We have a few bikes for show, this is a columbus SL with full shimano AX600 aero group. It’s absolutely perfect and the tyres are new, so it just needs some air and someone to ride her.
It’s for sale, I’m asking 950euros.

We are all part of a tradition, sometimes we accept it, sometimes we try to break away.
Both reactions are necessary, tradition is a way of doing things that was so good it was a good idea to pass the knowledge on.
But, breaking from tradition is part of tradition, situations change, and new solutions to different problems must be found.
Understanding why things were done in a certain way gives you a key to solving new problems building on the solutions of those that came before us.
This is the first bicycle this factory ever built, they used hearth brazing back then, fit was very different as well, the founder, Renato (passed away in 2006) was around 176cm tall, yet rode a 62cm frame.
He grew up in France as his family emigrated from Italy due to political reasons. There he became an avid cyclist, and when he came back to Italy he set up a small factory after apprenticing to a framebuilder. He had also Worked at an arms factory in Florence, and used to talk about having to file blocks of steel perfectly flat with just a file.
Back to his bike, it’s got some lovely touches, the brake bridge for example is very elegant, as is the fork crown, some I’ve seen in mtbikes, like my Evil Sovereign: the plate for both chainring and tyre clearance on the drive side chainstay.
Some things would later change, like drilling a hole at the end of the seattube slot.
The Simplex derailleur mount would become the horizontal one we all know, then that would be abandoned in favour of a hybrid:vertical but with the rear deraileur attached in the newer position.
I haven’t tried a modern Rd on this, I’m guessing changes would be slower, but it should work.
It’s branded NILOR, as being a contract builder they didn’t have any badges made, and the though of a bike without a headbadge was just wrong, the paint is not original, he rode his bike until he stopped riding in the mid 90s.
It’s been painted about six times at least, in those forty years of service.
Steel, it really is real.
Mudguards can be fitted too, as well as big tyres.
So basically what’s new is old, and what’s old is new.
Tradition, it’s everywhere.

Temperature can be measured in many ways.
Spitting on an iron was a quick way to see if it was hot enough.
Colour is a very precise, repeatable way of measuring temperature.
The only problem is that until you know what colour corresponds to what temperature it’s a very empirical system- ie, the brass starts flowing at a certain colour (cherry red), spits because it’s too hot at another (straw yellow).
I know the temperatures from the charts published by the companies that sell me the brazing material.
But I wanted to be more precise,as well as get a better feel for the colour temperature, as the charts published all differ slightly.
So I got some zip ties…
