Swift Industries Hold Fast Half Frame Bag


Waste not, want not is the rallying cry behind the Hold Fast Half Frame Bag. Pack smarter by making clever use of the inner triangle of your frame.

  • Finally! A practical home for awkwardly shaped essentials like your pump, your tent poles, or your hydration bladder. Running frame-mounted water bottles? Don’t fret: We took extra care to maintain clearance so you can easily slip your bottles in and out of their cages. The Hold Fast Half Frame bag will add functional capacity to your setup, whether it’s for your daily commute or an overnight adventure! 


    The Hold Fast Half Frame Bag is made from recycled polyester and contains roughly 5-7 recycled bottles rescued from polluted rivers.


    The space beneath your top tube has always been a coveted zone for convenient and spacious storage capacity, and with the Hold Fast Half Frame Bag, Swift Industries has at last entered the triangle! The roomy main compartment, accessed by a water resistant zipper, is a perfect home for long or oddly shaped items commonly used by cyclists — think pumps, locks, water bladders, etc.  On the non-drive side of the bag you will find a small zipper pocket with room to stow a wallet and snacks. There’s even more to the Hold Fast Half Frame Bag: on the underside we added an external daisy chain that runs the length of the bag to give  you the flexibility to add capacity or quickly lash on last-minute or mid-ride items to the bottom.

    In order to accommodate different frame sizes the Hold Fast Half Frame Bag comes in three sizes. Please, check the measurements of each size and measure the internal dimensions of your frame to get the bag that will fit best.
