I am a climbing specialist that has aspirations of sub 56 on Mt Washington this year. I have decided to build up an “ultra-light” for this race as well as a few other uphill time trials that I will do this summer (Whiteface, Mt. Ascutney, Bolton Valley)
I wanted to get this groups opinion on my component spec, as well as answer a few of my questions.

Frame: Something in the 2.4 to to 2.8 lb range. Obviously the lighter the better, but price is more important here than weight. This bike will only be used in a few races so I can’t justify anything really expensive. Here is my list:
Cannondale CAAD4-5-6-7 (CAAD4’s can be picked up for around $300! 2.8lbs)
Trek OCLV 2.4lbs but ~ $800
Fuji Team 2.4 lbs $???

Fork: Reynolds Ouzo Pro (465g)
Front Brake: Cane Creek 200SL Caliper (125g)
Stem: Ritchey WCS (124g)
Bars: Ritchey WCS (225g)
Seatpost: Thompson (195g)
Saddle: Selle San Marco Aspide (160g)
Rear Derailleur: DA 9 speed (195g)
Chain: SRAM PC-99 (296g)
Right Brake/Shift Lever: DA 9speed (~215g)
Left Brake: I just need a hood on this as there will be no rear brake. Suggestions?

Now here is where I have most of my questions: Bottom Bracket, Cranks, and Chain Rings. I was thinking about saving some cash and just pulling my FSA carbon cranks off my road bike and putting them on this when I needed it. But then I thought I could save some weight and use track cranks instead. I will only have a need for a single chain ring with no font derailleur. Could I use track cranks with a single 30 tooth chain ring on the front? What would be the lightest crank setup for this bike? Almost all of the climbs have sections over 20%.

These will all come off my road bike for when I use this one
Pedals: DA SPD-SL (277g)
Cassette: DA 12-25 (172g)
Wheels: Zipp 404 (1283g) I would like the 303’s (1124g) but those might have to wait!

So what do you think? How light do you think I can get it with this component spec?

Butron,

In the quest to be light Thomsom posts are over engineered try http://www.ax-lightness.de, www.schmolke-carbon-titan.de/ or www.boldprecision.com/.

Schmolke can also help you with bars and Bold with squewers.

With the chain the 89 is lighter (has cut out side plates) unless you are getting the new hollow pin one.

As for track cranks - they wont fit a 30t ring, smallest is a 42t.

Topolino (total wheel weight 1390 !) But, lots of thick spokes watch out for the cross wind !

Spinergy
vectran enabled - SPINERGY Tillium Carbon
1500 wheels climb like a bat outa hell. (I use Spinergy xaero lites and they absorb shock so well I can inflate my vittoria open cx's to 137/145 and they go uphill like crazy without binding. (now if I can do anything about the engine !)

Have a riding buddy who just got a Fuji. Pretty nice bike for the money. At 2.4 lbs its probably your best bet. You could loose at least 1/4 lb in the fork though. The Fuji frame should come with a nice light fork. If not go for the Easton EC fork or a Look HSC. You can usually find the HSC's on sale on the net.

My recommendations...

Zipp 303's...all the stats I've seen say they are lighter.

www.carbonlord.com, sells DA/Campy compatible carbon cranks on eBay for $175. I use them with Speedplay X-1 pedals and love them.

USE Alien carbon 250mm 27.2 seatpost 128 grams (about $100 eBay)

ITM "The Stem" w/ Easton EC-90 bars

Use a downtube shift lever for the big ring, not STI.

WRComposoti makes some light stuff. I ordered a fork out of the UK from LLyod's Cycles with no problems on a Visa Card.Part What I have.. Upgrade Difference

How about the new Scott C1 Team Issue carbon frameset? 890 grams for frame, 300 or so for forks. Very nice, £1500 total though.

FRM has also quite light stuff: BB 125g! ISIS Deda magic seatpost is light 165g/290mm and costs just 90€. For the cranckset: use a lightweight MTB cranckstel (FRM, tune, Storck - if you want to pay for it) and take just 1 chain ring with track bolts.
