Giant H2Pro Frame Bag

The H2Pro uses a flexible strap attachment system, making it compatible with most standard bike frames. Because frame geometry varies significantly, we recommend measuring your bike's main triangle to ensure the bag's dimensions align with your specific frame size.

The bag is constructed from a proprietary three-layer waterproof fabric and features a weather-resistant zipper designed to keep your gear dry during wet rides. While it provides excellent protection against rain and trail spray, it is not designed to be fully submerged.

Yes, the hidden port is designed for versatility. You can route either a hydration hose or charging cables through it, though using it for both simultaneously may be tight depending on the thickness of your cables and hose.

The strap-based mounting system is designed to secure the bag firmly within the frame triangle. When tightened correctly, it maintains a stable center of gravity, though you should ensure the straps are snug against the frame tubes to prevent any movement on rougher trails.

The bag includes an integrated internal storage pocket specifically designed to keep smaller essentials like multi-tools, keys, or energy gels separated from your bulkier gear. This prevents items from shifting around and makes them easier to locate quickly.
