Wheelset Mavic Ksyrium help

Not sure where best forum for this post.
I recently purchased a bike with Mavic Ksyrium Wheelset.
Wheels need trueing so purchased the correct spoke wrench and on my first two attempts to adjust, the bladed spoke nipples broke by twisting off. Maybe this is a common problem with those nipples? In any event, I am asking for help before I attempt another. Those two spokes needed adjustment so I will probably need to get more of those nipples and replace, which is much more painful than just trueing. Im worried that this will be a common problem. They are nice wheels/hubs so I would like to get them spinning more true.

TIA for any advice

Crescent wrench. To hold the spoke in place. Expect some sort of spoke prep to gum things up. Purchase extra spokes just in case.

I had to replace some spokes on a bladed pre-built wheel recently. Had to just cut them off eventually, but the wrench was a lot of help when putting the new spokes on. Get one of these to check the tension, and match it up with the adjacent spokes.



Someone else will probably come along later with better advice, but that's how i did it.

When truing bladed spokes I put some electrical tape on adjustable wrench to hold the blade in place so it doesnt twist while i turn the nipple.

Unfortunately you're going to learn about mavic replacement spokes and their infamous unavailability and price.

I've dealt with this on two Ksyrium SL wheels. Spoke nipples crumbling when trying to use the wrench is common on these. I've had some success soaking the nipple in penetrating oil. My LBS at the time wouldn't touch Ksyriums and would only offer to have Mavic rebuild them to the tune of $350.

I've since bought two SL spares for parts in an attempt keep at least one set going. Seems ridiculous but I really do like the wheels and they are, for the most part, bombproof.

I love Ksyriums but the alloy threads corrode along with any other interface. I use a penetrant soak on each nipple first along with the good advise above.

BTDT, and I still have 4 sets of Mavics.
2 sets of Kysrium Pro/Elite UST's, a set of Aksiums and the older Ksyrium Elites on Helium hubs.
The Yksion tubeless set up is "money," set and forget.

I've had several sets, including the track wheels (best made, IMO).
So here's my experience and advice.
Tools needed:
A spoke holder tool with slots to hold the spokes. No substitute.
A spoke wrench for those nipples. Get the good Mavic tool, not the free one.

Now, proceed:
1. have a spare set to ride whilst maintenance is done. install them.
2. penetrating soak, just a good drop into each nipple.
3. overnight, minimum.
(intermission: ride)
4. remove all the spokes.
5. clean each spoke and wipe down; inspect.
6. rinse the nipples in hot water, micro-Q-tip the threads and let them dry.
7. overnight, minimum, again.
(intermission: ride)
8. make sure the spokes and nipples are dry.
9. Loctite Blue or equivalent. I've heard linseed oil. Not sure about that.
10. re-assemble using Loctite on the spoke threads.
11. snug up using the spoke holder tool to keep the spoke aligned.
12. true and tension using the spoke holder tool to keep the spoke aligned.
13. overnight, minimum, again.
(intermission: ride)
14. re-true, using the spoke holder tool to keep the spoke aligned. (sense a pattern?)
15. re-install. Adjust brakes, make sure QR is tight, tires good.
16. ride.
17. pat self on back and exude smugness.

You can hardly spend as little money and feel as good about it when it's done.
The wheels will outlast your bike.

I see more "old" Mavics with 11-sp setups than any other.
One reason they're still around.
I have spare Shimano and Campagnolo freehubs for my Mavics.
You just never know when you need wheels. Mavic has vision.

If you have a shop re-do them, GIVE them the plastic spoke-holder tool. It sure beats the twisted look.
Think outside the box for your wheel builder. It's worth every cent. Give them the tools they need.

Lots of good advice.
I did get this Park SW13 spoke tool.
Searched the bay and see the spokes are selling for 10 (used) to 25 (new) each, wow, had no idea and should have posted after crumbling one of them.

Oof. Maybe a local shop or co-op could harvest some spokes from some trashed wheels. I am glad the Speedcities I have on my Lemond Poprad have regular round straight pull spokes. They still have those funky nipples (snicker) though.

Had the same problem trying to replace a spoke on an SSC, whilst using the correct tools. PITA.

Most of the Mavics I see have a round spoke or two....
