Weight of a bike

Underscore

Giant SCR1 : 9.8kg/21.5lb

(Is it cheating to use google instead of scales?)

According to Google:

Giant Defy 1 (Medium - which I have - not pedals): 8.90kg/19.1lb
Time ATAC ROC pedals: 0.384kg/0.85lb

So total bike weight: 19.95lb

Rider's weight: *mumble*mumble* lb

My (2008, carbon) Focus Cayo Expert with pedals and saddle is 18lbs. My (2009, steel) Bob Jackson Vigorelli fixie-wixie-woo (with saddle & pedals) is 19lbs.

My (2005, alloy) Trek 1200 with pedals, saddle and lights (and quite possibly lock, though I can't remember) is 24lbs!!

Well, using a spring balance with a hook is probably the best way, but you can do it reasonably accurately using a set of bathroom scales.

A) Weigh yourself.

Weigh yourself again while holding your bike off the floor.

Subtract A from B. Since you're using the same pair of scales both times, it shouldn't really matter if they're a little out, as all you want is the difference between the two measurements, not the absolute value.

If you want a really light bike, subtract B from A.

According to my research the Maxima weighs in at about 14lb...

This seems too light, but is based on finding out the weight of all the components and adding on half a pound for the seatpost which I didn't know the name of and a pound for error, but there's still some margin for error, definitely...

I'll weigh it soon, promise!

However, I weigh rather a lot...

EDIT: huh, well it's definitely lighter than Greg's, so maybe I'm not far off, whether or not it's a pound lighter....

This tends not to work. For the weight weenie market, weights are published, but the weight of components can vary and you can be sure that if they make 200, they'll find the lightest one to publish the weight of.

Frame manufacturers do silly things like publish weights without paint, or frame bolts, or seat clamps definitely without headsets or bb's. Wheel manufacturers omit rim tape, tyres tubes (obviously) or even skewers.

Even the groupsets omit the weight of cables and housing.

Did you include your computer?

OP: DDD, everyone goes through a w.w. phase. Don't sweat it.

Why are so few bikes sold giving weight stats, it's fairly important, even to your average commuter :roll:


I just noticed the post above ... that may be my answer :oops:

Eau Rouge

I missed a trick here. I should have done the bathroom test with the Le Roi while I had it.
The Mortirolo, complete with rear light, pedals, saddle and saddle bag with stuff in comes out at a whopping 9.5kg (21lbs)! but thats with the Mirage groupset on it. :oops:

Oh yeah. 5:07pm, anyway. In my defence, I'm distracted from reading any of lost_in_thought's post because I'm captivated by his/her avatar.

Internet weights are notoriously bullshit, you need to get it on an accurate set of scales if you really must know. A lot of people here claiming outrageously light bikes, be interested to know how many of those are actual weighed with a set of scales weights or guesstimates.

Hers. And yes, it does look like her head is about to a) Pop or b) open up into a lovely flower.

That's what you meant, right?

Try getting off before said weigh-in.

My Jetstream is a touch over 23 lbs at the moment- weighed it at 11kg, but I've now got slightly lighter Marathon Racer tyres on it, so in metric about 10.7 kg. It was just under 20 lbs when I got it, but then added mudguards, Ergon grips, Marathons instead of Stelvios, computer, and last but not least a SRAM DualDrive hub gear- big heavy lump of kit, plus shifter, stronger rear wheel, etc. Wish it was still the stock weight, but the extra gear range comes in handy, particularly as you're not supposed to stand on the pedals, puts too much stress on the long stem. With 22" I can just sit and spin, even up Ditchling Beacon. Cadenza is allegedly heavier, doesn't feel it to me.
I don't need to lose weight.

My FCN 10er weighs in at a hefty 29lbs, and proud of it! About as much as a decent sub-£1k hardtailed MTB, but on 29" wheels, which means that when you get it up to a good turn of speed all that momentum turns it into a wicked projectile!

"lol"

Niff Niff :evil:

bomberesque

I'll bet my commuter weighs nearly 30lb

Cotic Roadrat with drops
Brookes B17 saddle
alfine hub
Dyno front hub & assorted light gubbins
punctieproof touring tyres
sks thermoplastics
full touring rack
BB7s

It did have a complete anchor of a 1500gr steel fork (not the cotic one, an old Identity Tuning fork) on it but I swapped that out for a carbon one that came spare when I built my new SS MTB up and that's dropped >half a kilo.

But my biggest problem is wind not hills (I commute in Flanders, which is flat as a witch's youknowwhat) and anyway once it's up to speed it really doesn't feel the weight it is.

My new SS on the other hand I think will be 18lbs or less :-D

Best way is with a hanging digital scale (as you would use to weigh a fish you'd just caught).

Second best way* is to weigh each bit using digital scales as you build it. Write the weights down and tot them up.

*Only a really sad git would do that. <cough cough>

Stand clear. I'm a scientist.

One point I used to make to students was that the mere provision of a digital readout does not make the measurement more accurate, if the measurement is fundamentally analogue.

So the best way would be to first calibrate the scale using an object of known mass (the mass being approximately the same mass as the anticipated mass as the bike) and then weigh the bike. Although the scales may have a non-linerar response, the error this introduces will be minimal if the calibration is conducted as close as possible to the operating range of the scales which you wish to calibrate.

Mmmm. This World of Warcraft I'm playing on the other screen is thirsty work. I'm off to get some H2O (with trace concentrations of inorganic salts).

I need a heavy bike to support my substantial weight

Ah, those were the days. Had a level 60 undead priest back in the day on Bloodscalp PvP. Those says of waiting around for hours trying to assemble a full 40-player raid group for Onyxia or Molten Core, endless Blackrock runs trying to get everyone keyed up for Onyxia i the first place.

Awesome game, although I found levelling and the 5-player instances so much more fun than the 40-player end-game crawls that went on for hours on end. Being in on server-first kills was fun though.

ObOnTopic: my commuting bike weighs 24lb, maybe half a lb more.

Actually, I don't really know too much about World of Warcraft. Just saw a South Park about it, figured it was qualitatively similar to dungeons and dragons, surmised that it probably attracted a similar demographic, and placed my foot firmly in my mouth.

fossyant

My new fixed, with pedals, computer, guards and 2 x bottle cages weighs a smidge over 8kgs......

vinnn

My Cannondale Synapse Carbon all in is 19lbs...
...well it is a triple!

UnworthyPapaLazaru

My new Boardman Team Carbon is 17.6, excellent for a £1000 bike.

Deadeye Duck

My current commuter weighs in at a lovely 42.2lbs... 8)

Mine is weighed on digital calibrated hanging scales. I have also weighed individual components.

I have to much time on my hands some days. :roll:

See my first post of the link to Weight Weenies website. My Bike is heavy compared to some of the madness there.

Oh, for goodness sake! I suppose you're going to tell us all that calculators and computers merely give the illusion of accuracy by dint of their digital readouts. :shock:

Scientist, schmientist.

You'llbe trying to tell us that your cycling computer has a needle to point to the speed next, I'll wager.

Fair play.

However, it does make the measurement easier to read. Personally, that's why I use 'em.
