Mavic Open 4 CD Rims

Have you any experience with these rims?

Check out the thread titled "Mavic rims don't *all* suck" for the local
opinion of the O4CD. I posted several pictures of one such rim that
failed after many kmiles. Some of the locals think that wasn't enough;
the rim should have lasted until the braking surface was thinner.

My opinion? If everything I owned gave me the same durability, I'd be
happy. I just wish the failed rims had given me some warning before
failing, but I don't know if that's possible.

SNIP!

I've never owned a pair of O4CDs, but I certainly sold a few...

IIRC, the biggest differences between the O4CD and the Reflex/Open Pro
rims
are no machined sidewall, and no welded seam.

No matter WHAT people say about Mavic rims, you should get lots of good
mileage out of these. Keep checking for cracks every once in a while
(like
you should with everything else) and ride the heck out of them!

That help?

Thanks to Mike and the rest for their replies.

Seems the Mavic Open 4 CD has a good reputation and history. I'll
pick them up.

Wayne

Make sure that you're getting a screaming deal. These guys have been out of
production for a while now...

That all depends on to whom you listen... Some think the sun rises and sets
on Mavic's HQ, some think they're the worst thing to happen since the
Hindenburg...

I'm in the center, leaning more toward the former vs. the latter.

Some people might consider a rim cracking at the spoke holes to be a
warning. I think it's probably safer than a side wall letting the tire
off without warning.

Especially since the Open4 CD has a two-piece, double wall spoke
"socket," and when the rim cracks around the spoke hole, there is
still a lot of area left to support the socket. In fact, I
simply re-trued my rim and rode it for a few hundred more miles
until I had bottomed out the spoke, and it looked like the rim
was going to give birth to the socket. -- Jay Beattie.

I see no evidence of cracking at the spoke holes on the rim in question.
I'm not sure I understand your message.

Sorry, my post was in response to others saying rims should *never*
crack at the spoke holes, saying that would be a catastrophic failure.
I was just commenting that I'd *rather* see spoke holes crack, because
I'm afraid I'd miss the signs of an impending sidewall failure, which
would make it catastrophic for me.

I understand. And my pictures will vouch for the fact that I *did* miss
the signs of impending sidewall failure.

Seems to me that you can watch a spoke pull thru the rim, but a sidewall
blowout is more violent.

Of the two, I'd rather have my nipples pull thru.
