Don't bother - I have a broken shaft that I picked up off the ground at a kayaking event - Lendal Grade 1F (25% fiberglass, 75% carbon) Measuring with a beat up old volt-ohmmeter, I find that the resistance from one end to the other varies from 20 to 40 ohms depending on where I place the probe at one end. It would appear that there's a slight variation in resistance across the fibers. The length of the piece is 17.5 inches.
