EXA Form Speed up-27.2mm

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.

It's awesome, it's ok to set it to the desired position when you can spare one free hand.Good quality so far after a couple of rough rides.

I’m happy with it for what it is. I only use a dropper on the trails and this is super easy to install and remove. It takes a lot of pressure to get the seat post down. It doesn’t just shoot up either, but when you know you have a descent coming up, it works to get the saddle out of the way. Adjusting it slows you down, but it’s still fun.

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.

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.

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.

The dropper worked as expected, was easy to install and operate.
