There's bad Chinese carbon, and good Chinese carbon.

 

Non Chinese carbon isn't garanteed not to break either.

 

Your rims are clearly very *** productions, which, let's face it, could have happened from "branded" rims too.

 

Take them back, demand exchange or refund. Don't let this experience scare you away from non branded stuff, you just got unlucky with these.

 

I'm 100 kgs on a good day and my wheels are Chinese, just like my road frame. They've both stood up brilliantly to the forced applied, including massive rumble strips hit at proper speed, me jumping the bike over road cracks and bridge expansion joints, and all is well. Would recommend you pop past summit cycles and have anton check out your next set, the man is brilliant and knows his stuff. He also doesn't turn his nose up at Chinese parts, and is more than happy to work on them, unlike a certain shop in bedfordview...

Shoo, tell us more !

 

There isn't much more to tell.  He showed me the failed Enve rim.  It was clearly a manufacturing defect.  The failed part was as thin as paper.

 

Enve ,paper thin ?

Have you actually held an unbuilt Enve rim in your hand ever ?

It takes a wheel builder with real skill to build a carbon rim where you can't see the nipples.

Don't blame the "wheel builders" lack of skill on the product.

 

I think you actually said it well "he once tried"

 

Haha, you're funny :D  Do relax Mr Earp, I'm not saying Enve rims are rubbish. Doing so, based on a single incident involving Enve, would be almost as illogical as saying all Chinese carbon rims are rubbish based on a single incident involving a Taiwanese rim!

Nope that's not how it works, 1 out of hundreds or thousands of Chinese/Japanese/Taiwanese fails and its all rubbish and cheaply made.

 

1 out of hundreds or thousands of (insert name brand here) fails and it's a manufacturing defect.

 

There are 2 issues here, 1 the failed rim. So it's unbranded then we shouldn't be surprised. The LBS question, needs to sort whatever the OP deems incorrect/false that's another issue.

When people have no facts they become petty and fall to the "you funny guy" game.

I have seen that rim myself, poor workmanship by an unqualified wheel builder .

Oh, you mean you weren't joking?  Interesting.  My apologies then - you are not a funny guy.  

When people disagree with you they automatically "have no facts"?  I held that rim in my hands, examined the shattered bits standing up from the rim and could see quite clearly with my own eyes how thin the affected area was. That does not count as fact?  If the rim you saw wasn't paper thin in places, perhaps it was a different one?

 

Regardless of what the issue may have been with the Enve rim/s (?), it doesn't change the fact that even the most well-regarded manufacturers produce a dud now and then.  Someone else commented in this thread that a failure such as reported by the OP would never have happened with a name brand product.  One simply cannot say that for sure. 

 

Stressed Eric, I hope your LBS makes this right and, like DragoRosso said, don't let this bad experience put you off all Chinese rims.

Actually I held the entire wheelset in my hands ,the front wheel was an egg, the rear wheel where the nipples pulled through the rim was from yet again ,poor wheel building ,the spoke tension on the drive side was insanely high, so high in actual fact that even a DT ,Mavic or Stans alloy rim would have had nipples pull through the alloy, and all that because he couldn't get the dishing right because of incorrect spoke length.

Oh, and the shattered bits you saw were only the first few layers of the carbon layout .

And you didn't disagree ,you shot from the hip and got yourself in to a proper corner now.

Didn't disagree with what, Mr Earp?  I don't think we're even talking about the same rims here.  Why are you so worked up about this?  If you have some unresolved history with Johan Bornman then perhaps the two of you should talk about it?  Your opinion of him as wheelbuilder is off topic and we are cluttering up the OP's thread.  Please PM me if you really need to discuss this some more.

We have much unresolved history ,and that has nothing to do with the fact that you raised the issue in the first place, you mentioned the "fabled" Enve wheels

Did you expect it to go by unnoticed ?

And we are talking about the one and same wheel set .

If you want to talk pm. me ,I have nothing to discuss with you I am not prepared to discuss openly.

Did you mention the Enve wheels or not, and did you expect people to just suck it up ?

:lol:  Why not ask Johan Bornman about that?  He once tried to build up a set of new Enves, but a spoke pulled right through a part where the carbon was paper-thin.  

Just a remainder in case you forgot.

And no, the carbon was not paper thin.

Oh my!  :lol:   May I point out my join date: 16 August 2014.  To think that every person on these forums knows about your shared history or any "fabled" wheel sets is a just tad egocentric.  So, you can rest assured that I did not expect you to not notice anything.  I have no idea what you mean by having to "suck it up".  For some reason you seem to think that I am trying to rile you up.  I find it very strange that you are obviously very angry and feel that it is important to argue this issue when the only take-home message is that any branded or non-branded rims can fail.  Fine, so you object to the example I gave.  Whatever, man.  Google "Enve fail" for other examples if you prefer.  Seriously!

Because you are a newbie - I will let you down gently.

 

Lesson 1 - don't poke the bear.... unless you have great backup.

Lesson 2 - The sheriff is the sheriff for a reason... and some of us know him personally - if he says the facts are A, then the facts are A - he is not capable of not being a straight shooter.... (I am not sure if this is a personality strength or a personality flaw - but I don't complain about it)

Lesson 3 - The man can build wheels... and stands by his product.

 

Lesson 4 - read the thread on JB's 91 page book on chains... you might get the idea after that of his general capability and the level of respect people have for him.

Lesson 5 - if you want to understand something - talk to the man - pm him and ask for a number..

Number 4 - do you perchance have a link? I feel like having a bit of a chuckle...
