The B&M shifter unfortunately has the cable come in from the front. I had one melt. After I replaced it, I used an insulating thermal heat sleeve like what is offered by Jeg's in the mini-catalog I just got today (page 17-A lower left). Their stuff comes in sizes from 1/4" to 1" ID and lengths from 3' to 10'. It may be spendy, but how much fun is it to buy new cables and replace them?
