bro going back to square taper record cranks until the '07 stuff is out. This happened without warning... no creaking... nothing.

I almost hit the deck.. luckily I dropped to the top tube and managed to stay upright by dragging both feet. I tell you... my BMX years as a wee lad are still paying off.

I was just doing some research on some other sites, and I see that there have been dozens of reported failures... spiders breaking, breaks at the BB joins, pedal threads, and even snapping right in half.

Maybe that's a little too light, and not enough strong.

Even if they replace the crank (which I assume they will) can you ever trust the replacement after that?

Hell no... once I get a replacement set... off to palooka-ville (ebay) they will go.

Good save.
Notice that the rings don't match up with the spider, sloppy workmanship.

Can I interest you in a Duprat steel crankset ?
Ride what Fausto rode, or at least 07 Centaur, in that miracle material Aluminium. Yeah, I know AL breaks too, but at least I can check it
without a major lab.

This just in......

Glad you are ok .....

Carbon :no: scares the craap outa me.

[sw3759]

holy crap Rich,i am glad you are ok.that took some real skill and a little luck to keep yourself off the pavement for sure.now tell me you are some huge dude that cranks out megawatts to have the ability to lay waste to a crank like that.
and i officially retract my question why terrytnt did not put carbon crank on his Ottrott...yikes.

[stevep]

is it strong? or light?
i forget.

[DarrenCT]

is that a scott cr1 bike? dmt flash shoes? i have the same setup :)

i was also thinking of getting that pulsion crank (until now).

From now on you will be called Robbie.................

But ouch.

Are the Times any better? Aren't they built by Stronglight?

[Kahuna]

holy crap Rich,i am glad you are ok.that took some real skill and a little luck to keep yourself off the pavement for sure.Yeah, but he didn't say how many other guys he took out! :D

Seriously, those Pulsion cranks are sketchy. Rich is right, too many others have had these things blow apart on them. I wouldn't touch them.

I am amazed to see shiite like that break.
Its like kids make the stuff and let people risk lives

I know a cat that breaks look and time pedals at
the axles on a regular basis. He looks a little like
Arnold when he won his first Mr Olympia.
