Product Information

Full details

The XLAB Stealth Pocket 400XP is designed for triathletes and time trial cyclists who prioritize aerodynamics without sacrificing storage convenience. This top tube bag minimizes drag through a 5:1 airfoil ratio while providing secure, easy-access storage for nutrition essentials, though users should note that the storage capacity is optimized for smaller items like gels and salt tablets rather than bulkier gear.

Extended Product Information

FAQs

How many gels can I fit inside?

The main compartment is designed to hold up to 5 standard energy gels comfortably.

Does it fit all road bike frames?

The bag features long, adjustable Velcro straps that allow it to conform to a wide variety of top tube shapes and sizes.

Is the bag waterproof?

The material is designed to be weather-resistant to protect your nutrition, but it is not fully submersible or waterproof.

What is the benefit of the silver interior?

The high-visibility silver interior reflects more light, making it easier to see small items like salt tablets or labels inside the bag.

Will this bag scratch my bike frame?

The bag features a non-slip, soft-touch bottom, but it is recommended to keep the base clean of sand or road grit to prevent long-term surface scratching.

Troubleshooting

Bag shifts side-to-side during standing efforts

Ensure the non-slip base is clean and the three Velcro straps are pulled as tight as possible against the top tube.

Zipper feels stiff or difficult to pull

Clear any debris or salt buildup from the zipper teeth and ensure the contents are not overstuffed, which can put pressure on the track.

Velcro straps are too long for the frame

The straps are designed to be adjustable; once you have found the optimal position, you can carefully trim the excess length with sharp scissors.

Pros and Cons

Pros

  • Reduces aerodynamic drag with specialized airfoil shape
  • Easy-pull zipper design allows for quick mid-ride access
  • Stable mounting system prevents shifting during sprints
  • High-visibility interior helps you find gear faster

Cons

  • Limited storage capacity best suited for gels and tablets
  • Velcro straps may require trimming depending on frame size
  • Rigid inserts may limit the ability to stuff oversized items inside

Setup, Compatibility & Care

Installation is straightforward: place the non-slip bottom of the bag onto your top tube, ensuring the tapered front aligns with your stem. Use the three long Velcro straps to secure the bag; thread them through the base loops and pull firmly until the bag is centered and stable. To maintain the bag, hand wash it with mild soap and water, ensuring all grit is removed from the non-slip base to prevent frame abrasions. Always check that the zipper path is clear of debris to ensure smooth operation during your next ride.
