2.92 Cuben Fiber Hybrid


This fabric is a 2-layer laminate; one side is cuben fiber, the other is polyester. The polyester adds strength for stitching and abrasion resistance. Default is with the polyester facing inside to better prevent abrasion holes from the contents of your bag. To have the matte polyester side facing out select that option in the dropdown menu. Visit the Framebag Features page for more information on your build options.



Our Cuben Fiber 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 Cuben Fiber is a hybrid material, made with a 50 denier matte polyester face mated to a shiny dyneema (aka cuben fiber) 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). If you would like the matte polyester side facing out, please select this option in the drop-down menu.

Base features:

  • Waterproof zipper tape – Strong molded teeth – Smoothest action zipper available
  • 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.
