How much does your bike weigh?

I think there should be different classes based on rider weight.

For example a 55 kg rider will be able to get away with a much lighter bike than a 120kg rider.

yeah sewanees are renowned for snappage/failure, nice short travel bike though.
my condor somehow is 7.5 which is amazing considering the amount of tubing in it! (62cm)

I would suggest a 120kg should be looking at their own weight before worrying about the bike :-)

I am a bit of a weight weenie and this year decided to see if I could get my weight down. I managed to lose 7kg and get down to 70kg which for me is fairly lean at 178cm.
The point of the story is that it hasn't really made any noticeable difference when riding (possibly slightly faster uphill but that just because I am fitter than in the winter) yet 7kg is the weight of a whole bike.
But for some reason I am still obsessing a bit over a few hundred grams on wheels, forks etc,. so it is clearly a mental issue!

Ah, but rotational weight is worth more than any other sort, so (ignoring any fitness implications) you're better off saving 300g on your wheels than on your body.

Agree, but be hard pushed to lose 7kg from your rims/tyres/spokes!

The point is, 7kg wasn't noticeable, so why do I bother spending more on a part that is maybe 200 grams less than a cheaper one. Question for myself obviously :-)

Do your legs not rotate when you pedal?

If you can produce the same power after weight loss, it's always better to lose the weight from body not bike. There are more advantages than just the weight (it's cheaper to lose body weight, you get better heat management, your heart has to pump blood to less tissue so you're more efficient, etc). If you lose body weight you can STILL have a lighter bike too.

Fecking Ahmen to that!

I've bought some veloplugs for a 29er wheelset* I'm putting together. A possible 15g saved per wheel, I'm going to be flying up those hills** ;)

(*I'm probably give tubeless a bash at some point, so rim tape would be removed sooner or later anyway. Mght even put the NoTubes strip over the plugs. Belt + braces = good)
(**That not to say I dont have a problem)

Well, I caveated it by stating that I was ignoring any fitness benefits to the weight loss, so it's then just a question of the pedalling thing.

Basically, as your cranks are smaller than your wheels, your feet are turning smaller circles than the tyres, which is where the difference in advantage comes in. Obviously hubs and bottoms brackets offer a much lower benefit than rims/pedals/tyres.

Haven't seen that for a while !

I designed that 'light-bikes.com' logo a few years ago (may be as far back as 2001/2002 ??)

Was that your pre-pooh period?

Both weighed as shown:

Diamant = 9.25kg / 20.4lbs

Mercian = 12.75kg / 28.1lbs

i think it weighs the same as my dartboard... without the chain and chainset.

Like 120g is not light enough some nutter has tuned a Lightweight rear mech down to 91g.

May as well just have a dump.

I can't tell what he's changed? You can bet that a person like that will have a dump too.

I dont think the original has carbon sprockets, and he may have swapped the bolts for alu. I assume it comes with Ti bolts though so thats not much of a saving.

looks like a custom back plate, different weave/thickness to the front one

People like that must be great fun at parties >_>

anyone who weighs their bike.

Or their turds.

anyone who weighs their bike.
And?

......must be great fun at parties

they are pretty good fun to have at bike weighing parties

I was questioning your assertion. Am I fun at parties?
Is BringMe fun at parties?

Don't worry. Just answered my own question...

ha! i knew what you meant
