Cluster 1/2 Frame Bag

A partial frame bag. Perfect for long day rides, gravel racing, multi-day tours, fat bikes, and Brevets. Allows you to carry food, tools, extra layer and still use standard water bottle cages.

This simple bag has a #10 YKK waterproof zip and mud flap over the slider. Made of waterproof VX21(all colors other than VX42 colors) or in VX42 (black and grey) fabric in your choice of colors. the perimeter is of the bag is VX50/100 Cordura faced fabric for excellent durability and waterproofness. 

I recommend using sideloading waterbottle cages with these bags.


The Cluster comes in four stock sizes  and custom sized:

      • Small: inside top length 17", overall height 4"
      • Medium: inside top length 18.5"; overall height 4.5"
      • Large: inside top length 20"; overall height 5"
      • XL: inside top length 21.5"; overall height 6"
      • For a custom size please send me, bike size and model, your inside top tube length and head tube length, if you have one, and how tall you want the bag. most range from 3"-6".
    • order by the inside length of your top tube. if in between sizes I always recommend going bigger, a squashed end is better than gaps.
