colnagos have more "front" due to slacker ht angle. i'm curious to know how different they handle to other italian bikes with steeper ht's and tighter front and there's nothing around to test. btw, i ride 53/54 c-c.
My '98 Colnago Crystal vs. my old 80's CinelliDale Brigham

Both bikes have same frame size (58 ctc, or 59 ctt) and top tube length (57 ctc). I have same stem length (12 cm, quill) on both; and saddle height and overall reach are close to the same. Both frames are Columbus steel with steel forks. The Cinelli has the "traditional" steeper head tube angle; the Colnago has the slacker head tube angle you note above. I'd guess this is close enough for your comparison.

In short, I like the way the Colnago rides a bit better than the Cinelli. It seems to me to have better stability (best no-hands bike I own), but is plenty able to turn quickly. (Of course, I have never ridden a bike that wouldn't turn as fast as I wanted.) I think the Colnago feels a little more stable when climbing out of the saddle. These, of course, are very subjective opinions, and I have no data to back up any of this. Also, I value stability and straight-line tracking over "quickness" in bikes. You might not.

Both bikes work just fine (it's the rider that causes all the problems). I'm no bike geometry expert, and I've never measured the front center on the bikes to see if there is a notable difference. If you are worried that Colnagos handle weirdly or are in some way deviant from other bikes, I can assure you that that's not been my experience.

I've lusted after the more simply painted Colnagos over the years and ridden a few hoping to love the fit and ride. The top tubes are a short for my long arms so I've never bought one, but not because there was anything wrong with the handling. They feel different than the long, low bikes I ride, but perfectly competant and after a few minutes quite natural.
Colnago geometery has changedNessism

Old classic Colnagos, that used curved steel forks, had different geometery than what the new framesets use. These older chrome forks typically used 50 mm of rake unlike the current Colnago standard of 43 mm. I'm not sure but I don't think the steering head angle has changed much during this same period. One thing I do know, current Colnagos have a lot more trail than just about any other frameset being sold today. Good or bad? Not sure.

In my opinion, the one size fits all fork strategy is not ideal. I think Colnago is going this way for economy - maybe they think most riders don't know the difference.

Good luck.
