Columbus EL tubing or EL-OS

jordic1968 · Nov 7, 2018

I've seen a bike with a columbus EL sticker, but also saying "reinforzati". Is this the EL-OS ??

Because I've never seen an EL-OS sticker , and I believe the one just saying Extra Leggere is the plain EL while the one saying reinforzati should mean the oversized version. (I'm far away so I can not measure the diameter of the tubes that I believe should be the right way to conclude if OS or not OS

Thanks!

'Rinforzati' is for butted tubing

ok, got it. So reinforzati is not oversize, but double butted as EL is. Thanks for the quick reply!!!!

Re:

EL-OS stickers had the words OVER SIZE in red either side of the dove, If you see what I mean.

Mark.

The (oversized) tubing diameter dictates whether or not it's EL or EL-OS

EL: TT 25.4, ST 28.6, DT 28.6
EL-OS: TT 28.6, ST 28.6, DT 31.8

All the best,

Columbus EL tubing or EL-OS
