THE GRIP — BARS

To cut with a hacksaw a thin tube, not securing them, very uncomfortable and tiring. However, if you have no grip on this case— do not worry: help out a pair of wooden sticks, with one end tied with twine or wire. You can sdelatj the bars cross the hollows for the pipe and place the coupler to attach the rubber pad to facilitate the unclamping of the bars with the release of the tube.
