Kinda sounds like a hasle, i think ill just leave it be, and keep and eye on my chain. TM design works makes an awsome chain guard + slide in one, but heres the thing, the last time my chain fell off when i bound up it got caught on the the front TM side I have on the bike and the chain came nowears near the case, i think they deisgned it to do that, its made up of that white indestructible plastic stuff and the chain barley even made a dent it it!!!
