This high strength cardboard box is the same size as our hard case and is an economical method of packing a bike for occasional airline travel. It can be used with or without our box cover. When used with the box cover, it makes an attractive yet inexpensive option. For maximum protection, we recommend that up to 4 compression members be used with this box. It measures 26" x 26" x10". Box (without the black fabric box cover).
