Columbus EL tubing
I've read recent posts concerning various tubing but saw no mention of Columbus EL (i.e. Extra Leggeri, Extra Light) . I've a frame made of this and indeed it is very light but was wondering if anyone had any information concerning wall thickness, strenght, and composition of the steel.
Thanks in advance! |
There's a better resource I've seen, and there' also some good stuff on the Columbus site as well, but I can't remember the site names right now. Here's what came up fast and was good info, on Google:

I'd be interested to know what that frame weighs. I weighed a 56cm Columbus MAX frame yesterday which was over 2.1kg, so I'm not sure how those weight works -- it could be 'without lugs' |

I brought the whole bike when I noticed the Columbus sticker and fully lugged frame. I had the frame stripped a while ago when I refurbished it with NOS XTR components and a Vicious Cycles rigid fork but never bothered to get a weight. The whole bike is lighter than my road bike, a 1982 Bianchi Superleggera (60 cm) built with SL tubing and campy SR components. I'll see if I can get a weight on the whole bike next time I have a scale handy. |
oh, i see

Sounds about like yours. Cheers. |

hey - fancy seeing YOU here :)

nice chart in the link but aside from weight does anyone know the strength/flex/etc. for el vs. sl vs. slx?
