The Boat/Rock Brainteaser ft Simone Giertz part 2/3

for whom it may concern! The left pedal of a bike and usually the right cup in a threaded bottom bracket are reversed to a LH thread, because,,,,....
The thing sinning in a left pedal is its axle. Pedal Axles spin backwards of our pedaling direction. The left pedal axle is going counter clockwise as the pedal faces the same direction at your foot. Threading Counter clockwise encourages the spin direction to tighten the pedal instead of it loosening (and falling off)(and it would loosen). It is already oriented to tighten the pedal as you ride on the RH side. Threads in Bottom bracket cups are backwards to the pedals because the Axles in pedals spin backwards as axles in a bottom bracket are spinning forwards. Hence the LH cup is standard and the RH cup is reversed thread on the threaded bottom brackets.
