I just got a cheep one from amazon. My son is 56" tall and weighs 80lbs and it works well. Its works well and is easy to actuate. Here is a description if you want to search for it.
MiOYOOW Dropper Post, 30.9/31.6x345/395mm Hydraulic Seatpost Travel 100/125mm
Looks like it can be fully inserted into the seat tube. What ‘s the lowest collar to rails measurement with the seat all the way down and fully inserted into the set tube?
Update: I ended up ordering the KS Rage-I dropper….it’s supposed to be 142g lighter. Should get it installed Sunday.
@dustindirt in case you don’t know and are interested. The Chainstay protector for the other rift zones fits the Jr/26 as well. I took off the stock tape/protector and added the nicer rubber one that comes on the bigger Rift Zones.
For reference, my son is 56" tall and the post is inserted all the way down.
Thanks! My daughter is about 57” and installed the KS rage about an inch above the seat collar. Only thing I don’t like about the KS is that it seems to bind if you push down on the rear of the seat. If you push down on the middle or front of the seat it goes down much smoother…odd. I had ordered the official Marin rubber grommets for the RZ Jr. But ended up just using ones from my extra set or regular rift zone grommets….they were tight but they fit. I’ll swap to the Junior ones if/when I ever replace her dropper. Looks like I ordered one of the last ones because it’s no longer in stock lol. https://store.marinbikes.com/collections/parts/products/17-18-hawk-hill-nail-trail-dropper-post-grommet-kit-3pack?variant=5456244146207
BTW what made you decide to go 24”? I went 26” for my daughter since it was replacing her 24” and glad I did. Don’t think the 24” would last her very long.
I just thought that the 24" would fit him better and be a easier transition from the 20" wheels he had on his last bike. I also liked the lower range the 24" offered on climbs. My son doesn't charge stuff on his bike like he does on his dirtbike. He will go up and down things on his dirtbike that, at my age, I have to reluctantly follow and hope for the best. I used to race mx, now I have a morgage....

The good thing about the bike is that you can upgrade to the 26” whenever you want! I’m curious how readily available the wheel sets are?
Upgraded to Bike Yoke Revive dropper and xtr crankset. Currently now weighing in at 30.78 lbs. I was hoping to install the stock FSA grid crankset on my daughters RZ 26….but they’re a wider model than I thought they were at boost 148/157+ and probably a 175mm Q factor.
Nice build! Have you done something else since upgrading the shock? I can’t tell from your pics if you’re running the KMC chain and don’t see a build list posted. But if you haven’t already I would consider swappping out the KMC chain for a shimano chain and crankset. Will pedal smoother, shift a bit better and shed some weight as well. The FSA comet weighs a bit more than even the grid that comes with the RZ3.
I bought the RZ3 thinking it would hold off the urge to upgrade…boy was I wrong. In my quest to shed weight I thought I was done tinkering after upgrading to the XTR crankset…but yesterday the 10-51 XTR cassette popped up on my LBS’s website and snatched it up lol. I’ve been scouring the web for months, for a shop that had it in stock and couldn’t find it in stock anywhere. Hopefully I’ll be done tinkering for now too. I’ve been looking for a WTB Volt titanium saddle but can’t find that anywhere as well. Only thing left is shock and fork….but I’m satisfied with the DPS and Marzocchi Z2……for now lol.
