Weights of bikes

[bikey :)]

Re:

I've found fisherman's spring scales to be dead handy for weighing bikes. I hang mine from the shed roof and hook it under the saddle. It goes up to 25lbs, plus a couple of pounds extra going 'round again', before the scales run out of travel. I get 24 1/4lbs for my 1992 16" Explosif.

They are calibrated badly.

Re:

My 1993 Explosif with full XTR and titanium / carbon upgrades tips the scales at 22lbs 10z or 10.25kg.

The Explosif frame is just shy of 2kg, a Hahanna frame would be about 400g or nearly 1lb extra in the same size. The Kilauea in the same size / year is 225g heavier.

Echoing the other comments, I think the scales are out.

I didn't go to the scrapyard so didn't use their scales but I have some old fishing scales, not cheapo ones and it went 25lb on them. Don't have a camera phone or a way of uploading a pic at moment but as soon as I do I will take a pic as proof. Bike is standard with different rear wheel that is a cheapo with no name rim and quando hub, front wheel a weinmann 2421 not sure what hub as has no markings but looks like a lx one I had on a previous bike. Plastic pedals, kona racelight bars and saddle, velocity stem, p2 forks. Everything else is as it came from the shop 20 odd years ago. I've no reason to lie, it's not like I've built it myself or changing parts to be a weight weenie. I was just surprised at how close it is to some builds where people are trying to get as light as possible and spent quite a bit of money doing so.

Re:

Avoid that place if that is correct, also their calibration should not 'go out' by any large amount to need recalibrating that regularly unless they are after pinpoint precision.

Either that or your at the bottom or top of its measurement range.

Your baggage scale is probably the most accurate for a bike.

Are you sure it wasn't 31lb which a Hahana with bloat could easily be.

Re:

25lb is more realistic.

Rigid I assume, anyway the forum needs pictures of the bike. That's the important thing and a 'build' thread

Talking of scales, anybody recommend an accurate decent hang up one for measuring luggage maybe even bikes

Those people who spend quite a lot of money doing it also spend a fair bit on accurate scales.
I used to use the lab scales at work (accurate to 0.1g up to 500g then something like 0.5g to 2 kilos.) And they were calibrated weekly. And as they were lab scales, they're very very very rarely needed a tweak during calibration. Maybe once or twice a year they'd be out by 1 or 2 10ths of a gram. Not 5 lbs out on a 27.5lb bike.
And calibrated to meet aero industry specification as well. So not scrap metal.
Unless we made a mistake......

Whole bikes used to get weighed either in goods out or one of the other larger scales in the inspection shops.
Again. Meticulously accurate as having a gas turbine engine out of balance or over weight is serious stuff.

Used to get in trouble sometimes. But it was worth it.

Yeah, tried the £10 Chinese cheapo digi ones, got screwed by Ryanair. Next set will be much more accurate... hopefully ! Like the look of these ones but one of the reviews stated the reading varies by upto 300g on a full bike :?
