Snapped Wire Toe Bail
|
Had an interesting experience over the weekend... Wire toe bail on the lynx snapped mid-lead on a section of moderate ice. Appears to have broken right on the bend. Kicked, didn't get a good stick, looked down and watched the bail bounce down to the ground below, crampon dangling from the strap. Replacement in the mail... Never seen or heard of anything like this. Have you? |

How old are they, how much do you use them? |

Hard to say without a macro photo, but there seems to be a an older crack in the rupture zone.Second season, they've got less than 75 days. Hardly "old" by gear standards. Replacement on the way. Macro photos incoming... |

I'm no metal expert but that doesn't look right.... eh? |

Pretty common, especially with Petzl. Looks like metal fatigue to me. BD bails are much beefier if it still fits your boot. |

You weren't the dude next to me on Positive Reinforcement that broke his crampon this weekend were you? |

If you have narrower scarpa boots their small bails fits the best out of any brand by far. They do sell bails individually on their site also. |

Petzl bails (older than 2014ish?) explode. I put 40 days on them, then change them out. Change as often as your comfort level requires. Apparently have been redesigned lately for newer models and won't explode anymore, according to the local rep. |

I broke a bail several years ago. There was a sharp crease in the inside of the spot where it broke. The bails that I have had since then are all very smoothly radiused inside the bends, so no stress risers. |

Such a simple thing.They've actually had them hidden away on the site for years, not in with climbing but just misc parts (tent flys, C4 triggers, etc). I ordered some to convert my petzl vasaks to full auto last year. I managed to order the ONE remaining small toe bail they had in stock last month (not doing me much good without a second). It is a slightly different profile than the older small stinger bail. Smoother radius that hits more of the boot instead of sharp angles. |
