    Air9 RDO flexing

    I recently noticed what I thought was a little bit more flexing than normal in the bottom bracket area of my bike. Also, the drivetrain started to sound a bit loud under load, similarly to cross chaining, and some creaking when putting down power in the flats. My cassette is in great condition and my chain relatively new (80 miles) and I keep a clean drivetrain.

    I took a look at things and did notice what appears to be some stress cracks around my BB area. There are now some stress cracks developing on the non drive side as well.

    Do you think it's okay to keep on riding? I have a couple of rides planned coming up over the next couple of weeks that I don't want to miss, but I don't want to have an issue on some roller coaster/G-Out section of trail.

    Niner will likely replace it. I submitted a claim on a monday, a new bike was in the mail the same day, and I had the replacement by friday.

    I kind of figured they would more than likely replace it, since it's less than a year old. That is something I am going to get the ball rolling with my "LBS", but I am just wondering if it's completely safe to ride for a few more weeks without risk of catastrophic failure?

    It probably won't fail catastrophically, but if it does, you're going to castrate yourself on the top tube.
    Hope this helps.
