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 in waterproof VX21 fabric in your choice of colors. the perimeter is of the bag is VX50/100 Cordura faced fabric for excellent durability and waterproofness. Velcro sealed hydration port is standard.

I recomend using side loading waterbottle cages with these bags.


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 custom size please send me , bike size and model, your inside top tube length and head tube length, if you have one.
    • order by the inside length of your top tube. if in between sizes I always recomend going bigger, a squashed end is better than under wrapped velcro.

 Note: stock sizes in available without my normal wait time, custom go on waiting list.
