    Default Stronglight Pulsion Failure

    What a close call this weekend. I hit a rough patch of road and the next thing I notice as I stand up to sprint is that my non-drive-side crank slips forward so that it's parallel with the drive side. What happened is that the splined BB interface rounded out over the carbon structure. The interface is still bonded to the crankarm but it it spins freely since bonded area has been rounded out. The gaps you see between the carbon and the metal did not exist prior to the failure.

    I shot Stronglight USA an email. Any guesses as to what they will do for me?

    I ordered Chorus 11 as a replacement - I think I will avoid Stronglights going forward. There are some reports of broken Stronglights which I thought have been addressed with a new carbon layup, but this is the first issue of it's kind.

    12 miles of one-legged drills back home.

    It looks like Stronglight will cover this under warranty. They asked me to send the cranks back to France.

    People may flame me for saying this, but my impression is that Stronglight (misnomer) cranks are not the most robust and I would avoid them. Oh, and they should pay for shipping to France ...

    At least they're taking it back. When I broke the spider on a Campy crankset two years ago they insisted that it was user error.

    lend a little bit of perspective please?

    what's common practice?

    (1) I send Stronglight everything - rings, bb and etc and they send me new everything.
    (2) I send only the cranks and they provide new cranks.

    I ask because I've been pawned off to the French liason by Stronglight USA and communication is spotty - they said I should simply send "send them back with receipt."

    The relunctance on my part is that I just bought new BB bearings and rings for my cranks and I don't really want to part with them if it's common practice for them to send me a whole new package.

    i used to bust cranks allot. i could run 28* mtb wheels fine, but i had it out for cranks! that said - just send back the arms. strip everything else. they don't want your used stuff. there HAS to be someone there that can speak english. ask the USA rep who they deal with. i *just* sent an entire schlump BB/cranks back for repair & everyone there was VERY helpful. i did pay for everything - it wasn't their fault i sucked up an aspen stick & busted the shift button off. Shimano sent me an entire XTR setup once {everything!} when i returned just the cracked arms. work it, man! Steve.

    step 1
    send them back
    step 2
    chuck them on ebay when you get them next year ( keep shipping info )
    step 3
    get real cranks from a legit company that will back their product where its sold
    ( and probably the cranks will not break as well )

    I'll bet that Stronglight will take care of you...but it will probably take some time. I talked to one of the Bouygues Telecom mechanics at the Tour of California last year about some Pulsion failures...they used to use those cranks. I was interested as I have two pairs myself. His response was that they hadn't had an unusual number of failures...and that they had more in the years before when they had FSA....There are plenty of failures around for these cranks, though...and I always assume that where there is smoke there is fire....

    Another problem: Looks like they left out the letter "U" after the "S" in the model number SCK22-B-172.5.

    ps
    its probably obvious but dont send the chainrings
    you have a 50% chance of ever seeing the arms again.
    at least you have some rings to give somebody who needs tham.

    if you get them back
    i pick january 11th, 2010 as the return date.

    closest to the pin.

    bet payable in empty deposit bottles from darren
    estimated value $2,588.
    by then $13,433.85+/- $.25

    Cool Re: Stronglight Pulsion Failure

    Okay...I am now a victim of Stronglight. While riding this morning with Group Peleton here in Southern California , my Stronglight Helion chainrings literally "Sheered" right off the crankset. Thankfully I wasnt out of my saddle or sprinting and on a straightaway. After getting home, I search on the internet to see if the FREAKISH incident was common and low and behold Planet X of the UK issued a recall on all Stronglight Helion cranksets sold for this same exact reason. Okay...now what to do??? I purchased here in the US from Randall Scott out of Boulder CO less than a year ago and I thankfully still have my online receipt. Does anyone know who I can contact or who to send these cranks to for warranty repair or replacment? What is the warranty on these cranksets anyway? Please tell me at least a year for I would hate to think that I am out $700 for purchasing what now seems to be a "CHITTY" crankset.

    If anyone can please advise as to whom to contact, phone number or email address...I would totally appreciate.

    Regards,
    David

    Someone mentioned in the past that Stronglight was neither strong nor light. I guess this might be true.
