It's a combination. Careful component selection, without breaking the bank, can make a big difference.

Some vintage components are surprising light, Campy NR & SR derailleurs are light. Record seat posts are boat anchors. Dia Compe brake calipers with alloy hardware are very light. A lot of C Record is heavy.

Regular cromo frames are relatively heavy, 531SL, SV980 and Tange Prestige are lighter.

Raleigh Pro Track:





18.8

Frejus:





24.0. Compare to Torpado with steel cranks and three-piece steel-barrel hubs. (Obviously other variables also.)

For the sake of accuracy, one would need to empty the container and weigh the empty container, though .7 pounds seems a bit heavy for such a size plastic bottle, it clearly weighs 'something'. I do, however, note the statement that only 3 gallons of water was weighed, no reference to a container. Pictures or it didn't happen!

PS: I just realized that 'calibrated' implies, in this case, a 'weighing', but perhaps there is another methodology for said 'calibration'.

Indeed.
"Back when" we built three bikes for a customer w/ the lightest framesets available at the time using Alan, Teledyne Titan, and Exxon Graftek as fashion dictated.
All were outfitted w/ Hi-E, Weyless or whatever was most "trick" and light.
None were actually ridden but they were Light and made great static displays.

Takes all kinds.....

Ed. was refering to the digital part of the scale methinks. You need an analog scale to be C&V!

I think you're right. We need a thread, analog vs digital scales, discuss which is more C&V appropriate. Now if I could only find that old analog computer to post messages with . . .

Thank you kindly. Its truly a treat to ride. The better word is 'magical'. Credit due some of our fellow forum members in the acquisition and many parts. I often remind myself that we're just temporary caretakers, honored to be and only hope the next appreciates this stuff.

Getting back on topic of total weight. When I built this one up the goal was not seeking minimal weight but the end result is pleasing. Regardless of weight, I do like the old school style 'hot-rod' performing parts. Hard to explain but I'm gravitating to 1950's - 60's stuff. Could say I'm fortunate to have modern too, but once you get miles in on this era bikes, they have a very rewarding feel. The sum of parts don't have to be perfect like clickity index modern or overpowered brakes. As long as they work including the wet plus have modulation, I'm happy. To me, it adds another element and challenge to a ride. There's lots of old parts out there that are amazing light. The old Swiss made Weinmann stuff is really cool, especially brakes and levers (a bargain to be had as well). This particular bike has a Weinmann cottered crank in aluminum and MAFAC Racers.

There's still things on it considered rather heavy but I prefer them over the lightest. How could I not resist that saddle or steel hubs? Two little things left is swapping pedals to period and lighter Marcel Berthet M23 and if lucky, hope someday to find a TA Specialites alloy front brake cable hanger.

Be careful. They are cheap to buy, but can be costly to own.

OK, details. I took a 5 gallon bucket and a web strap and hung that from the scale. Hit the tare button which zero'd the reading. Added 3 gallons of water ("a pint's a pound the world around") to get the scale in the range I was planning to use. It read 24.73 pounds, ergo, .73 high. Weigh a bike, subtract .73 from the reading and proclaim "good enough".

Now the engineer in me thinks I can open the cheap plastic box and find a pot on the board - said pot being a bias setting that I can fiddle the error out with. Wishful thinking eh? Then again, MAYBE it didn't happen given the total lack of jpg evidence.

Back to our regularly scheduled thread now.

What did you use to measure the water and how accurate is it?

1986 Centurion Ironman. Not period-correct. 19.37 lbs. I thought it was less, actually, but didn't build it to be light, anyway.
Great Chinese scales, under $5 shipped. Weighed 19.56, and as the weigh-ins went on, every bike got heavier and heavier.



Both of the C&V's are regular riders.


Getting to non-C&V:
2004 Cinelli XLR8R-2: Carbon frame/fork, post, wheels, bars, crankset.
A little heavy on the saddle with a SSM Concor Lite (modern version)
Stem is scandium, so lighter than carbon. 15.31 lbs, could hit UCI 15.1 w/a saddle change.
Not bad for 2004 with Columbus Airplane aluminum dropouts, fork ends.
Ridden less because it needs a thorough cleanup, tough on a soft-touch finish.

2014 Wraith Hustle: Columbus Life steel frame, Columbus FEL carbon fork.
Thomson seatpost, carbon cranks, bars, Alloy stem, Prologo Evo saddle.
Carbon wheels, but it could be lighter if I wanted it to be. 16.34 lbs.
Ridden less because I scratched a decal in transport, and I'm still bummed.

23.3 - CIOCC SL - full C-Record/Deltas, Mavic Ceramic rims - real pretty but heavy
20.7 - Bianchi EL/OS - Athena 11sp, TI stem/post
19.8 - Cinelli SL - Record 11sp carbon, Shamal wheels - modern components made it 3.5 pounds lighter than the SL CIOCC - same seat/post/pedals
17.5 - Cervelo R3 - 105/Fulcrum 3s - obviously not C&V, but that's what you get off-the-rack these days

Unfortunately a US pint is only "about a pound". it's 1.04 pounds, which makes 3 gallons weight 24.96 pounds, so you should have added .23 to the weight instead of subtracting .73.

And more importantly, was the error a linear value or a single constant offset? Did you use heavy water?

I'm always amused by weights for bike without pedals. You can't ride without pedals. Next time I weigh a bike I'm going to remove the pedals and the saddle and the chain and the freewheel and the brake calipers. That should bring the weight down.

It's all relative, and arbitrary, i.e. UCI.
