PERFORMANCE

Whenever riders are pedaling hard, like when climbing, fighting headwinds or just accelerating away from a traffic light, the frame provides a significant benefit. During the down stroke, pedal force stretches the steel down-tube and the bottom bracket extends slightly, briefly storing pedal energy. As the power stroke nears the bottom and pedal force fades, the stored energy in the stretched down tube is released into the pedal stroke. This release slightly extends the duration of the power stroke and thereby makes pedaling a little easier, particularly in higher gears. Though this phenomenon is more noticeable under hard pedaling, even moderate pedaling is aided during every pedal cycle making long rides a little easier as well as more comfortable.
