Hey, so you made it?

I don't have access to my bike right now (lolz im just really lazy) can you give me the dimensions of the bolt? I'm running stuff on single speed and I sometimes almost always get too close to popping all my spokes!

 hey man, its just an m4 bolt, im not sure of the exact dimensions i just set the mech in my lowest gear, then just measured the size of the gap that the bracket needed to fill, admittedly it took a couple of attempts to get the bracket the right size! works perfect though
