    Scary reminder to check chainring bolts!

    Midway through a 47-48 mile ride yesterday I started hearing a regular chain noise and thought I might have suddenly developed a stiff link. This didn't seem logical in the middle of a ride especially since it recurred at the same spot in the crank rotation rather than in time with the chain. Loose chainring bolt did cross my mind, but I didn't see how they couldn't have come loose so I kind of dismissed the idea. After quite a few miles I decided I really needed to figure this out so I looked down at my crank and, sure enough, at least one of the bolts seemed to stick out farther than the others. I pulled over to check and THREE of the bolts were so loose they might have fallen completely out in a few more miles. Another was somewhat loose, and one was still tight. Yikes! I tightened them all up and continued home. It was a little scary to see just how loose those bolts had gotten without my having realized it. So check those fasteners often just like all the books say!
    If it ain't broke, mess with it anyway!

    When I first bought my new bike the first thing I did was to tear the whole bike apart and grease/oil/adjust everything. One thing I did was to put some lock-tite on the chain-ring bolts. I figured that this is one item that I don't regularly take off so I used the "red" lock-tite. No problems yet. Glad you caught it before the bolts fell off.

    Even more embarrassing is having a crank bolt come lose during a ride ...

    LOL, I remember the same thing happening to me, about 1/3 of the way from Spokane to Pullman. ALL the bolts were loose

    Another bad one: having a derailleur-pulley bolt fall out and spill your pulley parts all over the road. Been there, done that

    Word! That bites in a big way.

    Once it happened to me as I was starting a trail. It just went POP!! Took me friggin 30 minutes just to find all the pieces and get the thing back together. Then I had to hammer like crazy to catch my brothers who had started a good 10 minutes ahead of me(They have a knack for loading their bikes such that they can get theirs off first, and then leave me to locking up the car and stuff like that). There's no way I could let them finish the trail before me, no way. I caught them on the last climb.
    Booyah!!

    Rainman,

    I've noticed that chainring bolts are even more prone to loosening if not well tightened on a fixie. I'm since become very particular about chainring bolts on my road fix.

    Bikes are either fixed or broken

    Dave,
    I had intended to ask if this was more of a problem on a fixed gear. Thanks for answering the unasked question!
    Regards,
    Raymond
