how can you tell how much your bike weights? i'm very curious as to how much my sirrus weighs.

Stand on your scale, weigh yourself, note weight. Pick up bike and weigh again, note new weight. Bike is the difference.

humm.. that's a good idea. i was thinking maybe i can lift up the bike and left it up so rear wheel rest on the scale. i'll have to try ur way as well.

I'd say that's not going to be all that accurate honestly. Unless your scale happens to be fine tuned to perfection, I don't think it would give the most accurate reading. I'd probably go to a post office and have them use one of their hanging scales.

woohoo... another bay area rider!
hanging scale? humm.. if and only if manufacturers list the weight of the bike in their spec sheets.

Email the manufacturer and ask. I did for a bike I was looking at and got a prompt reply.

a hanging scale is the most accurate way to measure your bike.. We have one in the LBS, one that can go up to 20kg, and very accurate for measuring weight of finished bikes. For components tires, we have a 5kg hanging scale w/c is very accurate.

here is the reason they (specialized) don't list the weight in their spec sheets:

``Understanding that many of today's consumers are weight-conscious when it comes to their bicycles Specialized stands by our policy to not record or provided weights for our bicycles. Our frames are among the lightest in the market and still carry a life-time warranty--which many manufacturers have abandoned. We want to make our bicycles light weight, but we want them to last a long time as well.''

i personally find this frustrating and i know many other people who do as well. i want full information for something that costs hundreds or thousands of dollars!

If your employer has a digital shipping scale, and you can convince them to let you use it, here's how I weighted mine:
Put the scale on the floor.
Put two small pieces of wood or a similar item, on the scale (this will prevent the tire from rolling)
Zero the weight.
Put the rear tire on the scale between the two pieces of wood.
Hold the bike upright, balancing it the best you can, and read the weight.

yup, that's what i found to be frustrating as well. cuz now i'm shopping for a hardrock sport 17" and since they are backordered now, i looked into a trek 3700, and it's heavier than the hardrock. it'll be easier if they just provide those info.

yup, we have a digital shipping scale at work. i think i'll have to do that next week secretly.. hehe

Lemond doesn't provide weights either....

The bathroom scale is the easiest and it can be fairly accurate. Certainly to the pound. If you're looking for accuracy to the ounce, take it to the LBS.

yeah not showing the weights is annoying. like Cannondale. they have a spot for it on their website but they just dont fill it in.

I tried to do the weigh-yourself-holding-the-bike thing, but I'm not exactly light, and my scale bottomed out But we have a new bathroom scale now, maybe I should try that.

yup yup.. going to try the bathroom scale 2nite, and then to my work's digital scale next week. i'll post up my results. perhaps someone should whip up a site where this weight spec can be inputed.

And if they do, don't believe it. You need to weigh it yourself.

LOL.. that's true.. cuz it might not be 100% accurate due to marketing purposes.. haha

weighed WITH the 2 full water bottles, tools &spare, cell phone, etc. and 6 lbs of sweat soaked 3 layers of clothes because its still only 36 degrees at 5:30am + my 185 lb frame, CO2 cartridge, spare, rear blinkie, front headlight. ... . .

My hardrock sport 17 is around 30.3x lbs... i dont remember the last digit. its a bit on the heavy said... i dont mind really since im not shelling out $2000... my friend is looking at a trek 4300 and its around 29 lbs IIRC

humm.. interesting. i would think the trek 4300 will be heavier than the hardrock.. but humm. interesting.

I just used the bathroom scales to weigh my bike but instead of standing on the scale I just balanced the bike on its rear wheel till you are barley touching it.

The Hardrock is about 2-3lbs heavier than the Trek... the stem alone on a Hardrock weighs like a pound or more. Just looking at the tubing you can tell the Hardrock is going to be heavier... much more metal in it than the 4300. Not a huge difference though.

No junk bikes though

K so if you wanna weigh your bike go to your LBS and ask them nicely to use their scale... 99% of LBS's have a good hanging scale.

My bikes weigh much less than I do. That's about all that matters to me.
