If you were in a situation where a trailside rear derailleur fix saved your epic ride, whats the most creative or unconventional material youve used to rig a temporary fix, and how did you MacGyver it to get back on the trail? Was it a stick, a rubber band, or something even more unorthodox? Whats the most ridiculous thing youve used to salvage a ride, and did it actually work? Did you find that the fix gave you a newfound appreciation for the art of bike hackery, or was it just a desperate attempt to avoid a long hike-a-bike back to civilization?
