Cube Aim SL 2021 dropper seat post

Hi All,
I'm very new to mountain biking and have had some good advice to fit a dropper post to my bike. Now, I know my frame has internal routing but I can't see where it would enter the seat post tube so my question is will an internal post actually fit or is it external only? This bike has 3 sprockets at the front (referred to as 3X I believe?) so there's no obvious cable route in this area of the post.
If anyone has experience of this particular Cube bike could help me out I'd appreciate it!

Your bike does have internal routing for the brakes and shift cables, etc. but unfortunately that doesn't mean it has routing for an internal dropper post.
Not having relevant holes located in the frame for a smooth cable route means you would be better off buying an external dropper or possibly an 'under the seat lever' without a cable like the KS E10 for example.
Worth taking a close look as you could possibly have spare existing external cable guides to neatly route the dropper cable to the handlebars. 😉
The photos on the website show spare ports at the top of the down tube so the dropper cable routing is probably to enter there and then loop inside the bottom bracket up in to the seat tube.
That’s a fairly common dropper post cable routing and isn’t too difficult to do.
And it all promised so so much”

They do droppers that are bottom entry and also top-side entry. The come in a range of seat tube sizes and also dropper travel. They are much cheaper than the high end droppers like the Reverbs, but don't let that put you off, they are great quality and get good reviews.
Start here to look. https://www.chainreactioncycles.com/seatposts
When you open a web page you will see a picture, That picture will have several other options and one will be a dimensioned drawing that will enable you to determine if the dropper is the right one for your bike. For example: With the dropper fully extended, yet the body fully inserted into your seat tube, is the saddle too high for you? Yes I know that you can use the dropper function to drop the saddle, but having to do that every time you use the dropper becomes an irritating chore after a while.
If you have the misfortune to have an awkward seat tube diameter, all is not lost, buy a smaller diameter dropper and use a shim. You can buy shims of all sizes on the web.
Thanks again for the advice/help mate
future dropper upgrade' or a spare cable port on any pics for your specific model.
If you do find a suitable dropper but only internally routed there is the opening under the bb shell you mentioned where the other cables come out so perhaps you could bodge some more exit space and then go externally under the downtube? 🤔
In this case I personally wouldn't like such a tight cable turn around the bb even if it is physically doeable inside your frame. 😬

PS: Kind Shock (sometimes called KS) also do 27.2mm droppers.
I'm getting an external one, porbably a brand-X as I've seen the link in Steve's post and that looks very reasonable. Cheers for looking though, appreciate it!
Compare that to the multiple Reverbs that I've had that all failed just after the two years were up or within a few months of being new and Brand-X droppers do well.
I just sold a bike that had a Kind Shock dropper on that after two years developed a little bit of side to side seat wobble, but never got any worse in the following six months until I sold it.
I would certainly buy another Brand-X without hesitation. They seem to have hit the Goldilocks spot of just above "cheap as chips" but retaining the high quality and good performance that should come with the premium brands but sadly is not guaranteed.
