Which Dropper Post length is right for me?
In order to determine which dropper post fits you, simply measure the distance from the center of the bottom bracket to the top of your saddle on your current bike. We recommend to choose the biggest amount of drop possible. More drop is more better.
The minimum distance from the center of the BB to the top of the saddle, measured in cm with an Ergon saddle (4,5 cm height) and the MY21 Fox Transfer seat posts.
