Total Noob Question- Bash Guard + Shifter
So I am going from a triple in front to a double with a bash guard. What (if anything) do I have to do to prevent my front derailleur from trying to shift onto the bash guard. Is this is a problem? I know the obvious answer is "don't shift there", but sometime in the heat of the moment it will happen.
Does anybody make a twist shifter compatable with just a double up front? Could I use a road bike double (Sora, 105) for the front derailleur? What has everybody else done?
