Rim/ Eyelet Stress Crack

Dug my old Ksyrium SR's out with a view to using them again for training come the Spring, but noticed small defect around one of the spoke eyelets. It's slightly raised to-the-touch, so not just surface/ paint scratch.

Safe to ride or not? I know there's a lot of tension in these designs. Seems a shame as despite their age, they're fantastic wheels...

    I've a similar thing on one of my wheels. Rode it for ages after finding it. I just keep checking on it.

    Surely I see cracks. If those are crack don't ride it the tide could be ruined and your left stuck somewhere.

  • It's for the bin...

    It's so common on Ksyrium rims, that it is almost surprising when it doesn't happen

    You could relegate it to a turbo-trainer wheel......
    FFS! Harden up and grow a pair :D

    Not long for this world but it's not going to explode without warning and impale a spoke through your chest. Just watch for the progression to other eyelets. Soon as you see it on more than 2 or 3, then time to turn it into coat hangers.
  • I had this problem years ago on a pair of Ksyrium SLs . I put them on eBay with, I hasten to add, an honest description and detailed photos of the problem. A cross racer bought them. I met up with him to exchange my wheels for his cash. He really rated Ksyriums and took the view that if he got a couple of seasons out of them then great. Can't remember what I sold them to him for but both of us were happy with the deal.

  • Interesting.

    Ironic that the pair of SRs I have have been absolutely "bomb-proof" (I know, I hate that term too). Never needed to see a trueing jig, and I'd hoped had a few years left in them.

    The ones I had were excellent to that point. I would have done somewhere between 15 to 20,000 miles on them before I noticed the crack. In the time I had them in the bike shop once when I broke a spoke. Having that conversation with the guy that bought them from me though did make me think maybe I'd been too quick to replace them but then again you need to have full confidence in your wheels.

    Cyclocross is not road cycling... the speed you reach on a mud course is never too dangerous and when you go down (which happens a lot) you land on soft ground...Moreover, you are lapping around a half a mile course, so you don't need to call a taxi to go home...
    Moral, you can afford to use them... out on the road, with speeds up to 40-50 mph... car traffic, I wouldn't bother
