In that case, you're not a true WW. (I'm not saying you ever claimed to be.)

Weight-Weenieism should be measured in percent of expendable income per percent of system weight. 20% of expendable income per 1% of system weight. With expendable income of $10k/ year, a 180 lb rider on a 20 lb bike can spend $1,000 to shed 1 lb from the bike without being unreasonable.

NOOOOOO the shimano is sooooo pretty (at least the dura ace one on my 84 team miyata is :D )
there is a a time for weight weenieism and and a time for style...... style should win in this case. :50: :giver:

Yeah, "mass transit."

Probably not. As I mentioned to Larry, you gotta balance weight with ugly. I swapped out my alloy pedal cleat plates for chromed steel because they look way better.

Dude .... when was the last time you caught an airplane downtown to go crosstown?

"Mommy, what does 'Obviously unclear on the basic concept' mean?"

"Shhh .... and don't stare at the less intellectually fortunate."

The comment about the "gas-pipe garbage scow" made me instantly think of the plumbing aisle at Lowe's and whether you could build a frame out of galvanized steel plumbing pipe. Or for the WW among us, PVC pipe. Just curious...I have a friend who wants to know.

The decimal point.

I really like to ski uphill. The snow has been bad off piste this year so I’m slacking, but usually it’s my go to.

My Technica’s feel like cast iron cookware compared to my wife’s Scarpa’s. And my skis individually are only slightly lighter than her pair.

I never thought much about it since we both move about the same speed up and she’s tiny. I only get passed on the skin track by others if I take the ill advised 4th lap.

Then I made the rookie mistake picking up (lifting, not buying) some proper Skimo setups. Holy crap!! It’s even lighter than my wife’s teeny setup and some models even fit crampons (it’s been at least 10 years since I’ve ice climbed, but that’s not the point).

I’m all screwed up. Hot and bothered by my lead cored planks. Browsing the net. Trying to justify the expense.

I’ve already got a titanium spork.

Maybe I can drill holes in my water bottles?

Let's see - I spent about $600 to build up my new mixte about 6 lbs lighter than my last mixte build.

Lighter frame: $175
Lighter saddle: $140
Lighter seatpost: $122
Lighter crank $165

At about 3 lbs difference, that's about $.44 per gram.

No rack, bag, or kickstand - free

It's perhaps another 3 lbs lighter without the stuff inside the bag - a lock, tools, and spares, but less flexible and capable. The 9 pound difference is keenly felt when lifting the bike, but is much less noticeable riding, at least on the flats. But it is still noticeable.

So, more of a weight-beef frank, I think.

Can you express that in a formula?

I think you've stated the answer to the original question!

As someone who knows about how airlines operate....
Yikes!

I'm going to suggest you stay in your lane.

Where expendable income is E, combined weight of rider, bike, and equipment is W, combined weight of rider, bike, and equipment after upgrades is U, and reasonable expenditure is R:

R<E
And
R </= E×((W-U)÷W)×20

“They” sure do talk a lot. :roflmao2:

Is that an Oscar Meyer product?

Obviously a psy-op photoshop job by Big Airline.

Edit: I didn't realize that many folks apparently don't have private bus companies. Around here, taking a private bus is a very popular way to get to work in the city. Lakeland can also be a great way to get to the mall or the casino.

Full disclosure: Lakeland used to have competition (DeCamp), but they went out of business after the pandemic.

Oh, the humanity!

I just got some fat tires and filled them with helium. Hydrogen would be lighter, but then I couldn't top them up at Party City.

Its a love/hate thing. I really hate that what should have been a "reasonably affordable" 16.5-17lb build struggles to get below 19lbs on race day. Of course the stopping power of Campy discs over that the cane creek BRS200sl that I used on my lightest bike is quite the contrast. One is a 2 finger stop on command and the other a white knuckle speed modulator unless you had plenty of room to spare.

Not really comparable, according to How Stuff Works "A plane like a Boeing 747 uses approximately 1 gallon (about 4 liters) of fuel every second. Over the course of a 10-hour flight, it might burn 36,000 gallons (150,000 liters). The 747 burns approximately 5 gallons of fuel per mile" Gonna guess gas costs alone on a trip really skews the trip cost on a bus vs a plane. Not to mention, buses don't have stewardesses, co-pilots, or the same pay scale for a driver vs a pilot.

Sorta like you're not a real cyclist till the bikes on the roof cost more than the vehicle carrying them? You have to blow a certain percentage to show true commitment to the ideals of the lightest weight at any cost.

Takes a little more skill but - drill twice as many holes but only half way. Same weight savings and they will still hold water. But if you reconsider after weighing that water, finishing the holes with a trim knife will be easy.

Well, the SunTour looks NOS and the Shimano looks 35 years old and ridden. The SunTour is also a joy to adjust and dial in. As nice as any post I've ever had. Thompson level. Now the Shimano looks good under the white leather seat it arrived on. Not a seat this old body wants to sit on so I think the post should just follow the seat to wherever.

I weighed the calipers that came on the "new" bike and the Cyclones I was using. "New" (Superbe?) weighs 149 gms (front). Cyclone 156. Good. The prettier ones go on. And I get to do the oh-so-elegant drive-side seatpost route with the sweet housing curve. No markings at all on the calipers. Just like the very rusted ones on the 1st Pro. Levers are DiaComp (but I'll be using Tektros. Horrows! So I gather DiaComp made these calipers in Superbe style. Like!)

Fuel economy for air travel is higher than transit bus, which are quite inefficient. Rail travel is most efficient:

Fuel is a huge cost for airlines. The global airline industry's fuel bill this year is expected to be 32% of their expenses.

What? No e-bike? ;)
