Alpine Luddites frame bag

Unlike seat bags, I don't build stock sized frame bags. there are too many variations, tube diameters, and materials to make stock bags work well for most customers. all it takes is a quick look at any good independent bike brand to see the reality of stock sizes.  so, while you have to get in line to get a frame bag, rest assured you will be getting exactly what you want.


The single zipper bag is designed for any sized frame. The frame bags are typically made from  Dimension-Polyant laminated X Pac fabrics.


  • VX51, 500x1000 Denier Cordura nylon laminate, is used in high abrasion areas, around the perimeter where the bag hits the frame.
  • VX21, VX42 nylon packcloth laminate, is used on the side panels.
  • #10 YKK water resistant zips used on all load-bearing openings.


Each bag is custom made. I will need the following:

  • frame brand, model, size & year
  • inside length of the top tube, seat tube, down tube and if you have a bigger frame the head tube.
  • for Carbon, Ti or Alloy frames I need accurate tube measurements as shown in the photos. if the changing shape at any place on the tube I need the measurement and its location marked on the triangle tracing. Steel frames have less variability in tube size. I have a fleet of steel bike to work off of.
  • For full suspension bikes, I need tracing of your front triangle. I will also need any strap locations /bottles cages w/ bottles so we have no fit issues.
