Know before you buy
Yes, the pack is specifically designed for frames without accessory mounts. It uses a secure hook-and-loop strap system that mounts directly to the downtube, making it compatible with most frame geometries.
It is designed to accommodate a 710ml water bottle comfortably. The pack functions as a bottle holder, and its compressible design ensures the bottle stays snug and secure even on rough terrain.
The pack features a seam-welded construction, which makes it fully waterproof. It is designed to keep your contents dry even during heavy rain or when riding through wet conditions.
While it is low-profile, clearance depends on your specific bike geometry and tire size. It is best suited for bikes with enough space between the downtube and the front tire to prevent rubbing.
The pack uses a single-motion velcro attachment system combined with a stability strap. This setup is engineered to minimize sway and movement, keeping the bag firmly in place on gravel or bumpy trails.
