Weaknesses: none considering it is aluminum
original wheelset (see summary)
Have owned this bike since new in 2004. Was originally reserved for racing (it was our team bike)but eventually replaced by Xenith Team and has been relegated as a training bike ever since. I now have an S Works Venge so am in the process of selling the Bianchi. That being said, it has been an excellent ride, very compliant, not buzzy, quite snappy, lightweight (but obviously not as light as the other 2 bikes). It still would be the preferred bike for a reasonably flat century ride since it is the easiest to ride of the three. It climbs and accelerates well but not in the same league as the Jamis and S Works. The only negative comment would be the Shimano wheels that it comes with are mediocre and I replaced them with Ksyriums right away.
I bought this San Lorenzo frameset used through Craigslist. Since then, I've built it up with Campagnolo Veloce components and more recently Shimano Ultegra.
The frameset is astonishingly light - it's one of the lightest aluminum frames on the market, and weighs less than many carbon frames. At 1045 g for my 53 cm, the San Lorenzo is an great way to get a light machine.
The geometry is very race-like, with a horizontal top tube. Tracking is precise, but because of the responsiveness can feel 'twitchy', especially when out of the saddle. Acceleration is noticeably very quick. Climbing is a blast.
I have one or two complaints: the shift cable stops are placed a little too forward on the downtube for my liking, and the housing has no choice but to rub heavily on the head tube. Also, the variable-diameter tubing causes a LOT of annoying cable chatter if you forget to install those little rubber cable silencer 'donuts'.
Overall, though, the San Lorenzo is a very capable frame ready for racing. You can easily build it up to 15 lbs or less with the right mix of components.
Strengths: Lightweight, price, fairly stiff, and compliant for aluminum.
Weaknesses: fragile paint, flimsy fork
I purchased the bike as a frameset on Ebay; thus, none of the components are the same. Overall, the frame is terrific. As previous reviewers have pointed out it is incredibly light. It has a reasonably stiff ride, but isn't terribly harsh. The paint looks good, but does not have a clear coat, looks bad when dirty, and scratches easily. The stock fork is garbage. It is also extremely light, but extremely flimsy. The star nut in the steerer tube also comes loose. I have a friend who rode the same bike and had the same fork problems, which suggests to me this is not an atypical problem.
Strengths: ultra light weight, reasonably comfortable for long rides, especially with carbon seatpost. Classic celeste/silver/black color scheme.
Weaknesses: -rear brake cable makes noise and scratches toptube (put the cable in a length of rubber tubing to fix that problem)
-doesn't have structural foam injected seat tube, so water could get into the BB area
-straight rear stays can transfer vibration to the rider
-grease and road grime show up easily on the celeste paint
-no aerodynamic features (like the Soloist or Look 485)
This is one of the greatest bikes available for a resonable price. The frame is well within the range of ultralight bikes (1000g for 49cm), without spending a fortune. The ride quality is good, although not as compliant as steel, but feels good. The San Lorenzo flies up hills, and doesn't flex at all when I'm out of the saddle hammering. The celeste paint must be kept clean to look good, but when the sun glints off it, there's nothing like it.
Looking for a road bike and trying to decide between these two.
Both are 2004 with full Dura Ace. They are close to being in the same condition as well. And price would be the same.

I just bought a 2005 Bianchi San Lorenzo(Scandium) with Duraace 10 speed and Ksyrium SSC's - Can't wait to get it, it's in excellent shape. Does anyone have any feedback on this bike? Thanks Appreciate in advance.Read More »
Hello fellow riders, does anyone how the San Lorenzo rides?(acceleration, cornering climbing-I know it's a race bike, but just hoping to hear from people who have raced on this bike.)
And what the estimated weight is? Lastly, how strong is this frame?
ThanksRead More »
I just built my first bike from the frame up.I am pretty excited about how it turned out, so I figured I would share.
The frame is a brand new 2004 San Lorenzo.I got a good deal on it from my LBS.The complete drivetrain and brakes are Ultegra 10 speed.I went with the Ritchey WCS OS bar and stem.T ... Read More »
