How to: Replace a damaged spoke from a R1200GSA wheel. 

You can spin the wheel and eyeball whether or not the wheel isn't true. It'll wobble instead of smoothly spinning. If you're too rough changing the tire you can also bend the lip of the wheel. Not common but I've heard of that before. Here I was not careful and pried the tire iron into the spoke and dinged it. Luckily for me that's all I messed up. Don't over tighten the spoke and it should be fine since it's only one. Say you bent like 6 spokes then it comes into question whether you need to check for trueness.

@@ADVPosers I appreciate the reply. This was from using a rabaconda tire changer. Put some pressure on the spokes when breaking bead and can only tell that one bent. Wheel is fine. Will try replacing the single spoke and give this a try. Thanks.

@@2525tyler Yea sounds like what I did to mine. It was actually fine as is I rode around and didn't notice any wobbles I just saw it when I walked by. They're cheap enough to replace so no biggie, just be more careful next time.
