Word to DaveLeeNC and anyone else who might care to listen...................

Dave, do not EVER concern yourself with weight, it's a loser's game increasingly and tragically played out well into the past decade plus, plus with sickening results by far too many who are either too dumb by choice or chance to see the pernicious folly. If, as the label indicates the tubing is EL (Columbus) on that modified - obviously greater set back seat tube, that tubing is/was essentially (one of) their lightest offerings ever, especially in the standard diameter not oversize offering which was also manufactured. Few tube sets if any to this day still are as light regardless of mfgr. Hopefully your physical weight is in proportion to your height as EL was not intended for heavier weight riders for starters...............

Concern yourself with any bike as per same being a solid, sturdy, reliable foundation (as all bike frames potentially are - should be but not always are) for what should be clearly solid, reliable componentry (in your case Campy - be thankful more than you know for that!) and above all solid wheels.........., the single most important component on any bike, period. Never cut corners on wheels. Never, ever.

You've cleaned the bike completely - hit it with a decent car wax or sealant, checked everything and spec'd fully as if building from scratch/brand new............, beginning with all bearing units (headset, hubs, BB, cassette), cleaning, re-lubing and calibrated to perfection, made certain the chain is right and well lubed always, right? Of course you have. Take it from there.................
