Know before you buy
Yes, the pack is designed to accommodate a standard 1L water bottle. It serves as a secure, secondary bottle cage alternative for bikes with limited frame space.
The attachment system is designed to be secure, but like any strap-on accessory, grit can accumulate between the strap and the frame over time. We recommend cleaning the contact area before installation and using frame protection tape if you are concerned about cosmetic wear.
Yes. The pack features seam-welded construction and waterproof materials, meaning it will keep your gear dry even during heavy downpours or when riding through mud and puddles.
The pack utilizes a single-motion velcro attachment system specifically engineered for stability. When tightened correctly, it sits firmly against the downtube to prevent unwanted movement, even on technical gravel or off-road trails.
The hook-and-loop straps are highly adjustable, allowing the pack to fit a wide range of tube diameters. However, if your downtube is exceptionally wide or has an unusual aerodynamic shape, ensure there is enough clearance for the strap length before purchasing.
