Now I know why a lot of people list their bike weight without pedals. I'd be down to 16.7lbs of steel :eek:

Office Depot is where I got the luggage scale.

Picked one up at TJ Maxx and weighed my 29er. 32.3 lbs. Oof. It's supposed to be a tank though so I can live with it. Also turns out my LBS's scale was inaccurate :(

How do you know which scale is inaccurate?

I weighed my tube, tire, and front wheel individually on my digital desktop scale, then weighed them all together on my luggage scale and the luggage scale read +2% over the desktop. My bike on their scale vs my scale was off -8%. Since it was much closer to the desk scale I'm assuming the scale at the lbs is wrong.

All measuring devices have inaccuracies, except for those designated as standards, and even those have specified uncertainties. When you look at the packaging, they usually list some unit of uncertainty (often in units like "+/- 0.1 grams") but that assumes the device is properly calibrated to begin with, which chances are it's NOT. Calibrating a device boils down to comparing it to a known standard, and adjusting it to be as close to that standard as possible. Once properly calibrated, the uncertainty starts to have some meaning.

Everything in our lives is subject to this. A great example is the oven in your kitchen. Just because the knob says 350 doesn't mean it's actually 350. Or maybe you have a digital version with buttons and a thermometer built in? Just because the display says 350 doesn't mean it's 350. One way to "calibrate" it then is to get an external thermometer that you trust, and measure the heat. Keep adjusting the temperature until the thermometer actually settles to 350. Now you know what to set your oven to!

The other thing to consider is that some devices are less accurate at certain ranges than others. For example, your scale could have a range of 10 grams to 1000 grams. It could be well calibrated for something around 500 grams but the further you get away from that point the more error there is. Using the oven analogy, just because you set it to 380 to get a true 350 doesn't mean that you set it 30 higher for all other temperatures. So it's best to calibrate it at various points along the range and interpolate between them.

I bet no one read this wall of text :)

Interpolate. Got it.

My leader 725 is 19ish. Maybe a tad lighter.

With fenders for winter it's probably 22-23.

My school's gym is right in my back yard. I'm tempted to go measure some free-weights as reference points.

Go to your physics building and find a lab with gram masses in it. Just say you are testing your hypothesis and they'll leave you alone.

my 721 is somewhere around 22 with my rear fender on. Time to get a non-tank wheelset

Caad9 17lbs. Pake 19...maybe 20lbs now. Columbia hybrid beater(40ish lbs)...priceless.

S2 is around 15.6 and will be around 15.3 after I change the pedals tomorrow (Look Keo Carbons ftw). After I build up the Leader I'll look at trying to get it to 14.X :D

Good luck with that.

People that get sub 15 lb steel frames ride tiny frames with the highest grade steel you can get. If you do manage to get it with a 722ts you're probably going to spend 20x the cost of the frame.

I meant get the S2 sub 15lbs, not the Leader...

Come on, guys. Have some faith in my intelligence here :/

:lol:

13.1 lbs with out the pedals, 13.8 lbs with the pedals, 56cm frame size

MY: 2011 Giant Seek 1 with disc brakes: 27lbs.
1977 Peugeot PX10LE: 27lbs.

They have this new stuff called carbon, I hear it is lighter than steel. Can someone please confirm this?

Thanks

You can buy a sub-15 lb complete, including pedals and bottle cage, 20 or 22 speed steel 58cm road bike if you have the money. Figure 7-12 thousand dollars.

Probably slightly cheaper if you go fixed or single speed and/or plastic.

road racing bike (alu frame): 16.5-ish
road training bike (steel): like 22 or 23 or something.
fg (steel): never weighed it, but my guess would be like 18.5 or so.

I just got this for $60 and it weighs about 27 lbs. Of course it didn't shift at all and the freehub pawls were all stuck when I got it but it's getting better every day. Seems like most of the weight is in the ass end so I'm gonna put my Campy/Nisi tubular rear wheel in there, UN-73 BB and Chorus cranks then we'll see how she does.

That is one very, very nice bike.
