Does this sound right to you?Spoke Wrench

Took my wife's bathroom scale downstairs to weigh my bikes. Now I'm depressed.

My Quantum Race, for example, size 57 with Vector Comp wheels, Thompson seatpost and stem, Kestrel handlebar, Body Geometry Pro ti saddle, SPD 747 pedals and a seat bag containing one inner tube and one co2 inflator came out to 20 pounds. Not bad, but not exactly bragging weight.

Santana Noventa tandem - 40 pounds.
Bridgestone RB2 105 triple - 25 pounds.
Porsche Bike S hard tail mountain bike - 28 pounds.

Do these sound like reasonable no BS weights to you or should I go looking for a more accurate scale?
It sounds pretty close........Dave Hickey

I weighed my LOOK 241. It's full Dura Ace, Open Pro's, Cinelli Solida Bar/stem, LOOK pedals, and seatbag with tube and CO2. It came in at 19.5lbs. Most advertised weights don't include pedals or seat bags.
Or bottle cages ;O)Pecos

what size is your 241?Beaver
Jul 5, 2002 8:23 AM
My 54cm KG 241 weighs in at 18.5 with pretty much the same setup but with Ultegra and without a seatbag. My tube and CO2 go in my jersey pocket. Oh and thanks again for that jersey, but wouldn't you know I got chain grease on the back when I was changing out a tube on the side of the road.

Mine's a 50cm. I've only weighted it on a bathroom scale. I'm not sure how accurate the scale is.
I just weighted it on my dock scale at work....Dave Hickey

It weights 19lbs. The scale rounds up after .5lbs, so it weights between 18.5 and 19.5lbs.
I should have said "weighed it".. sorryDave Hickey

Interesting. Makes me wonder just how accurate the scale is at my LBS.

Well, I would pretend to weigh the bike on another scale and tell the wife that her scale is wrong and your bike is a lot lighter than thought. This will suggest to her that she is lighter than she thinks and put you in the good books for the weekend.
Excellent Idea! I never thought of that. (nm)Spoke Wrench

My Canny (56cm) weighs around 17.5 with pedals, 2 cages, and computer mounts. I would guess that the cages, pedals and computer stuff adds around .5lb. My scale seems pretty accurate (matches the numbers from a medical scale from recent doctor's visit). The bike is full DA with special K's, Alien CF post, Terry X-Fly, ITM260, Deda Zero, Axial Pro's, Michelin tubes. I did not have the my saddle bag, etc on when I weighed it.
I would guess is you are riding Look/Time (mine are X1's) and have the typical crap in your saddle bag you could easily add 700-1000gr (~1.5 to 2lb) to the actual weight of the bike.
Of my bikes that surprised me was my Pisgah which was only 1.5lbs lighter than my Jekyll. That was depressing.
As you well know, published weights do not include the every day stuff like pedals, cages, etc. Probably do not include things like bar tape, plugs, magnets, etc. either.

I don't think the weights sound too out of line. I know I'd very much like to ride without a seat bag, frame pump etc. I guess I'll have to wait for a sponsorship so I can have a personal support vehicle. (yeah right). Doesn't sound like you've got anything to jettison on the Klein.

Suggestion: Throw some barbells on the scale since their weight is known. I would think that would tell you how accurate the scale is.

Bigger bikes weigh more. A 57 is not huge, but still heavier than a 54.

Those numbers sound about right.
yeah...try a 62cmColnagoFE

I think if you are much under 20 lbs with a frame this size you are getting pretty light. No way I'll ever have a 15 lb bike unless I shrink.
sure you canJekyll
Jul 5, 2002 8:51 AM
All you have to do is give up comfort, durability, and your mortgage payment.... The only shrinking required is that of your bank account :-)
even air in tires weighs .... 115psi x 2 = 11.6 gramsSpirito

20lbs sounds reasonable for a bike of that size with all the riding bits in place and for the spec given.

as a matter of fact most should be happy with that figure. i had a 17lb bike - but if i planned to ride it more than 10 miles its weight (bottles, water, spares, tools, pump) would rise to 20 lbs.

no manufacturer that i know quotes actualy weights as would be ridden which makes me even less keen to believe them. ive stopped weighing bikes and wheels and have solely bought or used quality/long lasting products and whilst i suspect that my rig might be heavier i dont feel any slower. i am however spending a lot less.

Well now that you know the weights of your bike are you gonna ride slower? I doubt it. I think people must too much stress on a few pounds. I'm sure if you are a good rider you would ride just as well on a 30lb bike as you would on a 16lb bike. Its not all the bike its mostly the engine

This is the slippery slope logic at its extreme. 14lbs is a big difference! That's not to say Lance on a 30lb bike won't kick my fat ass, but that's definitely not a negligible weight difference.

haven't weighed it lately, but with cages, record profit pedals, SLR saddle, saddlebag with a park tool kit, and open pro 32 w/ revs wheelset...it weighs around 20 lbs.

Vector Comps aren't exactly light wheels... and your 747s weigh how much (aren't they double sided)?

Seriously, your scale could easily be off by a fixed amount, like a pound or two, just as your weight can fluctuate by that much between your doctor's office and home.

I've vowed NOT to worry so much about weight on my bike... it is like a weird form of bike anorexia... where does it end? Are we adding how many grams of lube are on the bike? How much the spoke magnet weighs? The valve caps? Bar plugs?

I think more bikes are closer to 20lbs ACTUAL weight than most braggarts care to admit. "Spec-ing" bike weight by adding all the manufacturers' posted weights is absurd. You know they sort through parts to find the lightest ones, allow and disclaim that they are accurate to within a given percentage, then take advantage of the margin of error and deliberately post low.

I'll go out on a long ride with two large water bottles. I honestly can't tell the difference between going out full and returning empty, and there can easily be a pound or two of water lost during the ride- not to mention my own body water that is sweated out (it simply drips off of me on these hot days). My point is, if you spent two grand to shed two lbs, would you even notice it?

Unless you are climbing or accelerating, weight doesn't mean much at all. Air resistance is a much bigger villain (you could probably draft as fast on your mtn bike as your Quantum Race).

Not that you don't already know all this, but that is all the self-talk I use to avoid thinking about the topic ;)

I leave most of my brevet stuff, headlight, two tail-lights, handlebar bag and generator on the bike and my times vary only a little over what they are with the bike stripped for action. In fact, last week I hit my season's best for 10k from my house to the top of a 630 foot climb. On the other hand, if I lose 5 lbs, I go faster than sin.
How do you weigh it on the 1'x1' scale???elviento
Jul 5, 2002 9:11 AM
Must be pretty easy, but I just can't seem to figure it out.

Jul 5, 2002 9:14 AM
weigh yourself. then weigh yourself holding bike. subtract your weight alone from your weight with bike in hand. remainder is bike weight.
