So I broke my E*Thirteen E*Spec Plus Chain Guide at the weekend. No idea how, I was riding up a fire road and heard a crack, I looked down and it was sitting funny over the chain ring and came off in my hand when I tried to put it back. Anyway, that's not important right now. What is important is sourcing a replacement, either another E*Spec Plus, or something better. Has anyone changed their chain guide for something else?
