So I was out on a ride this mornign with my fiance and a friend. Beautiful morning.... the ride was going great. We went fdown a fairly steep hill, and then started sprinting up the next one. About 3 pedal strokes out of the saddle I hear a lound *BANG* and I just about lost control of the bike. I thought I'd threw the chain.... but in fact THIS is what happened:

Needless to say.... not good! We were a few miles from the end of our ride too.... so I had to start hoofin it, while Robin rode home to get the car. My "get some miles in before work ride" turned out to be a little longer than initially expected :) Now I have to wait on Time to send a new one... ugh..... But, at least I didn't get hurt. I'm thankful this didn't happen in a race. That could have been messy. I'm still not really sure how I managed to keep the bike upright when it let go.... Maybe that MTB riding I've been doing has paid off a little :)

That's an amazing failure.

I'm getting less convinced about the suitability of carbon for all bike parts.

It was crazy... all 5 just went at once.... *BANG*! No creaking before hand or anything. They were abotu 2 months old. I'm considering selling the new ones when they come in, and getting some Campy Record 07 cranks instead. After seeing the Chorus 07 cranks that I put on my fiance's bike.... I can't imaging they woudl EVER fail like this.

Well we have seen several Stronglight Pulsions fail in nearly the exact same manner. The same company manufactures the Time cranks FWIW.

I know... I've seen those same pics. I was hoping I'd have better luck I guess! I am not overly heavy, at 175 lbs. The cranks were not old either and I take very good care of my gear. Stuff just happens sometimes.... I guess.

Its a shame to see this but once again this is a stronglight made product, there seems to be a few instances of failure from them recently, Im glad you were ok and you are getting a replacement, hopefully it wont take too long to get sorted out. I have also been thinking aout selling my pulsions and going for some record cranks, i love the pulsions but they seem to fragile.

I've got a stronglight pulsion laying on my desk with exactly the same damage......
I'm getting more and more convinced (third failing crankset in a short period) that the stronglight carbon products are unsafe and just not worth the money (stopped selling it some time ago.....)

I must say that I still think carbon is totally unnecessary for cranks. Aluminum is much more appropriate in my mind. I know I am in a minority though.

It's a great place to save weight but it comes at a price.

Wow! Do you have pictures of the legs that did that damage :lol: . Actually glad to hear you didn't go down or get hurt! I wouldn't go so far as to say carbon is a bad crank material...until mine fail :wink: ... I think anything can be engineered properly to withstand a certain amout of stress. Good luck with getting your new cranks in a timely manner! May be worth buying a different set now & selling those when they arrive. Don't know what I'd do with a downed bike :cry:

But I would say the spider should have alloy tabs.

Wow!

Yeah, I too would be very wary of full carbon tabs. Does anyone know if the 07 Record cranks have full carbon tabs?

Glad you are unhurt.
