Second hand bike. When refilling my tyres with tubeless sealant I noticed the cassette was loose. The whole thing came out pretty easily (as per the video). I thought the cassette needed tightening, but then noticed there was no freehub either (?). Which seems totally wrong. I think the freehub and cassette may be stuck together?
Bought the bike secondhand recently. The wheels are Mavic Ksyrium Pro Disc All Road, probably from 2018 as the bike is an orbea terra from that year. First time owning from either brand.
Would appreciate help with confirming whether there's an issue and how to fix it. thanks

I don’t know that specific hub, but you can generally pull the cassette off the wheel with the free hub with a lot of wheels.
You need a cassette tool and chain whip to unscrew the cassette lock ring. That will free cassette from free hub body. Once the free hub body is… free of the cassette.. you can try putting it back on the axel. It should fit on there pretty securely with pressure.
Some freehub can be pulled out easily without tools for easy servicing. When you put in your thru axle and tighten it, it will actually hold the freehub down as well.
I dontknow about this specific mavic wheelset but DT does this alot. You can pull out the freehub but with abit kore ressistance.
Also mavic hubs are very very durableand bombproof.ive seen mavic hubs which has seen lots of miles througoutthe years and no servicing and still running great.
You did not mention whether or not it works properly when it’s installed.
Nothing is missing here, as far as I can see. The cassette is installed on the freehub, which slides off without any tools – this is all normal. The correct endcap is also visible on the outside of the cassette, as it should be.
You can get full parts diagrams for that wheelset here: [https://technicalmanual.mavic.com/tech-mavic/technical_manual/data/mavic_tech.php?display=product&family=1010&subfamily=1051¯onu=21855](https://technicalmanual.mavic.com/tech-mavic/technical_manual/data/mavic_tech.php?display=product&family=1010&subfamily=1051¯onu=21855)
This video shows the service procedure for those hubs (turn on subtitles for English): [https://www.youtube.com/watch?v=qVQaguI2lHk](https://www.youtube.com/watch?v=qVQaguI2lHk)
The ratchets in the hub are a wear item – with those wheels being ~7 years old, it’s probably a good idea to replace the ratchets to start your season. Part number V2251701.
I wouldn’t want that falling off during my ride.. if you can take it off with your hands (& by extension you need to ask the internet…..) This is probably bad, yes. Drivetrains are kinda important if ya are new to bicycling 🥴
