When carbon goes bad....

Well my rear carbon rim just delaminated




Was on a high speed loam corner with 35PSI in a 2.4 nobby nic tyre. Just heard a loud crack then the hiss of it deflating.
Sealant was coming out from between the carbon weave, and won't hold tubeless presure anymore .
Just finding out what the process for the warranty is at the mo.

They were going oh so well too!
Just finding out the deal with a warranty replacement at the moment.

Ouch. Where did the rims come from?

thanks for putting this up buddy I wont faff with Carbon for sure now 

They came from www.light-bicycle.com
They've been running really really well for the past 6months, so will see what happens.
Personally I was more surprised that it was just on a loose flat corner!
I've ridden way worse on them without a hint of trouble.

Depending on what the response on warranty is I might end up doing a pressurised epoxy repair on them.

I would it is a design flaw in the way the two halves are joined with not enough fibres/epoxy in the void, would have though a repair wouldn't be of much use unless you would fill the void between the two halves the whole way round the rim.

Think I will stick to strong-bicycle.com

Were they at least cheap?

Ive sent off my sample set of these rims to Bath uni to do some independant testing against a range of rims. As soon as the results come back ill publish them.

If its anything like the XC rim comparison we did against a cheap chinese rim its not surprising they broke from the way the XC rims were constructed.

They look fine on the outside but thats just a cosmetic layer, inside all sorts of nastys may lurk.

What im interested in is if they actually do anything about fixing the problem...

When you look at it carefully it's along the crossover in the weave (as in directly along it).
It's only an issue for about 3inches along the rim where the weave is going parallel with the rim.
If I did a repair it deffinately wouldn't be taken out in anger again.

So far they've not responded to me about the warranty....
(even though they were happy to email me straight away when i registered interest in a purchase )
BUT.... i'm in an online chat with them on the website now 
When "connecting" with your customers backfires!

Well good news..
They're sending a warranty replacement out.
Have to pay the shipping cost, but I'm not too fussed about that.
