I have broken (torn by kite lines) the polyurethane tubing for the leader line on an old 2010 Cabrinha SB. It has 2 channels: one for the leader line, and the other for the safety. I have had no luck finding spares, and even if I did, it appears that I have to buy the QR, the actual line and stopper just to get the PU tube.
Does anyone know the general specs for this tubing, or where I can look for it? I don't even know what to ask for, but I am guessing it is used for electrical cabling?
Or... can I repair the PU tubing somehow? Make a clean cut and glue/sleeve?
