Limitations of Cobras (carbon fiber)?

Here and there I've heard allusions to the fact that Cobras are fragile due to their carbon fiber composition.

Is this a real limitation? Are there former Cobra owners out there who have tapped on a piton only to find their Cobra blow away as a cloud of dust? Did some unlucky bloke pull a mixed move only to have the shaft cave like a dried husk?

Or is this a comfortable way of removing an expensive object of desire from the selection pool?

Everything can brake- especially if one tries REALLY hard Wink
Never herd of broken carbon tool. Have herd of broken aluminum dough Frown. Carbon tools are on the market for a long time so even if there was a problem, it would have been fixed long time ago.
Never used carbon tool, but from what I've head the shaft can be really slippery when is wet, or there's some snow on it.

So i guess it would boil down to the standart issues:
carbon breaks, whereas alumium bends.

So something that might put a dent in a aluminium tool, puts a hole in a crabon tool. But i dont know, i am just roughly extrapolating from other carbon vs aluminum things (ie bikes).

Look how far down the shaft there is metal



I wouldn't worry about bashing them apart unless it's some pretty weird and sharp dry tooling. In which case the only thing that would hold would be a monster anyway.

I had a similar concern and when I visited the BD factory in Salt Lake, I asked the QA guys. Their answer was that, while freak accidents can of course happen, the forces you need to break the shaft of a cobra were very unlikely to be encountered in real world uses. And perhaps more convincing, they had a test where they banged the shaft on a concrete step a hundred times (to simulate missing while trying to hammer a piton in) and though it looked bruised, the tool was still intact and fully functional.

That's enough to dispel a lot of misconceptions right there.

First generation of the first generation heads broke off. But first generation *anything* from BD can be expected to break--consumer product testing at its finest. They fixed the problem and later models of the first generation held up fine. Haven't heard of any issues with the second generation regarding durability. Performance and versatility took a real hit but who cares when they look marvelous--it's all about style and marketing!

Guys, I've heard of no reports of the original Cobras breaking. The new versions have only been out one season but I've not heard of any problems with those either.

Slipper shafts can be resolved with grip tape or Bulldog tape.

Smashing the shaft against rock or pins can be solved by swing training.

that is awful info!
both materials can crack or break. if you took a carbon tool vs. an aluminium tool with a similar gouge in the material my money would be on the carbon tool any day.

a carbon bike (high end manufacture) is way stronger than aluminum, especially after some damage.

I guess it depends on the thickness. Its my impression that at the same thinness carbon breaks more easy than aluminium. However since i don not know how thick (or thin) the cobras or vipers are, this is hard to say wether it is a valid point or not.
