Carbon Poles vs. Alum?
If you whack your boots with your poles (whack the sides of the soles)
to knock snow off the bottom of the boot, my experience is that carbon poles will rapidly fail, aluminum won't. Hmmmmmmm....... that sounds pretty unreliable. Was this a while ago (maybe material improvements have been made)? I was using the NNN BC step-in bindings, raising each boot enough so that when I whacked the boot to knock snow out of the toe pin area before stepping into the binding, the basket would pass under the sole and the pole itself would hit the side of the sole at a point an inch or so above the basket. The fiber poles didn't get "cut" -- they just gradually (but fairly rapidly) disintegrated into a lot of parallel fibers, with no remaining function as a tubular pole, for the first three or four inches above the basket. The local ski shop just advised me, "Yup ... don't do that". |

The local ski shop just advised me, "Yup ... don't do that". Related - my kid destroyed fiber poles in the same manner (except up near the grip) hitting slalom gates with the poles. For backcountry use I'd think the possibility of field repair of aluminum poles using a whittled wood dowel insert and duct tape would be a consideration. There's also the interesting matter of the "better" aluminum alloys breaking rather than bending, where the dirt cheap alloys bend substantially and can be bent back. |

Is carbon too fragile for backcountry skiing (ie; they break instead of bend like aluminum) Aluminum crimps. I'd think good carbon/boron/etc composite poles would be MUCH better - any accident that would break them would also break aluminum, and not necessarily vice versa. Dan |

[ gr ] Is carbon too fragile for backcountry skiing (ie; they break instead of bend like aluminum) I've broken aluminium poles (in two places at the same time, even -- I hit a tree). I've now had Black Diamond's Pure Carbon poles for a couple seasons, they're still fine, but I haven't really had any accidents where they could have broken. Carbon XC ski poles do break, you see pieces along the ski tracks sometimes, but I suspect aluminium also would have broken in those instances, or at least bent to unusability. Martin I still use bamboo (and have broken them, too). Dan |
