does anybody know about the stiffness of this frame or other similar older carbon frames?
Is it's stiffness comparable with steel frames made of standard round tubes or is it much lower.

I used to have one. It was an excellent frame. The frame felt stiff and the carbon fiber tubes really absorbed road shock well. I went to a Klein after the Allez and the Klein I couldn't ride more than 50 to 60 miles without feeling really trashed. I would actually go home and take a nap after riding the Klein. The Allez I could ride 80 to 100 miles on it and feel great after I was done. I also had used it to compete in many duathlons, it was an exellent time trial bike. I just saw one on Ebay and I was very tempted to bid on it although the S.O. wouldn't be happy me adding another bike to the stable.

I still have a '92 Specialized Epic Comp. Same/similar carbon frame, it was re-named at some point. Still in good shape(in fact my bro' in Seattle still rides his Allez). I'd compare the ride to a steel frame of the same era.

Beware of the durability. One of the aluminum lugs broke on mine. From what I've heard, this is somewhat common.

As far as how stiff the frame is, I'm not so sure. As I recall it was comfortable to ride. I know one time I had to do an "emergency stop" at about 35 or 40mph and I thought the frame was going to snap. It was bucking and oscillating from side to side. I didn't know a frame had that much range of motion. Amazing that I stayed upright. Not sure if this tells you much about the stiffnes, but thought it might help.

bought it used after checking up on their history of coming apart at the glued joints and making sure I got a good deal so that I could recover most of the money by selling parts if it came apart on me. 6 weeks and 600 miles later as a bad weather/commuter bike and no problems.

Mine is a 92-93 model year and looks almost identical to yours but is purple and gold. My LBS says these type of Trek & Specialized frames had a history of coming apart early on, before they figured out the gluing process. Says my frame is on the late end of this phase and I will probably be fine if I give it a quick rinse on a hot sweaty day since it looks like it has hardly been ridden and the roads aren't salted around here. And, as I already pointed out, it wouldn't be a big financial loss for me if it came apart tomorrow.

That said, I like the bike and don't let the skinny looking tubes fool you since it is surprisingly stiff. It's not like the main bike I'm used to and comparing it with (99 Klein quantum with Chorus parts and Kestrel bars) is a noodle. I'm no giant, but am a fit 175 lbs and capable of bringing out most differences. The Klein is in a different league as far as stiffness and weight goes, but the Specialized is certainly stiffer and lighter than the steel as well as many aluminum frames of it's day. I haven't ridden modern steel, except a Lemond briefly, so can't compare.

It is also significantly stiffer than the 95 Trek 2100 I had for almost five years, particularly in the bottom bracket. Both have aluminum forks and the Trek fork felt like a pogo stick when turning or braking hard. The specialized fork is much stiffer and also not as smooth. Neither is as smooth or stiff as a decent carbon fork.

Between the 2, the Specialized is a better racing or weekend warrior bike than the Trek. It has carbon seatstays and chainstays whereas the trek uses aluminum. The frame is also a bit heavier which might contribute to the stiffness. It has slightly tighter geometry, although both bikes are decent. The specialized is neutral when upright yet still turns quickly in a turn due to the tight wheel-base. It feels more stable than my Klein yet capable of turning almost as quickly. The trek is slower to respond than the other two, although still respectable and not a limiting factor in beginning to intermediate level races.

The specialized ride is kind of strange, I think, and seems to be more affected by tire pressure than either my Klein or old Trek. Generally, it transmits slightly less buzz than the Klein but is actually more jarring over cracked pavement and expansion joints. Although I haven't had it for a couple years, I think the Trek was by far the nicest riding of the three. It was lively with a good feel for what the road was like, yet still very smooth, much like a steel frame. My guess would be that a steel specialized would be a good compromise between these two bikes if you aren't concerned about weight. Hope this helps.
I have one too...satanas

...it's probably a 1990 frame (bought in 1991). It's been ridden tens of thousands of kilometres and is still going strong. Stiffness is about the same as SLX, with good vibration damping on coarse aggregate, but fairly stiff over bigger bumps. Original alu fork is *very* stiff/harsh, but handles very well - I'm using a Look fork which is comfier but not as precise.

You will hear some people say that these frames are too soft, blah, blah, blah, but that's what welded oversize alu is for. As for durability, mine has been used for loaded touring in the Alps (light front and rear panniers) without problems. I think that the Allez Epic is a good frame; pity the seat angle is so steep... :-(

If I ever had enough money to order a Seven, I'd get them to make it as laterally as the Allez, but with a softer ride and a 71/72 degree seat angle - not 74!
