    Broken Scalpel carbon 29's

    Is anyone else seeing consistent reliability issues with this frame?

    I have broken 2 frames (in about 2 months), and I have two friends that have each broken one. Just curious if we got a bad batch or if this was being experienced elsewhere.

    Could be user error?
    If a batch was that bad somebody somewhere would speak about it. No offense, but threads like this reminds me of the youtube clip of a guy hopping down staircases.

    Possibly, however, I am about 175lbs at most, and ride/race only xc in Texas. Bikes have never been crashed, I have raced bikes the better part of my life and like to think I am a smooth rider.

    I broke 4 in 4 months and my boy broke 2 in 2 days, each frame failure occurred while our grandmothers were riding the bikes to get groceries and lottery tix.

    Been a good strong frame otherwise, though.

    No, neither frame has touched the ground. My friends haven't either. Cannondale has been good about the warranty, I am just concerned I am going to have a bike that won't last the whole race season.

    As we all know, ANY frame can be broken - no matter how sound the design and execution - this is especially true of a race XC frame. So simply stating that frames have failed is almost meaningless, except for trolling purposes.

    Usually, folks interested in setting up a thread for product failure data collection - begin by providing pics and details of how the frame(s) failed, how c'dale handled it, etc. etc.


    Do you care to tell us what happenned?

    The bike is flat out amazing, stiff, responsive, light, holds speed well etc. hence my disappointment. Cannondale is good about the warranty, it is however frustrating having to wait for parts to be in stock.

    The first one (second pic) I noticed while I was cleaning my bike after a fairly casual 25 mile ride here in Texas. No drops, jumps, etc. Just what I would call typical Texas hill country technical xc.

    The second one failed while I was riding, I came up a small rocky climb and almost got pitched over the bars. I got off and walked up the rest of the climb, hopped on again and the bike lurched rearward again. Upon closer inspection the wheel was contacting the frame when pressure was applied to the pedals. I found the break and got to walk about 8 miles home.

    Well, considering people are jumping, rock gardening, etc with these frames, I have to imagine that your failures are due to defects unique to your frames, ie isolated instances of poor QC.

    i have no pics , however a friend here in Italy had a failure.

    probably caused from cable guides in the bottom of the main tube .

    they are too rigid, too much force applied from cables and hoses and it causes a break starting from the screw hole.

    this is my friend theory, waiting for a reply from Cannondale.

    i have no opinion about it ... i never had a Scalpel 29er

    That's why I thought as well.....the way it's frayed it sure looks like a lot of force caused this frame to fail and judging by the overall look it seems the bike didn't get a lot of love either....probably a Rental/Fleet bike?

    I also notice in the first pic there is a mark on the cable housing under the break that looks like it may have been from something hitting it.

    Not really sure what you are talking about, i race marathon, xc, and a few short track races, bike is very well maintained, I have worked in shops for 15 years. The bike has maybe 750 miles/ 30 rides on it.

    One of my buddies had the rear brake mounting tab debond itself on his '12 29er Carbon 1 - 4th ride (this was back in July). Cannondale sent a new rear triangle out, no questions. No issues since then.

    he's also had the rear hub come apart - the section of hub where the rotor mounts, started rotating on the hub body some. DT replaced the wheel once - it just happened again last week - I don't know if he had time to talk to them again yet.

    Still awaiting a swing arm. Cannondale now is going to send a mismatching swing arm once they are available. I am extremely disappointed, I even offered to take a Jekyll replacement frame that would be stronger and they offered it to me for a $1000 fee. Buyer beware.

    If I am correct, these bikes are the ones with no bottom hinges and the two bottom tubes flex. I was wondering how these would hold up. I saw a youtube vid on this and was unsure about the setup. Seeing the first pix confirmed my thought about its strength. When you are flexing the bottom of the rear box with no pivots you will weaken the carbon. Oh well, nice try Cannondale.

    29er has a pivot. 26 does not.

    Nope, only the alloy 29'er has hinges, the 29'er carbon has none just like the 26'er.

