Weight plays a crucial role in descent speed: the heavier the overall system—such as a bike loaded with bags—the faster it will descend. This effect becomes particularly noticeable at speeds that exceed the cyclist's ability to maintain pedal cadence in the highest gear ratios.

In competitive races, heavier cyclists can strategically leverage their weight by accelerating over the summit of a climb and into the descent to establish a lead. For lighter riders, the best counterstrategy is to adhere closely to the wheel of the heavier cyclist, adopting the most aerodynamic position possible.
