Bag sways side to side while riding
Tighten the compression straps and ensure the seatpost attachment is as snug as possible.
Bag touches the rear tire
Repack the bag to shift weight higher or toward the seatpost; ensure the bag is rolled tightly to reduce its downward reach.
Difficulty closing the roll-top
Use the air release valve to vent trapped air, allowing the bag to compress further before folding the top.
Pros and Cons
Pros
- Eliminates the need for a heavy rear rack
- Excellent stability reduces the pendulum effect
- Dual-layer waterproof protection
- Compressible design for a low-profile fit
- Easy tool-free installation and removal
Cons
- Requires significant tire clearance to prevent rubbing
- Can be difficult to load evenly when fully packed
- Heavier loads may require precise strap tensioning
Setup, Compatibility & Care
To install, open the hook-and-loop straps and loop them through your saddle rails, then secure the larger strap firmly around the seatpost. Ensure all straps are tightened significantly to prevent movement. Before heading out, check that the bag does not contact the rear tire when the bike is fully loaded; if it does, you may need a seatpost extension or a different packing configuration. To clean, wipe the nylon exterior with a damp cloth and mild soap; do not machine wash. Ensure the inner dry bag is clean and free of debris to maintain its waterproof seal. Always dry the pack completely before storing it for long periods to prevent mildew inside the waterproof liner.
