I say pin it in place, rig up some kind of return spring, and 2-foot ratchet-boost your way down the trails from now on! Zoom zoom!
I forgot to tighten them up enough before I tried looking for my chain breaker, which I ultimately realised I had left in a park. Then I went for a ride, hucked some rock ledges to flat and rounded the spindle. I replaced the now with my spare set, as well as the tyres because one close call is enough.That is an impressive bit of work. How did you get there?
