Hello,

I got hold of a Colnago Super (sarroni) of 1982 (Colombus SL tubing). I am thinking of creating a bike with a classic gorgeous frame, with modern equipment(Veloce/Centaur 2009 groupset, carbon wheels,seatpost etc.)

I am doing weekend rides and 200-300 km audaxes. I am not doing menacing breakaways etc.

I was told that the modern equipment maybe too hard as material for the kind of steel 1982 bikes used for frame material and as a result the frame may eventually crack and I should go for vintage series.

Is it true? Is there danger for the frame? Anyone had actually such an experience?

Thank you in advance

The answer is NO. You are about 20 years late. People have been doing that since STI and 8 speeds+ came out.

It was the sweetest NO of my life. A frame builder where I lived told me there would be no issue what so ever but asked at an bike store and they even showed me a no name steel frame cracked from inserting modern groupset and got me scared. Maybe it is the different quality of steel.

^ What he said. This is exactly what I did with my 1987 Columbus SL frame, because I wanted it to be as much fun to ride as possible. A couple of things to take into account; one obvious, one possibly not so...

1. Rear stay spacing - probably 126mm on yours(?) Modern 10 speed will be 130mm spacing, so re-spacing may be advisable.
2. Wheels: a lot of modern skewers are of the "exposed cam" variety as opposed to "enclosed cam", and are not as secure with the old-school horizontal drop-outs. I sourced some Novatec hubs for my new build but was advised to replace the skewers with traditional style Campag ones.

Here's mine.

Old school skewers aren't a bad idea with horizontal drops. Spreading a bike from 126 to 130 is nearly always not a big deal either but you'll want to have someone do it who knows what he or she is doing.

4cm coldest is more like an adjustment, no big deal.

4cm might be an issue; the required 4mm (2mm per side) is not

Check with the frame builder who told you to go with it, and see if they can cold set the frame to 130mm rear spacing for you. This is so little, you can just put the wheel in if you like without cold setting.

That bike store was just trying to sell you a new bike.

Having done a couple dozen frames now I would say no issue. It is a good excuse to get the frame all trued up before you build it up too.
btw most frames get cold set when they are first built anyway

Columbus SL and 10spd ultrashift Campy is a fine combo!

Go for it, ensuring, as others have suggested, that you have knowledgeable help and guidance, if you are not sure how to do it.

I sure like the way my Cyclops turned out. Sadly, I do not know how to properly describe the ride quality, coupled with the New School "user friendly" (my opinion) components...

Not only will you have no issue, but I would say you won't have to cold-set the frame. I now have 4 frames from 83-90 that were originally spaced for 126 and I have had no issues placing a 130 spaced back wheel in them without cold-setting the frame. Good luck and post pics in the classic with STI/Ergo's thread!

make sure you get the correct BB and head set threading, and seatpost size. Maybe what the bike shop was referring to was someone doing something mix matching and goofing things up
