    With a accurate Hanging scale.

    I personally don't have one nor have access to one. I just have a spreadsheet of the parts of my bike.

    With this - I've got one and it is VERY nice. Just clamp the silver rod (dummy seatpost) in a repair stand and weight just about anything.

    fish weighing scale, any fishing/hunting/sporting good store should have one. I think Walmart might carry them as well.

    I have done the same as bike_freak. I am currently rebuilding my bike and have setup a spreadsheet with individual parts. That way if I change individual parts, I can easily work out the overall change in weight.

    hop on the bathroom scale, get my weight, then lift up the bike, and see what the difference is.

    that spreadsheet weighing

    is complete bs! put the bike on a calibrated scale, not a fish scale.
    the inaccuracy of those fish scales is huge. my trek fuel is a legitimate
    22.4 lbs on a CALIBRATED scale, but on different hanging scales i have
    seen variations of +/- .5lb

    It's pretty hard to get excited about a scale, but this thing is pretty sweet. I weighted my new road bike frame, and found out a carbon Look 461 is 200 grams heavier than advertised. Maybe because I ride a 61cm...

    Did you know that my briefcase weighs 17.83 lbs?
    My Raleigh three speed Sports weights 34.56 lbs.
    My Miyata 26" touring bike weighs 28.28 lbs.
    My Ridley Crosswind with a full luggage seatbag (two jackets, one pair arm warmers, one pair leg warmers, three tubes, one pair of gloves, a pair of tyre tools, one utility tool, a Payday candy bar, GU bottle, and etc in one large bag) & water bottle, with Ritchey Comp wheels and Speedmax 700 x 35 tyres wieghs 28.57 lbs.
    My Ritchey BAB Road Logic wieghs 21.4 lbs.


    The bathroom scale and excel spreadsheet are worthless compared to this thing. I tried both and always was off. The spreadsheet was closer, but I'd rather work on or ride my bike than sitting in front of the computer. My work kept getting pissed at me for hogging up the postal machine to weigh stuff too. My bathroom scale was only accurate to 1/2 pound. If I want to put one less tire lever or tool in my sabble bag, I can see the true weight savings in seconds now....

    I have three digital scales I use. A pair of Pelouze desktop scales, one rated from 0 to 5kg in 5 gram increments, one from 0 to 2.2kg in 1 gram increments, and a noname branded hanging scale rated 0 to 25kg in 10 gram increments. All three also have pound and ounces modes (with various increments) but except for the hanging scale I never use them anyway except metric. The hanging scale lists it in pounds and ounces in 0.02 pound increments. The noname brand one comes from the same manufacturer as that yellow one above, but skips on the metal tube to clamp it into a repair stand. No biggee, I prefer hanging it from a ceiling hook anyways.

    The problem with the spreadsheet method is people rarely remember to weigh any grease or oil they apply to the bike during the build. Or things like cable and housing endcaps, or cutting off excess cable/housing, etc. Or adding zipties. Small changes in weight, plus and minus, that can add up to an ounce or two overall.
    I don't post to generate business for myself or make like I'm better than sliced bread

    Scales are all Different

    22.4 lbs on a CALIBRATED scale, but on different hanging scales i have
    seen variations of +/- .5lb
    Weight per my spread sheet 9841 grams ~ 21.70 lbs.
    Hanging digital @ work 21.85 - 21.90 lbs was going back and forth between .
    Bike Source 21.60 lbs
    Adventure Cyclery 21.50 lbs both the shops have newer hanging produce style scales
    So if it's not a certified scale you really can't say what your bike weighs they are all a little off. As these weights were all done in two days!

    Actually it matters a great deal.

    Accuracy is your best friend when you have gone to a great tireless effort to get a bike below a certain weight. Who wants a scale that is 1Kg off if you've just broken your back spending heaps on light parts.

    My spreadsheets match my scales.

    I have an inexpensive digital fish scale that is quite accurate. It is within an ounce of my spreadsheet totals which I make using a MyWeigh 6001T. I have verified the accuracy of the MyWeigh. Every scale is CALIBRATED, but not every scale is accurate.

    If you are saying that creating spreadsheets using published weights is BS, I would agree since manufacturer weights are generally optimistic. I've found those on the Weight Weenie website to be pretty good if you are careful to match the part exactly. Sometimes the descriptions on the WW website don't make that possible though.

    Thats a good point. It never ceases to amaze me how some calibrated scales are very far from accurate.

    What is holding the scale up?

    Maybe you should get your scale calibrated

    If you have a gram accurate scale for weighing individual parts go buy another one so you have two (these things are not expensive)

    Take the tires and tubes off from your wheels (you can weigh these seperately later)

    The rims give you a solid flat surface with which you can stand the bike upright without the need for support.

    Put your tireless and tubeless wheels back on the bike.

    Spread the two digital scales apart, place the front wheel on one scale and the back wheel on the other one.

    Add the values up, weigh the tires, add these in.

    Job done, whole bike weighed, gram accurate.
