That shot above is point of destruction no. 2. Point no. 1 was a bent connection tab, which was straightened gently but still the effort went beyond the tab's yield and so it cracked when returned to quasi-straight alignment. Would you trust such a weakened bit of aluminum to hold integrity under pedaling loads which sometimes join with the load-shifts under suspension dynamics? Would you risk sucking a derailleur into a rear wheel? Or would you just ride as if chainless, pushing the remainder of the climbs and never pedaling other than to ratchet for rock avoidance? You have approximately 2 hrs left in the ride at this point. What do you do?
Get pushin', pal.
After you rig the rear der with your friend's wizard-like insight on a new chain routing that lets you omit the dropping-to-the-inboard-side-constantly feature of missing that lower inner cage aspect.
I dunno, maybe I should have called search and rescue? The rock wasn't apparent! What are these dangerous rocks doing in this trail?
They're called the Rocky Mountains, sir.
Never mind that. I expect a trouble-free experience no different from a mall-walk.
