I'm sure that Gary can list more reasons than I. I've come to the conclusion that they may be more efficient for bent riders, because we tend to have slower cadence due to the position we are sitting. More leg weight to lift up and down. Spinning can be more fatiguing on a bent than a wedgie. These are the perfect cranks for mashers. Constant all on power all the time. Frank now tends to pedal at a slower cadence but with more power per stroke. At the same time, the cardio vascular has slowed at the same given wattage output. It does take some time to adjust to them to bring your heart rate back up to previous levels. At the same time the wattage output goes up further. This means faster. Most of you guys don't race though, so it may not be of any interest to you to go any faster with less percieved effort.
