That's the only noticeable advantage either material possesses over the cheaper alternatives anyway. Ti has the big advantage of not needing paint and thus looking great. Jasper The other big advantage to Ti over carbon is the metallic 'ping' sound that the cable spacers make when you go over a bump in the road. I love that. Probably just me. |

Ti has nearly the same ductility as steel. Carbon snaps. |

When I was caving in England, using Single Rope Technique, I was warned against using titanium carabines in my equipment. There had actually been accidents because they can suddenly shatter at the low temperatures in caves (about 4 degrees C). We always used aluminium crabs to hang our lives on. |

If titanium cracks at 4 degrees C, why aren't the jet engine fans exploding off of more airplanes? They see air a lot colder than that. |

Different alloys different heat treatments, because of different design criteria. What you say has merit, but mountaineering gear - life and death equipment at that - that gets brittle enough to break in the cold? How likely is that? They must have a very clear warning on them somewhere. Didn't notice any of those the last time I was at MEC. Bernie |
