Last Saturday I rode IM Vitoria bike course in preparation for the race (whenever it will be, but that is another story…). I had a brand new Zipp super 9 sitting around waiting for a race to finally happen, so I thought it would be a good idea to give it a try. I setup the wheel tubeless and threw in a 11-28, and was good to go.
I uneventfully rode 135k, and when I came off the bike I found this damage in the disc (see images).
No impact or rub signal, just this carbon failure, looks to me that it is a wheel defect. I contacted the seller and I am now waiting for a reply from Zipp’s rep.
I have no experience with wheel failure, and wonder if the disc is now safe to ride (I’d say it is not). Has any of you seen this happen before? what could be the cause? Do you think it is safe to ride?
In case you are wondering, I am 79kg, ¿174 lbs?, so well within the weight limits
Gotcha. Again, so sorry to hear about it. I have had many Zipp wheels and never anything like that. I too have a new Super 9 . . . haven’t had the opportunity to use it much yet.
I was not aware of any impact during the ride (I know I could be wrong), and impacts this strong tend to leave a mark…
If you look at this pic, the damage seems limited to a particular carbon layer, it suddenly stops where the new layer begins (see the different tone) I’d say that this is not typical of an impact, looks more as a result of stress, and probably due to a faulty carbon layer?
I will not be riding the wheel until Zipp tells me it is safe to ride.
Yes, I have owned several Zipp wheelsets myself, and this is the first problem I have. I hope their warranty service lives up to the quality of their stuff.
I crashed and mine has way worse damage than that, but I just ride anyway with no problems. Damage is close to the hub though. I’m pretty light, so I don’t give a crap. I have another new Super 9 disc sitting in my closet, so if this one gives out, I will switch to that one.

As a general rule, and simplifying a bit - closer to the hub may well weaken the wheel more and make a sudden catastrophic failure more likely since stresses are more concentrated closer to the hub.
It’s not running out of wheels I’d be worried about, it’s having a wheel fail under me. Your attitude is pretty reckless IMO, at least as communicated.

How dumb are some people??? Who rides a wheel with crash damage?? Could kill himself or worse a fellow competitor with a high speed wheel failure.
Agree 100%. No way I’'l be riding this wheel again.I have had a serious crash before (not failure related, I was hit by a car while training) and I’d rather throw away the wheel than go through that again.
