Custom Dyneema DCF Framebag


This fabric is a 2-layer laminate; one side is Dyneema (aka cuben fiber), the other is polyester. The polyester adds strength for stitching and abrasion resistance. Visit the Framebag Features page for more information on your build options.


Our Dyneema Hybrid framebags are the ultimate choice for ultra-light gear. It has the highest tear and tensile strength of any fabric for its weight and thickness. The 2.92 and 5.0 Dyneema are a hybrid material, made with a 50 denier matte polyester face mated to a shiny Dyneema face. The 50 denier polyester side is more abrasion resistant then the dyneema side and is used for the inside of your framebag (to better resist wear from the contents of your bag - see the Rockgeist Go Bag to help prevent abrasion holes). The 5.0 Cuben Fiber uses an even stronger, 2.15  oz/yd 2 dyneema mated to an 150D matte polyester side. If you would like the matte polyester side facing out instead of the shiny cuben fiber facing out, please let us know in the comment field on the billing page.

Base features:

  • Durable #10 YKK zipper, black
  • Variable velcro attachment to the top tube near your stem. This allows compatibility with your choice of top tube bag, including the Rockgeist Cache bag.
  • If a horizontal divider is not chosen, large framebags at risk for leg rub will come with a vertical divider.
  • Hydration/electronic access
  • Drain port


PhotoFit™ Template Creation: A strategic photo of your bike is used to build all Rockgeist framebags. PhotoFit™ offers several advantages over physical customer-traced templates. The most important advantage is that it eliminates template errors and helps avoid zipper stress, maximizing packing efficiency, and ensures strap compatibility with existing bags/frame features.

Can you do a seat tube bolt-on too?
Absolutely. Please add that feature in the Framebag Extras category
What about a full bolt-on bag?
For sure, you can add the downtube bolt on here, and then head to the Framebag Extras category  to add the top tube and seat tube bolt on.

Please note, we CAN NOT do a flared nose and a top tube bolt on. Those two features do not play nice with each other.

For intl. orders, how much is Tax and Duty?
Please add your gear to your cart and select the “UPS Worldwide Economy” shipping option. You will then see the exact price of Tax and Duty at the checkout page. This is paid in full at checkout which allows your package to skip customs and be delivered right to your door.
