WC Helium Friends w/ Extendable Slings and Thumb Loop?
|
I was climbing today at a local crag in BCC, I look over and see this climber with a set of Helium Cams that had extendable slings on a thumb loop. Probably in town for the OR Show. He told me they will be producing them in October sometime. |

Im just repeating what the guy told me. He told me that there was spectra cord (like an actual piece of cordage) inside the sling. |

since when do dragons have thumb loops? |

Those could be the old prototype dragons |

Increase the diameter of the stem wire. BD is stuck with the non-extendible sling because the thumb loop is a relatively small diameter wire with both ends terminated in the head (which means there's no swage at the thumb loop, and reduced weight). Downside to this is the smaller wire will cut an extendable loop at loads lower than they'd like to rate the gear, hence no extendable loops on C4's. Simple answer is increasing the diameter of the stem wire, but that means more weight on an already heavy design, so it's not going to happen. |
