[edit] threading to attach pedal to crank arm?
The page has the following snippet: "...prevent it from becoming loose by an effect called precession. Although the pedal turns clockwise in its bearing..." and I wonder if the author is referring to the right or left pedal here. My guess is that one would turn CW and the other, CCW. —The preceding unsigned comment was added by 76.192.216.81 (talk) 19:22, 13 March 2007 (UTC).
- That snippet refers to the left pedal and crank arm. Yes, the left pedal turns CW and the right pedal turns CCW.
- I've tweaked the text to read "Although the left pedal turns clockwise on its bearing relative to the crank arm (and so would seem to tighten a right-hand thread), the force from the rider's foot presses the spindle against the crank arm thread at a point which rolls around clockwise with respect to the crank arm, thus slowly pulling the outside of the pedal spindle anticlockwise (counterclockwise) because of friction and thus would loosen a right-hand thread." -AndrewDressel 01:22, 14 March 2007 (UTC)
