I keep reading how the design of the GS wheel allows you to replace spokes on the go, without remvoing the rubber. My questions are: Is it possible to break or damage a spoke without also damaging the rim? If my spoke is broken or damaged, won't I have bigger things to worry about? Is it really realistic to damage only a spoke, without damaging the rim? If so, how? I'm not being flip here, I'm just trying to learn.
