on the ksyriums. I have oly one question from your writeup. I don't understand "--clean your hub, you'll have to take out bearings first, ----insert the 12 mm wrench from the inside". I don't have the picture in front of me, are we removing the axle at this point? What is the 12 mm for? How does the hub get dirty if everything is sealed?

I agree with you on your Open Pros, Dura Ace hubs, light spokes. hi tech stuff can be a hassle. My friend broke a K spoke on the rear, and the wheel was so out of true, he had to call for help as he couldnt ride the bike. I carry a kevlar string with me when using Open Pros (have World Class hubs, beautiful hub with a great finish), and thiswill true your wheel if you break a spoke. simplicity can be a great asset at times. Most wrenches won't touch the K's and just ship them out for repair.

You would be a great asset in our club. Again, thanks for your help. I'm sure it helped a lot of other people.

I live in N. Virginia, a lot of hills, beautiful countryside. Waht kind of terrain do you have in Belgium?

safe riding man

No, at this point the axle has been removed. I mentioned this to make clear the procedure for cleaning and re-oiling of the freehub when it gets dry and crunchy inside from riding in a lot of wet weather. Water and grit get everywhere, no matter what kind of seal. My Crossrides needed this overhaul after riding through flooded streeds. The freehub started to make loud metallic noises very regularly.

Mavic freehubs are removed by inserting a 12 mm hex key which connects inside the hub. To get the 12 mm inside the hub, you'll have to remove the bearings because the 12 mm is too thick to go through the center of the bearing cartridge. A lot of hassle for a simple operation. Shimano freehubs have a far better design. Just remove the axle and insert a 10 mm hex from the right.

Well, Belgium being part of the Low Countries, you can imagine we have a lot of flat land. The french part of Belgium, the Ardennes, have some nice hilly terrain. You may have seen it in cycling classics as Liege-Bastogne-Liege.

Nice of you to appreciate my help. Been after this for a few weeks for my own use. I was especially looking after some advice to adjust the bearings of the K's correctly with the tool. I was familiar with cup and cone hubs. No one, in whatever cycling newsgroup knew how to do it. Most people went about it as if they were cup and cone hubs. But this results in a wiggly front wheel, because the plate with the holes has too much play. No one dared to turn it until it touched the cartridge, afraid of toasting the bearings. When you've taken a look at a bearing cartridge, you know you can never toast it with a plastic tool. I was right, the Mavic website info confirmed my approach as you may have read. I'm certain that most people ride around with a wiggly front Ksyrium (due to the desing the rear wheel does no suffer from this effect as much). Check this out yourself!

Do you know of a similar Shimano site like Mavic?Paul

Yes, go to the Shimano Europe site. Just pick a product (for instance Shimano Dura Ace hubs. In the pop up window you get the chance to download pdf's with service instructions and an exploded view of all the parts. Very nice when you don't know how to put things together in the right order.
Thanks again, and safe riding! (nm)Paul
