My wires are not secured at all, but I'm wonder if the pressure from the bigger wire on the plastic, when rolling around that curve, will be too much for the chain? Then securing it to the chain may alleviate some of that pressure? I would definitely try in without the wires attached first though.
that's why i was looking at the metal stuff.... now that you brought it up, i'm not seeing why you would have to secure them if it all tracked nice...
they actually make those in fully enclosed, 4 side, feed-thru style too... i ruled that out initially, but maybe I should take a peak at em tonight...

basically perm hernia pain for about 3 yrs running now, 6 knee surgeries always ready to wreak havoc, I could barely walk going into the week, and then i shredded my lower back on weds..
