I have just ordered a Calfee Dragonfly Frame. Weight of the frame is 875g and the fork is supposed to be less than 300g. It is a carbon frame and will have a nude finish. It will not be ready until mid January so i am in the planing stages. Looking to build this thing ultralight so any info or suggestions will be great. Here is some of my ideas so far.

What about the air in the tires?

Don't forget to add the plane ticket and other travel costs to go to Europe to pick up the AX Lightness seat. They are unavailable in the U.S. I've had many a conversation with Axel himself. He does not and will not sell to the U.S., there is no distribution in the U.S. As a matter of fact he cannot even supply the demand for his saddles in his own home country of Germany.

The only way to get one is to go to Germany yourself hoping that he'll have one lying around the day you're there. This is highly unlikely. Otherwise, you'll need a friend over there to get you one.

I can't remember the name of the pro who used to ride without bar tape, but he won some key Tour climbing stages (Pla d'Adet, and maybe L'Alpe d'Huez).

Don't forget to replace get titanium replacements for all the derailleur hardware.

Do you really want this light of a bike? What do you weigh?

Sounds like a very expensive and fragile ride.... perhaps even dangerous (depending on your weight) under the wrong conditions.

Be careful on that rig and don't be too upset when some guy with cutoff jeans and sneakers kicks your ass with a 21# "10 speed". It's a cruel world out there... and money don't buy speed.

Sounds like a fun project but I hope your physique doesn't match your handle or there's going to be a big snapping sound. How much do you expect to spend on your project bike?

....or just bragging? I fail to see a question in your post. How much is that frame? $3000?

You forgot to add the weight of your speedplay cleats (they are heavier than most cleats). I can't imagine having a use for the bike, unless I won the lottery. It is too expensive to race (I at least expect to crash) and too light for distance riding (I doubt it is comfortable)... and for training there is something to be said for a heavier bike (generally more reliable and the added weight provides a better workout). I'm not trying to pee on your parade, but it seems the primary point is for bragging rights- a sub-13 lb bike! I'm guessing actual weight would be considerably higher- since they don't actually sell the parts "by weight" I don't think they are obligated to meet advertised weights- and I'd add at least 10% for error- they probably sorted through 1000 stems to find one that weighed 110g, etc....

Take a big dump and relieve "Little Chubby" (ask Jocelyn Elders for more info) before you ride.

I can just imagine you riding this thing with two jumbo water bottles full of Coke, and Nashbar saddle pack, and a Zephal frame-mounted pump.

I weigh 150 lbs and have been into building light bikes for a while. Both Mountain and Road. I have a Santa Cruz Superlight that weighs 18.8 lbs and a Trek 5500 that is 13.9 lbs. A light bike built with the right parts spec is not fragile at all, to the contrary they are very reliable. I also ride 5 times a week and can hold my own for a 40 year old. Im not into braging rights its just a hobby i really enjoy and thought i could get some ideas from this Forum.

Thanks to all who are serious in their recomendations

If you want light...few

A campy 10 spd drivetrain would be lighter. that way you could also use the sweet carbon crank.

you might do better with tune hubs, and consider sapim xray spokes.

A company called Stella Azzurra makes a reported 100g mag stem
