Folks,  
 
Is there something on the market, like a bracket or rail, that protects a derailler system against a right side fall?  I'm thinking that it would mount on the rear frame and extend over the derailler system to serve that function.   Maybe rigid panniers would serve this purpose?? ....or a right side training wheel??
 
Thanks,  
Travis

That's an interesting idea, although it might need to be something that goes several inches front to back, to protect the derailleur across it's entire length of travel...  and stiff, so it doesn't get shoved into the D anyway.  Tough to mount something securely, since it hangs down below the frame, but an idea worth tinkering with.
