Can I use a seat height calculator for a mountain bike with a dropper post, or are there specific considerations that need to be taken into account when determining optimal seat height for a bike with a dropper post? Im wondering if the standard seat height calculation methods, which typically involve measuring the distance from the center of the bottom bracket to the top of the saddle, are still applicable when the saddle height can be adjusted on the fly. Are there any specific formulas or guidelines that should be used when calculating seat height for a mountain bike with a dropper post, and how do factors such as riding style, terrain, and dropper post travel affect the optimal seat height?
