    Cannondale Carbon crank failure?

    Has anyone had this problem? My '06 carbon compact cannondale si crank arm came loose. not from the BB, but from the aluminum insert that bolts to the crank. it would wiggle like it was loose on the BB, but when we checked the BB was fine, the interference fit was fine, couldn't see any problem. THen we put a wrench on the crank arm off the bike and could actually see the aluminum fitting move inside the carbon arm. The LBS had another off a warranty bike and checked it.. same problem. that's what it was warranteed for. bike is tecnically out of warranty but i think my lbs will get it done for me. just checking to see if anyone else has had this problem. Design changed in '07 and got recalled on that one, so mine may be a bit of an orphan.

    No one?
    Just got a call from my LBS. Seems Cannondale is aware of the problem, but since it was a design flaw from FSA, the design was changed and there are no more replacements. The only alternative is to replace the entire crank with a '07 on design. Of course since it's been a year, Cannondale doesn't think it's a warranty issue, so all my LBS can do is sell me a new crank at cost. he's trying, but Cannondale isn't helping much. Has anyone had this problem with a good outcome?

    There was a recall last year on all Cannondale SI cranks. Someone is not giving you the right story.

    Edit:

    Here's the link for the recall:

    This does not include the '06 cranks, but I would want to have Cannondale convince me that it's not the same problem.

    It was a redesign. the '07 design recall cranks aren't compatible with mine. They have a hollow crank spindle which had some heat treatment issues and has been known to crack and fail catastrophically. Since mine is known to fail but not actually in a way that hurts anyone it seems like they decided not to recall it. they just changed the design to the new one. lot of good that did them or does for me. Hopefully my lbs can get them to warranty me an '08 crank and i'll be ok. otherwise if i have to buy my own, it will be a chorus. now that's some $$ i didn't want to spend!

    hopefully you will get the warranty, so you don't have to go away from the BB30 and use an adapter to mount the chorus crank.

    Here's some Campy_food_for_thought for you. I just priced a new set of Campy chainring bolts, spacers, and nuts for a customer. Cost to customer would have been $140(!!!). That's no kidding. The high end Campy stuff is getting ridiculously out of range. Yes, you can get all of the pieces parts for Campy stuff, but be prepared to pay a VERY high price to replace them. If you think the grouppo costs a lot, wait until you need some repairs.
