Just bought a set of digital fishing scales to get this sorted. 31lb 5 oz. Trigger 29 medium, lefty Supermax, tubed Hans Damfs. Dropper post. Genuinely surprised, thought the bathroom scales were close.

Steel Genesis ioid SS with light wheels is about 13kg
Nice road is 7.25kg without trying hard
Race bike is 7.8 kg
Steel commuting fixed wheel is 9kg summer and 10 kg winter.

I like bikes to feel light, but am not obsessive. The Nice bike could easily drop a kilo with Dura Ace and light carbon tubular wheels. It's the lightest frame Giant make. But it "feels" light enough already.

The SS is not that light, but I get it up hills by throwing it around OK

LBS scales, are they all deliberately calibrated to under read to please customers? 🙂

Dont think so mate same scales weighed my naked soul frame @ 2.1kg which is bang on the higher side of the estimated weight

Presuming your scales give a linear reading and that the manufacturer met the designers specs.

Chromed 456 with alfine, xm819 and rc41f was half an ounce under 32lb on about an accurate scale as you can get, MT KC300.

I think your bike shop needs to calibrate their scales properly.

Compare than to my carbon zesty, in a similar spec, and i can't quite see where you have lost an entire KG??

(unless the entire frame only weighs 1kg............)

Just got back from p a curry and was sad enough to think " ooh! Why not weigh the commuter?"
Giant Escape 2. Flat bars and V8s. 26lb 3oz.

Not quite got the nerve to suggest Lucy tries the scales. I'm sure she 'knows' her weight.

All mine were weighed with the super accurate my weight + bike weight on the bathroom scales method.

XC race: 10.5kg
Rigid SS: 10.1kg
Road: 9.5kg

For a laugh I worked out that if I spent enough I could drop ~740g from the race bike without getting anything too exotic.

Pivot Mach6 (Medium frame) with 160mm Pikes, XX1 and XTR build.

12.28kg with pedals which is not too bad considering it wasn't spec'd for weight saving, its cheaper and healthier for me to lose weight anyway.

I think scales are the main culprit. +/- 2% on a 24lb bike would mean a difference of nigh on a whole pound between an optimistic set and a pessimistic set. I've calibrated digital scales that have proven to be much worse.

I thought my Big Top would come out over 26lbs as the claimed frame weight of 4.4lbs was actually 4.8... So I was pleasantly surprised by 24.78lbs. (It may be a bit heavier now as I've changed saddle and tyres since this shot was taken). No matter how light, it still feels like it weighs a ton when I'm knackered and faced with another bloody wet root strep-up...

10.83kg on my cheap Chinese eBay scale.
Not the lightest rims and I could swap for a carbon seat post and smaller discs and lose the bar ends, but other than that, I reckon it's about as light as you can go for a metal frame.

Hi Max,

I don't think the bikes are a similar spec;

XT/XTR mix v XX1
Crossmax ST wheels v SRAM Roam 60 carbons
Formula R1 w/ 200 & 180mm rotors v X0 Trail w/ 180 & 160mm rotors
V8 pedals v XTR Trail

Easily a whole kg there at least.

The 28.6lb weight of my zesty is with placcy nukeproof pedals, not the V8s, and XX1 cranks with XTR+42T cassette

A kilogram where? The wheels, pedals and brakes weigh much the same. Given the above info there can't be more than about 200g extra weight in those 3 combined.

14.3kg / 31.5lbs for this:

I just got curious about where weight could be saved: The Super Gravity Magic Mary is a bit of a beast, the SLX double+bash cranks are pretty solid, the CCDBair is a lot heavier than a smaller shock, and the Flow EX rims are on the burlier side for this bike. Swap them for appropriate but lighter parts and that would knock off just over a kilo. Take the pedals off for magazine weights and it's down to 12.8kg / 28.1lbs.

But it climbs better than my 26.5lb hardtail so I really can't see the point of any changes!

20.35lbs on the scales... scalpel 3 carbon with 650b wheels, size large and a 1x10 set up.

Oooooh! Nice.
Love the big green cog. And what rotors are those?

Yea but what does it weigh with sensible tyres on 😉

the rotors are these:- http://www.xcracer.com/shop/viewproduct.php?productid=299 ... they work so much better than the alligator windcutters i have used before.

as for the tyres... with ra-ra or ra-ro combo maybe a couple of hundred grams more. my reasoning for fitting them was more about clearance on the seatstay when fitting 650b wheels... with the thunder burts, there is very respectable clearance and they roll as fast as a fast thing.

i have a yeti sb-66 for gnarly stuff, so can be quite xc focussed with the scalpel.

So how much slower uphill is the SB66 (and what does it weigh)?

I haven't weighed the SB66 yet but it's not light. The frame is very heavy indeed even if the rest of the build isn't (pikes, arch ex/hopes, 1x10, haven carbon, reverb etc etc) BUT it does climb seem like a mountain goat, certainly better than the ASR5 which came before it, which was a disappointment against the Turner Flux that came before that.

I'm quite sure the Cannondale will romp away on the ups and the flats, but on the downs, the SB-66 magic really comes into play.

32.5lbs on scales that are calibrated every 6 months. I always think people's weight claims are always on the optimistic side.

the cranks themselves really aren't that heavy - they're only 20g or so heavier than Xt cranks.

But the slx bash-ring weighs about 200g, which is a *bit* hefty.

ace looking bike btw!

Mine is a claimed 31.8lbs / 14.4 kg's. Pretty happy with that to be fair as I haven't made any concious attempt to slim it down. My last bike was comparable to the weight of a small moon so this one feels pretty lightweight to me.

28lbs on the button for my ragley mmmbop - 150mm pikes, hope\mavic 719 wheels, slx\xt drivetrain, hope tech brakes & reverb

Interesting to see so many AM FS bikes weighing similar/less, seems I'd need to spend a fortune if I upgraded to a FS frame and wanted to keep the weight similar.

Can finally join in as picked up from lbs and got them to weigh it.

Tallboy LTC in XXL, X01 drivetrain, reverb, crossmax STs and Pikes came in at 12.7kg with pedals, happy with that for a bike bike 🙂

I always love the "Just Under" guestimates [I]"its Just a sliver under 24.9lbs"[/I]... is it bollocks! its 28lbs and you know it.

My 456 was 32lbs last time I weighed it but it has since acquired a heavier fork, front wheel and gone from 2x9 to 1x10 drive and I cleaned some mud off it... I reckon its probably gained a pound and a half...

Don't know or care what my other bikes weigh, they are mostly heavier than other peoples I like to think that makes me much more manly (While giving a perfect excuse for being a bit slow on climbs)...

9kg flat on the shop scales.
Seems about right - WC ones are 8.8kg with lighter wheels but heavier tyres.

My 96 was 22lbs with 2x10, so that seems about right!
