About a dozen cracks in my rear Ksyrium rim(7 posts)

About a dozen cracks in my rear Ksyrium rimQuentinCassidy

My rear Ksyrium was going out of true pretty rapidly, and I figured a spoke was about to break.

Upon checking the rim, I see just about every other hole in the rim has a hairline fracture emanating parallel the the rim. The cracks are all less than 2cm, except for the one that was causing the wheel to come untrue. That was was about 3 cm in either direction, and the crack had opened up to the point that you could see it from a couple of yards away.

This is a new one to me... anybody else ever hear of it? I weigh around 175 and had put less than 1500mi on the wheels.
This is how rims normally fail..MR_GRUMPY

Pretty soon, the spoke will pull through. Mavic might cover it, but I doubt it. Time to have a new rim laced on your old spokes.
Your shop should be able to send in your wheel to have it repaired.
cm or mm?- nmfiltersweep

Absent some sort of abuse (hard to imagine what it could have been!) these rims should never have failed this rapidly. Even 15 thousand miles would be a surprise, but 1500 is absurd. It would be hard to imagine how they could not be covered by warrantee.
Check the warranty......roadmeister

I had a pair of Shimano Dura-Ace WH7700 wheels with cracks around the spoke eyelets after almost 2 years and 6,000 miles, and my LBS sent them back to Shimano. I received in return a brand-new pair of 2002 WH-7701 wheels at absolutely no charge. I was VERY surprised, as I figured my $900 investment was history...hopefully Mavic's customer service is as good. Return them & see what happens...
My friend and I both have K's, and haven't seen this problem.Paul

Have seen it on Open pros. My friend broke a rear spoke on a new pair. He has about 17,000 miles on the other pair with no problem. sounds like yours was overtensioned at the factory. This is a problem with any hi-tensioned wheel, you can crack the rim if you're not careful.

Sounds like it is still under warrenty.
