Maybe not an issue...
*Even Lance Armstrong, for example, when he pushes 500 Watts at 100 RPM, develops force peaks at each pedal stroke of less than 60 kg.
Force peaks become more important in acceleration and in spurts: at 900 Watts of power with 100 RPM, the force required for every pedal stroke surpass 100 kg. But at this power level the ideal rate is around 125 RPM, thus reducing the required force to about 80 kg.
The best cyclists in sprints reach power levels close to 1500 Watts, which at 100 RPM require force peaks of nearly 180 kg! *
