What was the location of the failure? The same as the crank arm of the OP? Got pix? I'm just curious if @maquisard's case is isolated, which it probably isn't.ohhyeok90 wrote:I heard friend of mine who has same crank model got broked.

Looking at the original post, i'm amazed at the combination of how the fracture face looked and the lack of any mention of creaking.
it's actually possible to come to the conclusion even before realising it makes no sense at all

There's been a LOT of instances of Cannondale's SISL2 cranks cracking around the arm-spider interface area, but no complete failures. Alloy WW cranks are a little sus...
Broke a couple of ribs and in addition to the crank I have to replace my carbon bars, left Dura ace shifter and left Keo 2 Blade. Hopefully Rotor will replace the crank for me, it is with the shop. I tried contacting Rotor directly but so far they have ignored me...
I also experienced a cracked rotor 3D+ crank arm (non drive side) twice. The first one was replaced by velotech. The second time around, just 3 days ago, the 3D+ crank that came with my 2014 P5-6 and transferred to my S3 developed a crack as well in the non drive side. Same as the first, no crash and nothing out of the norm was done or happened to the crankset. Contacted rotor regarding the problem, no reply. Not sure if others here that experienced the same issue got a reply from rotor itself and if they covered the replacement.
Hi,
In the case of both my failed 3DF and 3D+ they were replaced through Velotech in the UK. On the occasion when my 3D+ failed Rotor also provided me with a set of free Q-rings as a gesture of good will.
The 3D+ is a nice crank but I would give it two season most before replacing.
What do you weigh out of interest?

Over the years I have seen failures of shimano, campag (carbon too), rotor cranks, and a few others (stronglight!) but I can't recall any sram ones. Did I just miss that or ...? I have actually toured their crank development facility in California and from what I garnered they design them to fail at the spindle (steel or AL) rather than at the carbon crank so it isn't a catastrophic one.

That's good to know! I hope they will reply to me though.
