    uh oh!

    i was riding home from work and got about 50 feet and heard something metal hit the ground and immediately stopped and looked all over the place and i couldn't find anything. i checked my bike and couldn't find any missing crap so i guess i just ran over something and it kicked it up in the air..needless to say that was one sketchy ride home because i was expecting my bike to fall into pieces or something equally stupid. i'm sure everyone has had this kind of thing happen but it freaked me out.

    make sure and check your chainring bolts. i had the same thing happen to me, and thought nothing of it until my chainring folded up like a taco because of a missing bolt.

    haha so i walk out of my room and for some reason look directly at my crank and realize that the dust cover was missing..i'm assuming that's what had fallen off since i heard it from that side of my bike. no biggie because i don't really need those things but i figured since i paid for the campy cranks i would use the freakin dust covers!

    You want to use those. If those threads get damaged, getting your cranks off is a B!tch.
    I'm not one for fawning over bicycles, but I do believe that our bikes communicate with us, and what this bike is saying is, "You're an idiot." BikeSnobNYC

    Same exact thing happened to me (just the first part) while descending a steep hill. Luckily I was headed to the LBS anyway, so they gave me a new bolt.

    Apparantly a common problem. I had to drill a couple out on my current project, and mentioned to my bro that I was thinking of using anti-seize. He told me that most racers use locktite to hold them on, rather than anti-seize to make them easier to remove.

    Same thing happened to me the day i decided to put them in. Except i never heard anything, and assume it was stolen. Then i lost the other one on new years when i was drunk, cause it fell out of my pocket. Lame.

    it is a good idea to check your derailleur hanger bolt as well- mine dropped off and I only noticed it when I was serivicing the drive train and I took the rear wheel off and the derailleur fell off the bike and was dangling by the chain. I loctited the new one on and check it every so often.

    Which is probably less useful since this is the fixed gear/single speed forum. But hey, whatever.

    Actually proper penance would be to spend a weekend knee deep in the Hofbrauhaus. Drink beer and flirt with the lovely german ladies.

    i hate those awful metal sounds. i heard one the other day and jumped straight off my bike. it turned out id run over a coat hanger or something so i calmed down a bit. yesterday though i kept hearing what sounded like something inside my bb was cracked or loose. then last night i had a dream that the whole thing fell apart......weird.

    There are no German ladies it is always full of Japanese or American tourists- mind you last time I went there were some nice looking Japanese women that started doing some sort of oriental dance with silk scarves. It looked quite good but was not quite the Bavarian theme.

    Then some American guy came over and started doing some strange miming toward his beer. It transpired that he thought we were German and wanted us to look after his beer while he went to the WC. "Me go wee-wee" he was saying "you-watchy beer-OK". We let him go on like that for a few minutes while saying nothing then I put him out of his misery and just said "so you want us to look after your beer then mate- ha ha".

    Right ... I asked about this same thing a few weeks ago and was happy to learn that it was not just me who has this problem. I took everyone's advice but the problem persists ... and judging by the responses to this post, other folks are still dealing with it too. So I was wondering if using track/BMX specific cranks makes this less of an issue. The cranks I am using now were made to carry two chain rings so, even though I am using track bolts, I wonder if there is some extra play in my set up that makes these things wiggle loose. So, lets hear from folks with track cranks. Do y'all ever have to tighten up your bolts? My roommate/brother rides a newish Pista and he has never done it to the best of my knowledge.

    On a related note, is it worth spending $250 - $310 on Sugino/Campy track cranks when bulletproofs go for less than $50? Is there a viable middle ground?

    I use road, mountain, and bmx cranks and don't have this problem when they're properly tightened with the proper tools. Without the proper tool, yes, this is a problem no matter what.

    Sometimes I feel like I must be the only person with no locktite involved in the assembly of his bike.

    excuse the newbieish question, but what exactly is the proper tool? is there a specific chainring bolt tool to use?
