It's a DBS internazionale With a Columbus double butted steel frame, the bike is from around 1995.

Would it be sensible to Upgrade this bike to a modern style groupset, or even possible ? The current setup is a 42x54 up front, and seven gears at the rear, low end Shimano system With shifters on the brake handles.
The brakes are quite poor, and the gearsystem needs some tuning to work properly. Its very hilly were I live, but of course I'd still get up 99% of the hills even With the 42 small chainring.. But for a bike that should be set up for long slower rides, lower gearing would be better...
The tires are super skinny at 20', but upgrading to 23 or 25 will change the great look that they give. Bad asphalt and bumps are standard, I'm afraid keeping the skinny tires are a bad idea even though they are stylish..

Of course another option instead of upgrading is to ride it like it is to remind myself how hard the riders were in the 90s :-)

Not sure it has enough quality to justify spending a bunch of money. Still could be a fun bike for casual riding. It looks to be in good condition.

You are probably right, I just loved the look of the frame though. A Complete tiagra 10 speed Group is about 300 usd, or 2600 NOK, which is a bit of Money of course, still half of an entry Level bike in the shop though, so as a backup training bike it is not too much Money. The problem is if even half of it would be possible to install on this kind of bike...
Probably best to just add some wider tires, and use it for rides into the city or to the shop :-)...

If everything 'works', then I'd ride it as-is, but with new tyres (e.g. 23mm).
And do a complete clean & grease of hubs, headset, BB, pedals. Brush & oil the chain, deraileurs, and freewheel.
Dribble a little oil in the ends of the cable housings.

The bike looks good enough to set up as you like but probably not too much money. I like the chrome look on steel frames so no black components for that bike. I would replace the rings to a 53/ 38 0r 39 and look for a set of 10 speed shifters, rear Der and wide range road cassette. 25 tires new tape, cables, and probably a different saddle. Cuisse SS cages with the buttons.

One of the issues with a bike of this vintage with a 7 spd rear is the hub will have to be modified to take a later groupset. Not sure if my memory is correct but the move to 9 speed required a wider rear hub spacing (or was it 8 speed). So a longer axle, potentially a new cassette body and the dropouts will have to be spaced to adapt to newer 9 speed or more groupset.

Personally I would clean it all up, give a good service and ride it as is. I would not try and set it up for a long distance bike although it could be done. Being a steel, make sure you have a good look at the state of the tubing for rust. Old steels often get moisture collect in the BB shell and the BB end of the chain stays which causes rust from the inside. This may not be evident until one day the chain stays snap, I had it happen on a Reynolds 753 frame once and you could not see any sign of occurring from the outside.

Got some help with the gear-system, and everything works very well now. Changed to normal brake-calipers, with better braking-rubber to improve the brakes a little bit.
Also replaced the tyres, put Continental grand prix GT 28mm's on it, for extra comfort. The bike rides very nicely now, with a little extra comfort.

First gear is still quite heavy even if I have 28sprockets at the rear, but not too bad as long as I don't seek out any especially steep gradients, I have a short hill with around 10% on my way home every ride, but that is ok. I'm not going near 20% gradients with it though :-)...

Have you changed the pedals?
If not, then I'd suggest at least toe clip with straps, or whatever matches your cycling shoes for other bikes.

my 1972 Fuji here - http://www.pronetisp.net/~jkosta/Jays_Fuji_Aug26_2014.JPG
6 speed freewheel 28-14, with 42-52 chainrings - original was 47-52 rings that was sweet for shifting on flat but very difficult on hills.

The bike had no pedals, so I put some old pedals on it, Shimano spd kombi https://bikeshop.no/sykkel/komponenter/pedaler/klosser/terreng/shimano/shimano-m324-kombi-pedaler-sølv-spd-kombi-530-gr-per-sett-epdm324-p0000053526

I have some "casual" cycling shoes that clip in on these mtb-pedals, plus i can ride it with normal shoes as well, so that's good.

That looks like a pub bike to me

What is a pub bike then ? It looks like a road bike from the 90s, and many people use old bikes to ride to the pub, that is true. However, the bike is quite good, and there is little difference in speed compared to a modern bike, as long as it is not too steep.

People on carbon-bikes sometimes get funny faces when passed by this "pub-bike"...
