Product Information
Full details
The Topeak Fast Fuel TriBag - Large is an ideal solution for endurance cyclists, triathletes, and commuters who need immediate access to nutrition or small essentials while on the move. Its aerodynamic design keeps your items secure and organized without hindering your pedal stroke, though riders with extremely narrow top tubes may find it slightly wider than expected during out-of-the-saddle climbs.

FAQs
Will this bag fit my phone?
The 0.7L compartment is spacious enough for most modern smartphones, though you should check your specific device dimensions against the internal compartment size.
Is the bag waterproof?
The bag is water-resistant thanks to its 600 denier construction and TPU cover, but it is not fully submersible or waterproof.
Does this bag come with mounting bolts for the bosses?
Yes, it is designed to mount directly to standard top tube water bottle bosses.
Can I use this on a carbon frame?
Yes, but ensure the straps are tight to prevent the bag from rubbing against the carbon finish over time.
How do I prevent the bag from rattling?
The bag features built-in zipper docks to secure the pulls; ensure the zippers are fully seated in these docks when the bag is closed.
Troubleshooting
The bag shifts during out-of-the-saddle pedaling
Tighten the adjustable nylon straps further or ensure the direct-mount bolts are fully torqued.
Zippers are difficult to operate
Check the zipper dock for debris or grit from the road; clean with a soft brush and consider a dry silicone lubricant.
Pros and Cons
Pros
- Large 0.7L capacity holds more than standard nutrition bags
- Dual mounting options accommodate various frame styles
- Padded interior protects delicate electronics
- Highly durable 600 denier fabric construction
Cons
- May interfere with knees on very narrow top tube configurations
- Clear TPU top can create glare in direct sunlight
- Requires specific head tube and top tube diameter range for optimal fit
Setup, Compatibility & Care
For installation, ensure your bicycle meets the fitment requirements: a head tube diameter of 53-75mm and a top tube diameter of 38-52mm. If your bike has integrated water bottle bosses on the top tube, align the mounting holes and secure the bag with the provided hardware for a cleaner look. Otherwise, use the included adjustable nylon straps, ensuring they are pulled tight to prevent lateral movement. To clean, simply wipe the 600 denier polyester fabric with a damp cloth and mild soap; avoid harsh chemicals to protect the TPU top cover.
