Installing a Bash Guard

 This can easily be done on-bike. As long as you can reach those nuts on the back with a large flat-head screwdriver (even if only 1 at a time) it is a 2 min swap. A bit more awkward to hold it together as you get the first 2 screws in, but a lot quicker than pulling the cranks. I routinely swapped big/bash on my TruVativ Hussfelt cranks without ever pulling them off the bike.
