if I remember correctly, in the mid-late 80s Merckx introduced his frames with "century geometry" which had more relaxed STAs, slightly longer c-stays and a lower bb, and for a few years he was offering this model alongside his more traditional and vaguely Italian style road frame with steeper STAs and shorter c-stays. Now he only offers the "century geometry." I wouldn't consider Colnago or Ciocc to be "century geometry."

Clearly previous poster has never ridden an Italian frame in comparison to twitchy, steep head-tubed US bikes. Most Italian frames have a slacker head angle which makes their steering more docile, as well as a more stable and certainly highly recommended for centuries far more than any Cannondale, Trek or suchlike.

huh? I've only owned a few (Guerciotti, Bianchi, Faggin) and ridden quite a few more (the Colnago and Ciocc that I mentioned, amoung others). And where did I mention HTA? I was referring to STA, bb height and c-stay length, and I was mostly talking about what Merckx calls "century geometry"--not whether or not you could comfortably ride a century on one. It's all generalizing anyway...(like those "twitchy" US bikes--???) The Merckx Century is in fact pretty quick handling with a steep HTA and not a whole lot of trail (own one--even ridden it a few times, too).

(knew I'd get in trouble for responding to the original question, but Colker is my buddy and no one else was responding, so...)

In my experience it's hard to find a lot a similarities among the various Italian frames on the market. For the most part though they do seem more geared to long rides vs. the crit geometery that is so common here in the states. A couple of things I have noticed about Italian frames is the shorter top tubes and lower bottom brackets. Also, many of the older ones tended to use slack head angles and forks with a lot of rake - 5 cm was not uncommon. Not sure about anything else.

If I recall, the old "classic italian' geometry was a relaxed ST angle and a long TT. They followed the anatomies of european road racers who had long legs and long arms. I owned a Gueciotti SLX and the TT was way too long for me to be comfortable with. Cinelli is another one. Things changed when they started manufacturing frames out of different materials. I think Merckx came up with the term, as that's the way he like his frames made, hence "Merckx Century Geometry".
