    The issue is not dangerous, nor will it fail catastrophically. It is, however, pretty embarrassing. We apologize for the inconvenience it has caused our riders.

    We made a change in production as soon as the problem was identified. It is confined to less than 1% of production from last season.

    Whether or not a frame had this issue was obvious when the engineering team inspected our stock. We have removed any frames displaying this problem from our warehouse.

    If you ever have an issue with a Niner product, contact your dealer. We will stand behind our warranty.

    Hello Carla,

    Are we talking about the RDO frame or the jet carbon. I just ordered a jet carbon. Should I be worried?

    Sw the photo at the top of this thread, and died a little. Same thing on my RDO, obvious after the first weekend - ie after I washed it!

    I'm not keen at all on getting a new one, not least of all, because I fear the white might Not be available . And there are no circumstances whereby I would have bought white forks for a bike accept for the Van RDO . It's also greatly complicated by me buying the bike while in continental US.......

    Cool, I'd love to take you up on that offer. I was talking to BikeLane yesterday, and they said they had no idea when they'd have the bike back, and explained your circumstances. I was pretty amused to see your post right when I got off the phone with them. Thanks!

    My lower shock bolt and another 2012 v1.1 J9RDO that I looked at have play in them despite proper torque. Other threads on this board address a similar issue, including perhaps on the R9RDO. A RWC needle bearing kit plus shims are forthcoming to seat everything down.

    I'm wondering now if these cracks surrounding the lower shock bolt and loose hardware are related?

    The fact that Niner is willing to take responsibility and provide replacement frames makes me very happy.

    I wasn't so lucky with my road bike recently. After 5 months or so of riding I noticed a little crack on the seat tube. The manufacturer didn't want anything to do with it and the dealer wasn't of much help either. I ended up getting a replacement frame (at a discount at least) and am now waiting for the bike to get built. All in all it's been over 4 months now.

    I think you might be on to something. When installing my RWC needle bearing kit on the upper shock bushing I noticed the lower felt a little sloppy. I made a concious effort to NOT overtighten that shock bolt which could crack the CF due to tiny space . So far, my Vanna White Version 1.1 hasn't cracked in this spot. Keeping my fingers crossed.

    I still wonder out loud if carbon is a good frame material for trail riding. It is a great race bike material. It just cracks.

    I would not worry about this at all. If it cracks, get a replacement from niner, but you should be able to keep riding worry free in the meantime. It may be a real flaw in the layup, but looks very cosmetic.

    Just what I was thinking as I read this thread. I have a carbon road bike and have owned a couple of carbon mtb's, but right now my mtb's are steel or aluminium framed.

    For us weekend warriors who will never worry a podium I am questioning the value of paying extra for a carbon mtb frame. Its not the weight of my bike that is slowing me down I can assure you.

    I think what this thread has confirmed for me though is if I ever buy a Niner carbon frame I will make sure it is from a dealer and with warranty. Note, my Jet 9 was bought second hand with no warranty but my other Niner frames have all been bought new and warranted, never had a claim on any of them luckily.

    Glad Niner is taking care of it. Although I can't buy the "less than 1%" proclaim. Unless the original poster and the other guy on his 3rd frame are VERY VERY VERY unlucky individuals. What are the chances of receiving a <1% defective frame more than once?

    More than once is 1 in a 100, given that the first one cracked.

    More likely however is its batch specific, but they can't identify the batch. Option 2 is that lots of owners haven't noticed within that batch, eg licorice frames might be very hard to see, the vans more easily. Also a number of people might assume its a scratch, not a crack ( mine sure looks like only a scratch, it's just that I saw it early and know there has been no incident that could have scratched it).

    ^I also installed the RWC needle bearings both top and bottom this morning. To get the lower to seat properly with no side to side play, I had to use one very thin shim washer (also available from RWC or Niner) between the bearing cap and frame mount. A second shim was just too tight a fit to force it.

    All now quiet and like butta.

    Good Day MTBR Community.
    I am new to this forum but would like to take the opportunity to comment that my frame has also suffered similiar circumstances.
    I purchased the new frame early 2013. First ride at local park was on April 11th see photo.

    Bike was ridden close to 100 miles before cracking above the bottom bracket area started developing. With every ride the cracks get worse....

    I contacted the dealer who sold the frame to me and they requested I send them photos so they could in turn send to Niner.
    This was about two weeks ago. I just contacted the dealer to see if there has been any response and they told me that Niner has not commented so far.

    Here are some photos of my bike before and after...

    I dont know you.... but I can tell this pic was taken at Amelia right? Anyway, I know another rider that rides Amelia very often, and coincidentialy, he showed me this past Saturday, that his had cracked right were yours did. He had however already gotten in touch with his dealer and was arranging the last little details for the frame swap. He wasnt very happy that he was going to have to pay again for getting the bike build though.
    Since this thread popped up, and then saw his bike, I have been ultra inspecting my frame after every ride. Mine is black so it would be a little harder to detect. Thankfully it looks like mine is OK though. Im glad that Niner detected the problem and is addressing it how they should. Maybe you should try contacting Niner directly. Good Luck

    dang.... although these cracks appear to be different than the original poster's photo, I'm beginning to think this may be a bigger problem than just the 1%er......

    MR Danvar
    Yes you have a keen eye.
    This picture was most definitly taken at Amelia.
    I rode the Niner there for several days before taking her on what we call tour d parks. In one day we rode Markham / Oleta /Va Key and Amelia. It was only at the bike wash @ Amelia that I noticed the first crack appearing. With every subsequent ride they have been getting larger and now the frame creaks with every crank and it gets annoying. Suprisingly the frame hasnt failed completely but then again Amelia is not known to be rough on bikes. I typically put in about 80 miles per week at Amelia

    I have a close friend who had last years model (Black and White) and he has had the frame replaced once also in the early stages of owning the bike. His dealer got the frame warranteed but also had to pay for the tear down and assembly. Eventually I too will have to face that situation but for now I just want an answer.

    At least in Miami within the four parks in this area you will find a balance of Niner Jet 9 RDO owners that have had their frames crack. The more people I speak to the more the problem is evident.

    As for your frame.... I believe you are safe. This is something that is either going to happen right away or not at all.

    I will be contacting Niner directly and ask why they havent responded to the dealer and hopefully I too wont get pushed to the side.

    I ride Amelia often so if you see me out there feel free to say hello.
    I just got some flourescent yellow Sidi shoes so I am not hard to miss.
    I also ride a Cannondale Ultimate Flash (Black and White)

    Jet 9 RDO Frame Crack

    I'm a S.FL guy too. I've ridden mine (black&white) only 55ish miles since last week and I have been keeping an eye on it and haven't noticed anything. I do notice it starts to creak after a few miles, but I'm not sure if its dirt/dust getting somewhere or what. I've been mostly riding Quiet Waters, but I did ride Markham too. I'm a heavy guy at the moment, 245lbs.

    I do want to say that even if a handful of people on MTBR are seeing it, it's still anecdotal. There's hundreds if not hopefully thousands of these things out there.

    Just wanted to give you all an update. Shortly after posting on MTBR and contacting Niner directly I received a very supportive and thorough explanation to my personal delay in receiving information. As of yesterday I have a warranty specialist from Niner working on my case and I am next in line to receive a new frame when the next batch of Large Greens comes in June. Unfortunatly there are no large in stock from Niner.

    So are you getting a V1 or V2 with the carbon rocker and 142 rear through axle?
