Especially in the lower end of the price range, I'm seeing bikes that seem to range from 21lbs to 30lbs. Bikesdirect.com send me this rule-of-thumb:

Road bikes all weigh very close by Shimano group used:
Shimano 2200 bikes - around 23
Shimano Sora bikes - around 22
Shimano Tiagra bikes - around 21
Shimano 105 bikes around 19
Shimano Ultegra bikes around 18
Shimano DuraAce around 17

This would put, say, the Schwinn Fastback Sport (~$450) and bikesdirect.com bikes in the $4-500 range at around 21-22 lbs. This is also the weight of the ~$1200 Jamis Nova and the ~$3000 Giant OCR C-1. Yeah, there's more to a bike than it's weight, but I don't want frills - just a few gears and fun (my lumbering 29lbs utility bike is NOT particularly fun!). If I'm buying on-line, what's the best way to keep from getting stuck with a 27lbs dog?

There is no comprehensive list. You might check weightweenies, but their listings are a bit dated.

Thanks powpow. Yeah, WW is good, but doesn't have full bikes - I realize that it's hard to keep up! Sometimes folks post weights on road**************** reviews, but who has the time to sift through the reviews! Oh, and here's one LBS who is kind enough to post weights of their bikes: https://www.thebicycleescape.com/bicycleweights.html

There are too many variables, like wheels, saddles, bars, pedals, etc.

Be careful with an online purchases. Get a list of all components. If you want Ultegra, make sure that the brakes and cranks are Ultegra; not just the derailleurs.

Like GP said, there are too many variables to make a good list. I think the list that BD gave you is a bit optimistic, and a 105-equipped aluminum bike with average wheels will probably be in the 20-21 range. If I were you, I would go with something like that. 105 is pretty good nowadays. If you can afford Ultegra or Dura-Ace, even better. You might also consider SRAM Rival, which is lightweight and relatively inexpensive.

I think that BD list is nonsense.

THe only thing that will be of help to you is to either get actual weights from similar bikes (see below). If you do that, you really have to get into the gnat's ass in detail to make a good comparison or estimat.

Or go to www.weightweenies.starbike.com and look at frames, components and add up the weights.

The reason those lists - and anyone else's bike's weight - are pretty much worthless is that there are four main ingredients, only two of which are common to "similar bikes"

1-Frame - and possibly fork if it's standard
2-Component group
3-Wheels, TIRES and TUBES: These three items can easily make a full 2 pound difference about half of which can be in the tires and tubes alone!
4-"Other parts" - bars, stem, seat post, saddle, pedals: each can make a 1-3 ounce difference, easily 1/2 to a full pound in aggregate.

Add to that, if the bike has an upgraded fork, that can also make a 1/2 pound (200+ gram) difference.

The first two can be pretty readily genearlized and are probably the only common factors to the list that BD published and what you will be able to find comparing bikes similar to what you're thinking of.

But the second two categories can easily make a pound or two difference ... EACH. Seriously, changing wheels, tires, tubes and all the other parts can make a 2-4 pound difference. Thus the "18 pound Ultegra Bike" could easily be 21 lbs, and will often be.
