EXA Form Upgraded Speed Up 27.2mm/30.9mm/31.6mm Cable-Less Hydraulic Dropper Seatpost, 100mm/120mm/125mm/150mm Travel Dropper Post for MTB/E-Bike/Road Bike

I recently bought a Juiced CCX e bike which stands taller than my pedal road bike. Road bike measures about 29 inches from center of seat to center of BB, along the seat post. In order to maintain that comfortable spread, my seat ends up being almost two inches further from the ground, and I can barely touch the ground with my tip toes. This is not good for an 80-year-old man on a 65+ pound bike. This dropper post allows me to lower seat to easy mount/dismount position, then once on, rise to my ideal riding position. It might not be ideal for a mountain biker who needs to raise and lower the seat more often because it is a little awkward to grasp lever under the seat, but for someone like me, it's a simple, affordable solution. It also seems very well made, works like a charm when I ease off the seat and lift the lever, I can hear a slight sound when the seat extends fully.

Es una forma bastante sencilla de instalar un droper en la bici. Lo he utilizado un par de veces y es funcional, aunque para accionar la palanca debes ir muy lento o detenerte por completo. Es un recurso muy útil, sin embargo tiene desventajas al no tener mando en el manubrio. Si buscas agilidad no es la mejor opción pero si tienes tiempo de hacer detenerte para subir o bajar el sillín, entonces es perfecto

Easy install. Works perfectly.

Was getting hard for me to get my leg over the seat when mounting and dismounting, with the seat at the correct height. Now I lower the seat to get on and off and raise to ride.Seems really well made. Working smoothly. Just remove original seat post, transfer your seat, insert new post with seat, extend, adjust to your ride height, compress to get on, release, ride.Measure the original seat post diameter to make sure you get the correct dropper post.

Works great - but heavy and rusts in salt water. Used this for my hard tail I have at the Boca Chica Launch pad for work, after a few months the hull had rusted. Very harsh environment there though.
