I'm in the same boat as a few fellow members, or simmilar atleast in the aspect that i want a damn light track bike. The Cannondale frame is a good start. I'm still waiting around for a gram scale to have a more precise build guide, however I've done a good bit of "homework" to find good buys, because i want light, but money is still an object. The Cannondale frame is a good start in my opinion. Its aluminum, and it's made by the guys who really have some of the nicest alum frame out, in terms of lightweight, ride quality, stiffness, and finish. I opted for the new 07 capo. Why? IT was a lighter frame over the 03 model, for the older one was painted, whereas this one is raw aluminum with some over it. Also, it was cheap, and had crappy parts, so off the bat I was forced to upgrade..., basically everything. While it is not yet finished, my capo plans are already laid out, weather parts are on order/in transit, or actually in my presence. Sure enough, i have changed out everything except the frame. Here is how it went down.
-What everything else revolves around, the frame, Cannondale's capo, should do for now, at a somewhat burly 1400 grams.(500 bucks)
-Steel bottle braze on bolts, now ti, with a cool anodized red look too. weight savings- probably 4 or 5 grams, but keep in mind every gram counts. (18 bucks)
-Seat post collar, another insignificant/ small part most people only replace if stripped, however switching to an m2racer clamp saves 10 grams. (30 bucks)
-Carbon headset, once again no true benefiet sans saving a few grams, and in the case probably just around 10 or so. ($60)
moving on the bigger things...
-Full carbon fork, jeez maybe just shy of a pound alone over a carbon fork with an aluminum steerer. In this case i went from a decent slice ultra fork to Columbus muscle all carbon as mentioned, with ti dropouts too!
roughly 620 to 300grams (free)
seat-post - i went for one of the lightest offerings available without going over $200, and ended up settling on a full carbon use cyclops, at 169 grams, I've save about a 80 grams over the stock carbon wrapped aluminum seat-post Cannondale jammed in the seat-tube. Heck maybe i'll trim it down too, knock it down to maybe 150!

($110)
-Also, cannondales stock saddle is no lightweight by any means, however an slr sure is, but i plan on doing one better by going with the carbon model, saving another 15 grams, and thats in addition to the 150 grams over the canny seat.($140)
cranks, those rpm ain't got nothing over the fsa pro track i have on the way, but they're light, however, i can't say, or guess by how much just yet. (EST $300)
pedals- this bike is going to be raced, so i wanted something secure, yet light, so i chose keo, carbons to be precise. Maybe a pound over some typical platforms with typical clips and straps. (150 bucks)
cog- dura-ace cog, hell anything is lighter that those damn freewheels
maybe 150grams (20 bucks)
-chain- izumi v maybe 500 grams (60 bucks)
For racing the cockpit is deda aluminum track bars and their corresponding aluminum track stem. I'm sure i could have gone lighter but i need stiff parts up front, and couldn't trust the stock Cannondale stem and bars. Also, the stem is tuned with ti bolts as well. Weight savings maybe a mere 30 grams or so.
However, for riding about off the track i wanted a lighter combo so i have a t2 wing mated to a ritchey stem. The cow-horn style bars and carbon stem are probably close to half , maybe even a third(remember I'm guessing) of the weight of the track set up.
As for the wheels...well, i don't have any. That's my secret for building up a less than 10 pound bike.
Well, actually, i just haven't decided on some hoops just yet, still eying some 1170g American classic tubular's. Otherwise, maybe I'll build something else up from scratch.
Last consideration are some mavic ellipse simply because i can get a good deal on them and i really want to ride this thing!
However whatever i do, i'll probably save a pound or two over the stock Alex formula wheel set.
(500 buck)
tires- my trusty Michelin pro 2 race tires at 220 grams a piece.
(35 bucks)
Math time class
frame- initally 1400
final weight after tuning, swapping seatpost collar and headset-1376
fork- 300
seat-post-150
saddle-120
crank-600
pedals-230
stem-135
bars-400
wheels-1170
chain-500
cog-150
tires-440
estimated total- 5,436 grams
basically 12 lbs flat. theres a few things that force that up, a lock ring, inner tubes, grease, etc, maybe gaing another pound or so. Ultimately, 13 lbs on a ride-able, race-able track bike, thats damn impressive.
As for the pics, i may just wait until its all finished, or until i get a gram scale where i do a detailed build up.
Bottom line, 13 pounds, it's do-able.
