The Strikeforce Konvoy 4-Ball Bowling Roller bag is a premium bag with room to store four bowling balls, shoes and all the accessories you will ever need. The awesome removable top bag converts to a full functioning 2 ball tote! With the 5" Kruze urethane wheels, you will have the most stable ride in the bowling industry!
Will the small add on bag fit on the 4 bag.
Unfortunately the handle is wider and most of the add on bags will not work on the wider handle. The add on bags would work more for 1, 2, or 3 ball rollers that have the inline design and a little more narrow handle.
Does the handle collapse down to the top of the first bag or in the middle of the second bag?
If you remove the top bag then the handle will still be sticking up and would not collapse down when the top bag is removed. To better see this here is a link to KR's website with a video of the bag for more info: https://www.krstrikeforce.com/products/konvoy-4-ball-roller
