Bag Spacer Tubes

These are thick cardboard tubes that come from the rolls of tape we use here to pack boxes, but they make good spacers if you cut them down. I don't know how they'll do in the rain, likely not that well, so use them on your sunny day bikes.

Use a hacksaw to shorten them, and a rounded file to slot them for handlebars, seatpost, or headtube. Run the straps on the inside of the tube so they stay in the position you want.

A little over an inch and a half wide and almost four inches long. Cut one down for at least two spacers.
