I will make it lighter than air!

I will use the lightest parts i can find. Except for the saddle (I have to have some comfort) and the gears(I have to have enough to get up the hill).

The question is, which frame is the lightest size to size, and I am talking about a 56cm frame.

Looks like I will have to use a Sram Red group and ????. Always wanted to build a 15 lb bike.

There were sub 2-lb frames made from beryllium... Most carbon frames are +/- 0.5 lbs from each other anyway, so you won't save much weight in frame alone.

Also, no complete gruppo is the lightest, so you'll have to mix & match. Titanium cassette cogs weigh 1/2 that of steel, but won't last as long. Hollow-pin chains will help. Tubular wheels are about 1.5-2 lbs lighter for the same strength. Carbon bars and stem, seatposts. Heck, the 150gm carbon seats are actually quite comfortable.

If your goal is to build one up from a frame, that's fine, but it would be less expensive to buy a complete bike. Fifteen pound bikes are offered by major bike brands. They're not inexpensive either, of course, but less money than piece mealing one together-

Litespeed's Ghisallo Ti frame is advertised at 770 grams in a Medium size and 840 grams in ML size. That's 1.69 pounds or 1.85 pounds and they are about the lightest frames I know of that are generally avialable. There are also several carbon frames advertised at <900 grams.

An Easton EX90 SLX carbon fork is less than 300 grams uncut so that about as light as it gets too.

None of these are cheap but, if you really want to have a light bike, start here.

Guy dropped by my shop last year with his Merlin Extralight done up with a custom group. It was about 15 lbs. He said he'd spent about $10,000.

For light weight AND longevity, look at a Litespeed Archon with an Easton EC90 fork. If you REALLY want to spend money, give Crumpton a call.

A beryllium frame? Good Lord! If they ever caught on fire - it would kill everyone down-range. Even some stray dust from it would likely cause lung cancer.

Caveat Emptor!!

Almost as scary as Exploding Carbon frames or Spontaneously Combusting Magnesium frames!

It was super-stiff as I recall. A 2-lb beryllium frame is about as stiff as a 15-lb steel frame, or a 10-lb aluminium or 8-lb carbon frame. Only problem is the $50k entry price... in '80s dollars or about $150k today.

My Merlin Extralight is quite good. I forget the lb on it, but it is not 15 lb. I did not spend 10K on it either, but I have some light stuff and the only thing that would make it lighter is a saddle, TI cassette, and carbon shifters. So perhaps if I did it over I could get there. The addle would be a big thing.

In fact I like the way it rides and it is in contention with my CIOCC for lightest right now.

Building a sub 15 pound bike is easy these days, if cost isn't a major consideration.

The UCI has a regulation limiting Pro Tour bikes to a MINIMUM of 6.8 kg which is almost exactly 15 pounds. Getting under this weight is so easy that the teams can use power meters and other weight adding accessories on their race bikes and still be right at the limit.

Your explanation is clear, succinct, and funny. Thank you.

Well then, I need to get a list of what they are running on their frames just to get started so I can pick my components. Looks like the Lightspeed is the lightest frame so far in 56cm. I was sort of hopeing for a carbon but I like the ride of my TI.

You have the essence of a true weight weenie, I would suggest following neil0502's advice and have a look on those forums (the listings are less helpful imo)
