I have many happy miles on my Ksyriums. No complaints what-so-ever. Recently while shopping for wheels for my MTB, i was discussing Mavic hubs with a local shop tech. He mentioned that there was basic service that needed to be done on the freehub body regularly...something about removing the body, and oiling with a 3 in one oil??? Anyone know what he is talking about, and if this is necessary?

This describes the procedure although it does not include instructions for your specific hub. Being sort of new to road bikes again, I'm not sure how often it should be done. For MTBs, I get a lot of different answers, with the most confusing, what lube to use.
Hope this helps. Please post a followup, I have some Kysriums too and would like to know.

It is really important to service the freehub on Ksyriums/Crossmax/ well all mavic wheels. If you fail to service the thing about every say 1500 miles (my own recommendation) you can wear out the freehub body and the pawls inside. I lube mine with mineral oil, it has a good weight and stays fairly clean inside. The procedure is fairly simple.
1. For Ksyriums first remove the wheel and skewer.
2. The left axle end should pull out of the hole it fits in (can be stubborn)
3. Once removed there is a large hole that a 10mm Allen wrench fits in.
4. The drive side takes a 5mm wrench, put both wrenches in and unscrew the drive side bolt.
5. Lift the bolt out and then CAREFULLY pull the freehub (no need to remove cassette) off of the hub being careful not to go too fast because the pawls and springs will fly across the room if you are not careful.
6. Clean everything out and then replace the pawls in their grooves with the springs attached to the pins on one end and the holes on the other.
7. Relube everything with mineral oil then slide the freehub body over the pawls as you squeeze them together.
8. Use the 5mm and 10mm wrenches to tighten everything up again and pop the axle end back in the left side.
9. Spin the freehub and listen to the deadened ratcheting sound. Nice, now you can sneak up on your riding buddies again.
