ENVE has found that a dropper seatpost can enhance the gravel experience and that 40mm of drop is just the right amount for most gravel riding and racing. A dropper post allows the rider to lower their center of
gravity on descents which can result in greater control and therefore confidence. While designed primarily for gravel riders the G Series Dropper allows XC riders and racers a lightweight dropper with just the right amount of drop.
