OneUp Dropper Post Length Selector - 27.2

Looking to upgrade your dropper post? Easily determine how much more drop you can fit with two simple measurements. 

STEP 1 - Measure Dimension X on your current post. This is your current ride height. The distance should be from the top of the seatpost collar to the middle of your saddle rails.

STEP 2 - Measure Dimension Y by inserting a rigid post or tape measure into your frame until it hits an obstruction.

All measurements are accurate to the best of our ability based on published dimensions of competitive posts.  If you notice any errors please contact us.
