    Vivalo Fork Failures

    Just a quick public service announcement. It seems there was quite some discussion about Vivalo losing their NJS certification due to an issue with forks (or A fork) failing. Wish I had seen this before I bought my frame! The headset always felt a bit wonky and at one stage I even took it in to get looked at and the mechanic changed the headset which worked for a while.

    Then about a month ago, I was riding to the station and it felt really loose. But it was only a short trip and I was late. On the way home, at very low speed thankfully, the fork separated from the tube and I fell over forwards. Luckily the wheel was standing upright and I bashed my face on the wheel rather than the pavement. Anyway, fork is cashed. My face escaped with only 3 stitches and a few hours in the ER. Here's the evidence:

    I'm sure most people riding Vivalo's are safe, but if you think your frame might be from the batch where the defects were found, then can't hurt to check!

    How in the hell did the mechanic not notice a cracked fork crown when swapping crown races for the new headset?! Good to see you didn't get too injured.

    Would it be possible to get a close up of the steer tube and crown?

    Those Vivalos didn't have cracked fork crowns. The steerer tubes simply separated from the fork crowns due to improper brazing.

    I can't seem to make them appear larger, however, if you click on each image you get a better view.

    Looks like there was nothing but "good karma" holding the steer tube in place all along! Glad you weren't injured more seriously...
