lol i like how you have half link chain that designed just for this reason but you still have your back rim far back at unsafe part drop out. i understand you may not like having to take you master link out or slipping your crank out of your sprocket to take off your back wheel off but i would suggest you try that because where you have it tighten to your drop out looks to me like an accident waiting to happen. the half link was made just for this reason so you didn't have to used that much the drop out. i hope you take this tip as good thing just trying help ya out bro like i'm not trying to be dick or any thing but have fun ride safe bro.
