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.

I’ve been using dropper posts since I got my first mtb, and I’ve used a bunch of different brands and setups. This dropper post, apart from the obvious low price for the quality you get, is a real game changer when it comes to cockpit setup and tidying everything up on your bike. It takes a little to get used to since you don’t have the lever on the handlebar (every other dropper I have used had this feature), but once you get the hang of using one hand to drop it or raise it up, you’re good to go. Works great, and the 150mm length works great for me, it can definitely beat up other much more expensive droppers with the same length.

After doing a lot of research, this is the cheapest decent office chair style dropper post I could find. The first one was pretty difficult to get it to drop, even with all my weight on it (180lbs.), so I sent it back and got another one, which was definitely easier, but sometimes I still have to pogo stick up and down a little bit to get it to drop, even after putting some stanchion lube on it. I read a lot of reports of the cheaper dropper post failing/breaking, but after some pretty extensive testing, this one's been pretty solid. For the price point, I definitely recommend it. It gets the job done.Did you find this review helpful?

Extends directly into my ass. Perfect.

I added this to my e-bike so I could drop my seat when putting both our bikes on a car rack. My wife’s handlebars wound rub on my seat unless I dropped it down. Now I can drop it without any tools in a second. This drop post also allows others to try my bike with out the hassle of getting tools to lower the seat. I have only had this installed for a few weeks and a few rides. It seems solid and time will tell its durability.

Worked well for about 5 rides and is now stuck in the down position. Unable to get it to return to full extension length. Outside of return window by about 13 days. Buyer beware...

i have the KS Eten Lever version on my gravel bike so am familiar and comfortable with how they function. i picked up the 100mm range for an ebike that is hard to dismount at the proper height (despite that size charts put me on this bike). it also comes in handy when hopping on the bike in non cleated shoes when a lower saddle is called for.this is similar to the Eten lever, albeit a bit slower movement and heavier. installed into the seat tube fine, but it was super finicky on leveling the saddle. after an hour and a KS video, i managed to get the saddle level. first ride, the saddle bolt loosened up after 15 minutes. came back and lubed all the bits as the KS video showed and re-tightened the bits. have not gone out but expect when i do it should be fine. lost a star for weight and another for loosening. if it happens a 2nd time, this will be returned. it is unsafe for a saddle to come loose. i'll update if this issue persists or whether i sorted it. i have tried reaching out to KS mulitple imes without replies.

When I lower my seat for easiest mounting/dismounting, the seat is too low for optimum pedaling. The drop post solves this problem by allowing me to raise the seat once I am on the bike and to lower the seat to easily dismount. I considered a noseless seat but they have their own issues. I would have preferred the 75mm version (max travel ~3") but I could not find it anywhere. No instructions, but installation is very intuitive. I think this will solve my issue.
