Thanks for that. The frameset is lighter than my 53cm Merckx Corsa SLX.
It says EL are typically time trialling tubes, quite a bit lighter than SLX, and thinner.
Why use SL or SLX over EL then on race frames, or vice versa ?

I'd posit that the acceleration/deceleration forces on a race frame are greater than on a TT frame, and even if they weren't, TTers are such a bunch of weight weenies that they'd take the risk of a weaker frame for grammes saved.
1.6 -1.7 +/- kg frameset is Columbus EL or equivalent from another tubing supplier
