Yes, that's a garden hose and 3 binders
Works quite well, even when 3 chain rings were installed. I never lost my chain since then; and the clattering is lowered to almost nothing! You may consider that the C-Guide of Bionicon uses the same (much older) principle. All of my buddies use this construction, some with bigger hoses, other with the same.
It survived 300km and 2 bikeparks atm. And even if a binder will decide to fail, I always carry a bunch of em in my jacket.
