Stupid cranks. Or should I say stupid human
Got the spindle, chainring, bearings and right side all set up. Moved on to something else, came back to throw the left side on and realized I had the arms swapped. Tear it all back out for a do over
I feel your pain. Here is photographic evidence from the early 70s. I had relaced the rear wheel myself and when the bike was flipped I installed everything backwards. I still remember tearing it all back down for a do-over.
EDIT: And YES, that is foil tape on the sissy bar.
