The Hold Fast Frame Bag is our number one solution for smart, inconspicuous storage on your bike. The main compartment is accessed via a drive side water-resistant zipper. A smaller zipper pocket on the non-drive of the bag is perfect for a snack or cell phone. To accommodate a variety of frames, there are webbing daisy chains on the top panel for flexible attachment points and extra long fixed Velcro straps intended to be cut-to-fit to your needs. On the top of the bag we added an exit port for a hydration hose or power cable, and along the underside of the bag there is a webbing daisy chain that runs the length of the bag for additional lash points for items like a pump, tent poles.

Find our sizing guide under the “Specs” tab to ensure the best possible fit with your frame.

The Hold Fast Half Frame Bag made in Surabaya, Indonesia out of Challenge ECOPAK 100% recycled polyester. This pack contains roughly 5-7 plastic bottles rescued from ocean beaches.

Fits my bike frame prefectly. The pockets are positioned for easy access when I’m on the bike. It’s a great design.

2 years and rolling with my hold fast half frame bag

I purchased this bag with the idea that it would help me have a good storage solution for my gravel bike, and it has really come through. Easy to get it on the bike and secure. Love the quick access pocket. For my daily commutes I keep my pump, tube and levers in it. I have a quick spot to ditch/store a rain coat/vest. For longer rides I can access the compartments as I pedal (safely of course, grin). Construction is super tough. Really enjoy this bag!

Five Star Half Frame Holdfast

Bought the Half Frame Bag in dark tan. It's IDEAL for the camp seat wands and seat, my bivy sack hoop, a ground tarp, a long ziploc bag of oatmeal w/dried fruit, the water filter, hose, and empty water bladder and my sun hat - everything that rolls up thin and long.

These are great bags. I have one on two of my bikes and love them.
