This is what we call minimum exposed post. You need to have 6 1/4 inches of seatpost in your up position showing to run a 3 inch drop post. You need to have 7 1/4 inches showing to run a 4″ drop post. Measure from where the post goes into the bike to the seat rails. When you lower your post. It will then drop the 3 or 4 inches depending on which one you have 3″ or 4″ drop. You can see a pic of this on the comparison chart located on the sales page.
Yes, The Gravitydropper Turbo an Classic can be run with the unit facing forward or backward, whichever you prefer. If you plan to run the unit facing backward, specify that when you order so that we will use the longer cable.
The GravityDropper Classic and the Gravitydropper Turbo can be raised or lowered in a fraction of a second by pushing the switch located on the handlebar. This is done while still pedaling. The Descender requires the rider to take their hand off the handlebar to pull the knob. This can be done quickly, but again, the rider must be in a place where they can take their hand off the handlebar. The Gravitydropper Classic can be raised by pushing the switch and tapping the seat or by sitting up while pushing the switch. The Turbo can be raised the same way or by just pushing the switch. A tap is not required but can be done.
