A scary experience
I've had som squeacking noice coming from the front of my bike for quite
some time but have not been able to figure out where it came from or what caused it. Not until yesterday when I suddently discovered that the stem was almost broken. It's got a crack almost around the entire stem along the weld. The stem is a 1" CODA quill stem with an ovalized shape and a matte black finish. Has anybody else experinced anything like this?

Hjalmar No. But, I'm glad that it didn't fail on you while you were riding. Now you get to think about all the "What if" scenarios. Scary indeed. -- Marty |

i had a similar experience...but with a seat post. there was a crack coming
down the post from where the bracket that holds the saddle got inserted into the post. it expanded quite fast too! it was an old seat post but man! it would've sucked to have to ride standing up on the pedals all the way home! i'm glad u found it!

In the case of the bars I heard a creating for a few days and pulled the bars from the stem in order to lug them, and then noticed a crack. In the case of the frame I heard a clunking for several weeks before I found the problem. JT |

AT least with quill stems the expander bolt holds things together (for a while anyway). Moral of the story is that it pays to track down suspicious noises promptly (I didn't notice any noise from mine, BTW). |

Hjalmar I had a Deda quill stem where I apparently over-torqued the bolts on the bar clamp. They decided to stip out ... simultaneously ... just as I was jumping on the pedals to catch a gap between cars crossing a busy highway. I ended up in a ditch on the other side with a set of handlebars in my hands, connected to a bike by cables only. I was lucky not to end up a bloody spot on the pavement. I acknowledge that I over-torqued the bolts, but those Deda stems were made from some awfully soft material. Bob C. |

...Cracks...Not with a stem but with handlebars... I occasionally read the little pieces of paper that come packed with various bike parts. It seems that more than one of the aluminum handlebars I've bought in the last few years has come with a warning that they should be replaced ever 2 years or so. It has to do with fatigue limits, or lack thereof with aluminum. Yeah, like we're really all going to start doing that, right? John -- jmm |

RE/
Moral of the story is that it pays to track down suspicious noises promptly Amen! I rode for about an hour with this funny sound coming from my cranks. Sort of a 'whoosh-whoosh'......thought it was one of my shoes rubbing....stopped a couple times, didn't see anything. Then I stopped at a friends house for some free coffee and BS-ing. As I stood up to stroke out of the driveway, the right crank arm just fell away...broken in half... Subsequent inspection of the break showed corrosion around the edges - so if I'd had my act together I could have spotted it some days before the failure. -- PeteCresswell |

It looks very solid indeed so it was never in my mind that it could break.The crack started at the bottom of the stem right in front of the welding to the bolt and moved up 3/4 of the way to the top before it was discovered.
