I need some help and advice in disassembly of the Krysium SL front axle.I trying to replace the front axle because it seems bent.I got the axle,but I can't remove the part where the fork dropouts seat.There's two of them the other one just pops out and you just unsrew the silver round nut with the mavic tool.The other side you need to insert a 10mm hex wrench inside the axle and a 5mm on the other end,but this one on the other side would not budge at all.I tried eveything,even broke a 5mm wrench and rounding out the 5mm opening from too much force.Is this part press fitted on the axle?Is this black part one piece or two serving as a bearing cover and dropout that screws on the axle?What's the Mavic part # for this?Any ideas what's going on?
Seems like no one has this exper., keep us posted (nm)Paul

Mavic has a site for its dealers with tech info. Fortunately I've got the login and password for you. Go to the products section, then choose Road. The Ksyrium SL is listed. You can download the instructions for axle and hub disassembly.
login: mavic-com
password: dealer

I also added the link for this pdf-file. It works without login in, I think.

Hope this helps you

Sorry, the link didn't work right. I'll put it in the message.Dirk Lenart

direction when loosing the axle end screw. You don't unscrew the silver round nut till you unloosen the axle. Let me kow if you can get this info okay. I went to the home page, and then printed out ever page on the ksyriums.

Yep, good idea. I did that immediately after I discovered the site. I know the French are lazy, but even they may discover their site is open to non-dealers.
As a matter of fact, they should give this info to the customer as well, with the wheels for instance.

bashing. People were really geting riled up, and i guess I started it by using the term frog. Oh well, once in awhile need a little diversion from bikes.

I thought the bearings would just pop out, but it shows special tools for getting them in/out. Have you ever replaced your bearings? Heliums look to be simplier. I have a friend who broke a rear spoke on his Ksyriums after 1,000 miles. It went so bad out of true, he couldn't ride it. Hi tech/low spoke count wheels scare me at times. I think after these wheels go, it's back to the basics for me. Have to be able to repair these wheels when out riding.

I agree, the site should be open to all owners of mavic wheeels, but you know they are out to hellp the retailers make money.
Screw the consumer.

Again Dirk, thanks for your help

I changed the bearings of my Mavic Crossride rear. The same system. My LBS advised me to use a punch to get the bearings out. If you look closely at the Mavic tools, the one to get them out is basically a long punch too. If you hit the inner ring of the bearing at several places along its circle, the bearing will pop out. Don't hit the cartridge in the middle or you'll destroy the thin metallic side cover of the bearings.
To get a new one in, you can use the shaft of a screwdriver. The metal end of the screwdriver goes through the bearings into the hub. The shaft stays on the outside and rests on the inner metal ring of the bearing. Now you can punch safely. It takes some banging to get it in, don't be afraid. Be sure the bottom of your wheel rests on a flat surface. Otherwise you'll bang your wheel out of true.
Truing a Ksyrium is not difficult with the tools that come with the wheel. Although you must be familiar with truing, better still, building wheels. A truing stand is very helfpul too.
The Mavic design is such that when you want to clean your hub, you'll have to take out the bearings first, otherwise you cannot insert the 12mm hex wrench from the inside.
So, in order to maintain you're own wheels (which I can agree with wholeheartedly), you'd better get used to removing those bearings.
Don't be too afraid of those costly wheels. But on the other hand don't be to brutal with them either. Rethinking every move you make and the possible concequences is a must.
I love my K's. But I've recently built me another wheelset which feels equally nice. Mavic Open Pro's on Dura Ace hubs laced with DT Revolutions black front and left rear. Right rear with DT Comps. Actually my front wheel is lighter than my tubular Ksyrium front.
