Maximum Seatpost Insertion Depth On A Medium Frame?

[Rideit]

Thanks in advance. My bike is in transit, but I would love to know what the longest post I can run is. I’m 5’ 8”, but I have an almost 33” inseam, this is definitely an issue, lol! (I run a 210 easily on a medium Rocky Mountain Altitude).
I know the Amflow seatube has a kink.
Thanks!

Read the manual, it's in there

250mm

I'm thinking about an Amflow and with a Medium the max seat post dropper is 150mm.

If the max insert depth is 250mm then according to the specs it can take a 175mm AXS B1 (just)

@Rideit how far is your base seat post from max insertion to get your ride height?

Can anyone with a medium show the seat height with the post fully inserted and the dropper fully up?

Take out the tape measure.
- measure the seat height from the middle of BB to the seat rails on your current bike
- plug in numbers for the dropper you'd like to get into above to see what you'd need

I am running a OneUP Components V3 dropper 31.6 x 180 that is fully slammed on my medium Carbon PL. You just need to be careful to ensure that the cable and seat post actuator sit nicely behind the charging connector in the seat tube. It is best to remove the battery and drop the motor to route the new cable. Saves lots of time and effort. 180 mm puts the seat a little high but the shims reduce the extended height and still allow a very low seat height when retracted.

It was well worth the effort for a smooth and super fast dropper that gives a really low profile then the seat is in the dropped position.
