Well I busted an SL Crank this weekend. It's on a 2007 Carbon Rush which I bought pretty much new in December. I have the unregistered warrenty card, but it is a 3 year old bike and I am not the original owner, so I'm assuming that the warrenty isn't going to apply to me. Anyone think any different?

OK, now what? I guess I'm in the market for a new crank. Now I understand the "Light, Durable or Cheap" scenario and defintely want to go Light and Durable. I don't want to go 10spd and I want to keep both the triple rings and the BB30.

There are a couple Hollowgrams on Ebay, but definitely not "Cheap"! The other alternatives I'm looking at are these two options;

Truvativ BB30 X.O 3.3... These run about $400 and change, but they are a bit on the heavy side. They are 10spd but the 64/104BCD means I can change out the rings for the FSA ones from the busted SL.

E-Bones W BB30... for about $550 minus the rings and these are light! Again, I can just use my FSA 64/104 BCD Rings.

Are there any other options I'm missing (and no, I don't think FSA is in the running)? Any experience between these two? What would you do?

There was an official recall on the FSA manufactured carbon bb30 cranks if I remember correctly....
So, even if you're not the original owner you might have a chance to get something settled through your dealer....the cannondale warranty pertains only to the frame anyways.
Did you contact FSA customer service yet?

No, should I contact FSA or Cannondale? And seriously, the guy I bought this bike from never rode it. It had maybe 50 miles of road and parking lot on it. It still had the original tires and stickers on it. So even though it was three years old, it was clean as new! I've maybe put 200 on it in the last 3 months. So this isn't a "wear and tear" issue.

I would try FSA first and see what they say....most manufacturers of high end parts are pretty supportive after one of their products had a failure.....

What about replacing with the same cranks?
I thought about that too, but those are 170's and I'm 6'0" tall and definitely want a 175 crank arm. Plus, I'm a little gun shy now of the FSA Cranks.

I did find a better deal on the Extralite's here. Anyone riding them and care to comment on the stiffness? I'm liking the idea of a light alloy crank. I'm wondering if they are similar to the Shimano XTR's in feel?

It's also why I would consider some Hollowgrams...

Pro riders have often stated that they don't notice the difference between 170 and 175 crank arms, so its unlikely you will.

Your failure might be apart of the 2007 recall on the Si cranks (most likely, as these cranks have a good reputation), so it would be worth letting FSA or Cannondale know about it, even just to see what they say.

You can find the recall info on this page. Go down to "Recalls", and download the corresponding PDF.

Thanks!!! I will send this off to FSA and see what they have to say. :thumbsup:

The X.0 BB30 double is 710g w/ BB, lighter than the Si (730 I think). The triple can't be too much more.
I thought Cannondale said on their site (before they changed it and hid everything) "At a total system weight of 580 grams, the Hollowgram Si SL and BB30 system..."

As for a triple, I missed that. Sorry. It's a shame you want so much weight savings. I am taking off my Truvativ AKA triple BB30 (came on my 2011 Jekyll) and am selling it ASAP. I am replacing it with a XX setup. It weighs 800g with a BB30. and is certainly strong enough. It would be cheap too. Oh well.

Good luck!

I think I saw 630gr for the Hollowgram with a triple somewhere. It is one of the lighter cranks out there and would work well. But it's pulling $700 on Ebay. The Extralite can be had for $470 so it's looking like the way to go.

Course I want to see what FSA has to say, but time is short in that I have a race on April 9th and have to get sorted before then.

And thanks Hunter, do appreciate the thought, but considering you are going to an XX, I think we both appreciate saving weight where ever possible! :thumbsup:

Sorry I'm a little confused here. You stated that you busted an SL crank. Was it an SL hollowgram or the FSA SI carbon? The SL is made by Cannondale. If it's an SL crank, you can just replace whatever broke (crank arm or spider). Otherwise, the FSA Afterburner is a reasonably priced alternative albeit a little heavier than the more expensive options. The aluminum SI cranks are only 50g heavier than the SL's and you can usually find one on ebay at a reasonable price.

I've got the Extralights. I could tell the difference in stiffness compared to the SL's now on that bike, but mostly in ride quality, as in the the Extralights were a bit easier on my feet after 24 hours. I am sure there is a difference in power transfer as well, but I couldn't quantify that. They are different systems though, the Extralights are an external bearing like deal and I had to green loctite the bearing cup into the BB 30 shell to keep them from creaking. Very narrow Q- factor as well so factor that in.

I'm 150 pounds and they now reside on my wife's bike and have been problem free so far.

Your problem is really simple, you have to change the spindle, is cheaper than a crank set. That way you will keep tha carbon cranks. The recall for the cranks is a problem whit the crabon estructure.

You can change the spindle? I thought it was bonded to the drive side crank? I'll have to look at it when I get home. And yes, my bad, these are the "Si" FSA Cranks, not the Hollowgrams.
