Yes, Virginia, Dura Ace cranks can indeed snap.
Ow......Sucker snapped right in the middle. Out of warranty, my 7800 non-drive side crank arm decided to snap when I was slowly accelerating out of the saddle, on a solo training ride. I was in pain, so I had to walk 3/4 mile home. Drove to the ER, where they discovered three broken ribs. (but just a sore collarbone)….Chugging down Valium to help the pain...…..Before I went to the ER, I jumped on eBay and found a matching 7800 arm for only $38.50......Score one for me...…..Looks like this is going to set me back quite a bit. I'll be lucky to be able to get back on the bike in two weeks, and four for real training...….bummer.
If your opinion differs from mine, ..........Too bad.

Buying parts to hang on your bike is always easier than getting fit.
If you feel wimpy and weak, get out and train more, ya wee lassie!

Sorry to hear that, Grumpy. Rest up and relish in the badassness of putting enough power and torque into a crankarm to snap it in two.

Chugging Valium because of the pain. But you had no problem with the pain while searching for parts. Damn that is a true cyclist! Hope you heal fast.

First things first......I couldn't let that deal slip away...…$38.50 Buy It Now price. If I didn't get that one, the only other 175mm arm is going for $102.99 Buy it now price, with $7.50 shipping.....(The one I bought had free shipping)

OUCH!!! WTF kind of power and weight do you have that can snap a crank arm? You're lucky the broken edge of the crank arm didn't impale your leg!
Rest up and get better soon!

This could have been REALLY bad in a field sprint.
I've been moving rather slow today, but here's some photos...…..

Moving slow is understandable.

That is a surprising spot for it to break.

Which makes me wonder..., MR_GRUMPY, did you have an argument with someone recently and left your bike unattended for a while? Emoticon-Think.gif

I dont think you should warranty this. Right now you have an awesome story: you snapped a crank in half, very Badass. Now if the story goes that the crank was replaced as defective, that is not as impressive. A good story is worth $38

You must spread some Reputation around before giving it to DaveG again.

Maybe so.....To make a story about how I rode over a fallen rider's hand in the final turn of a criterium better. I change it to hopping over his entire body. Like something Peter Sagan would do. As long as you only "modify" a story slightly, it's fair.
In this case, I don't have to mention that at most, I was only putting 250W into the crank.

Glad you got away with as little injury as you did, MR_GRUMP.

I would still send the crack arm out to a Dura-Ace rep for examination. Their RGA department keep track of stuff like that.
