+1. box cut off is 108"
The max frame you can fit in a 108" is 23"/58cm...maybe on a good day you can fit an under size 24"/60cm. The key to this is laying the frame on its down tube..you need the DT to be flat against the bottom of the box. Without doing this there's no flippin' way you'll hit the 108"
It just cost me $65 to ship a frame from Tampa to Colorado. Unless your shipping an old Schwinn 20lbs is way too much. 15 pounds packed is about right.