    EDIT: My appologies , for some reason I thought we are talking about the main pivot.

    The 29er carbon does indeed have a pivot behind the BB, unlike the 26er which does not.

    The 29er aluminum has an additional pivot above the dropout on the seat stay, which the carbon does NOT have.

    You guys are all right, kind of. Excluding the shock swing link...

    29er Carbon: 1 pivot at the chainstay, bottom bracket junction
    29er Alloy: 2 pivots, one at the seatstay, bb junction, another at the Chainstay/seatstay junction.
    26er (carbon only): No pivots

    When CSG offered me a mismatched frame, I rejected it and told them to replace the whole bike and they did.

    Don't accept a mismatching swing arm, that will look awful. I highly doubt Cannondale want you riding it around, basically advertising the fact that they've had a failiure. They should at the very least, replace the WHOLE frame. Can I ask, when did you buy the bike?

    In regards to the "trolling". Guys, give him a break. Don't get me wrong it did initially look like he was trolling but not everyone is very good at expressing themselves on a public forum. Especailly when this sort of thing happens.

    The bottom line is, ANY frame can be broken. You just have to be unlucky. I mean look at that guy's Jeckyll in one of the other threads. All because he was using the wrong seatpost clamp, he wasn't to know. An easy mistake to make, with a brutal punishment. I know how it feels to be in this position (mine was a manufacturing fault luckily), so let's offer some support here.
    and no, I am not missing the other half of my fork....

    I ended up buying a different frame. I can't risk having to miss races due to more frame failures. If anyone wants a scalpel 1 xl frame let me know.

    I have put many rough miles on mine. NO issues what so ever. I just got a Trigger 29er since I have been pushing Scalpel "beyond" its intended use.

    Broken Scalpel carbon 29's-broken-scalpel.jpgThread resurrection.

    I received my Scalpel 29 Carbon 2 in August 2012 - It's an amazing bike.

    Whilst training last week I've suffered a frame failure at the drive side chainstay - broken right through.

    I can't imagine that I broke the bike that ride, perhaps there was a crack already I hadnt noticed where the frame had been covered by a chainstay protector... I don't know.

    Regardless - Cannondale will not honor the warranty on this break - it does look pretty similar to the failure posted by SuperSlow though.

    That it's a 'single catastrophic failure'.

    So I believe they think I've crashed it hard, or been downhilling on it - neither true.

    I've been offered a discounted rear swingarm, and my LBS (who are awesome) have offered to swap this over for free as a gesture.

    Such a shame.

    It was 225 GBP, so came in a lot cheaper than I had expected.

    Took around 3 weeks for the part to arrive as there were non available in Europe.

    LBS did all the work for free as per above post.

    Super please to have the bike back!

    The reason there is a "thread resurrection" is that people like me search google when their frames break in shocking ways. My 2013 scalpel 1 broke in the seat tube area after 270 miles. I weigh 153 lbs and just ride normal flattish XC type trails. Yay the warranty is great but This is the 4th warranty and I'm without a bike for A month or so each time. I tip the bike shop guys like crazy too. My last chainstay area break looked a lot like yours just not quite as knarly. It started as a small looking stress crack that got worse and worse each ride until I could tell it would break soon. The authorized dealer suggested I ride it til it broke. I realized if I did that it WOULD end up looking like a crash or bike rack fall off. I'm lucky they've not cried "catastrophic event".

    A friend of mine has the same problem, the back swimg arm on his scalpel carbon 2 broke last september 2013 and he's still waiting for a replacement, i think thats so ridiculous. I my self have a cannondale f29 aluminum and i too afraid to buy a carbon frame from them.

    If any of you can help us whit this matter we would greatly appreciate it.

    2013 Cannondale Scalpel Carbon 29er part

    Hi there. Sorry to reply to an old thread but i'm looking for a very random Scalpel part. I have uploaded a picture of the part I'm looking for. Hopefully someone has one laying around that I can purchase. Do you have a damaged rear triangle and might have one laying around.
    Thanks in advance.Broken Scalpel carbon 29's-scalpel29er-carbon_part.jpg
