Quality product that meets the criteria of my research (dimensions, comfort), ease of assembly, conclusive tests. Only downside the delayed delivery date following the misplacement of the product but hey it's summer.....

Confused over dropper post descriptions

2025/04/28

michael

I am confused over the Highline 3 dropper post numbers. Which on gives a 150mm drop ,with a 31.6mm diameter? Is it the one in the link below? https://www.tradeinn.com/bikeinn/en/crankbrothers-highline-3-dropper-seatpost-300-mm/139370179/p

Answer of Rodrigo

You need to select the "150-469mm" option! This one has a 150mm stroke! The 469mm measurement is the total length! Now I don´t remember if it is recessed or advanced! I think it is advanced! Please check the manual that you can find on the manufacturer´s website!

It is suitable for a megamo track 2019

Jordi

Does it fit a 2019 Megamo track size L?

Answer of Bastien

Hello, it is enough that the stem diameter is the same as the frame and that we can route the cable in the frame to take it out a little higher near the handlebars.

What are the remote controls compatible with this seat post?

Answer of Baptiste

All remote controls are compatible with this salt rod. It just has to be a cable remote.

Baz

Hello, I ordered a 150mm drop ,,diameter Crank Bros Highline 3 (30.9mm) seat post. I'm a bit concerned because in the product description it mentioned (in the specifications) the drop ,,is 80mm and (in the features) 100mm. I definitely don't want either of those, I want the 150mm. Can someone tell me what's going on with all the different drop ,,heights mentioned?

Answer of ILIAS

GOOD MORNING . YES I HAVE IT AND IT IS 150mm !!!

Answer of Rodrigo

Vx must select the option with 150-469mm travel! This one has 150mm of travel and a total length of 469mm! You can also check it out on the Crankbrothers website! I hope I have help.

Answer of Gary

I ordered a 150mm drop ,and that is what I received, so no issues. Just make sure you take care of the size you are choosing (length/diameter) in the drop ,down menu on the right side when placing your order. Thank you

Hello, I would like to know more about the specifications of this product, its exact measurements, offset, what is in the box and the characteristics

Answer of Cristian

The measurement depends on what you ask for in the dropdown, it is only the seatpost, it comes without a remote.
