This is a bad photo but I ride a small frame with 650b wheels and my AEROE cradle (which I mounted on the fork crown using diy hardware) can hold a larger dry bag than the 10 liter bag shown. That 10 liter bag has my MRS tent, tent poles, and other puffy items.
And with those 30” straps there’s plenty more room on top to strap other items…like a camp chair…
