Measuring weight of bike

[Paddy]

I think you missed my point :>) rounding up to the nearest ton would be more useful.

got you...  :-[

on a honest note, I found 2 guys on another forum debating about where to find the next 50 grams to be removed off the bike weight...

Don't eat breakfast and have a dump before you head for the track

I trust they did that already. for me, I still can lose more than my bike without getting fragile (or getting close to it ...)  :-[

it was a pleasure to read your replies, 

thanks for the hints, the typo has been rectified.

He may be  (clever) but reckon he's telling porkies about it being a shrunk SuperDuke............ myth busted!

chrisk, I try to be as honest as possible , here is a photo showing the SuperDuke just arrived as kit bike. It was a very special day, you can imagine.

Delivered separately has been a toolbox containing all three neccessary tools for assembly and maintenance. Very cool.

Unfortunately, after shrinking the bike I could not find those tools anymore.

Question: If I shrink plastic it still weighs the same amount as before it was shrunk, why then does the SuperDuke, when shrunk, weigh so little?

chrisk, it took a whole night to shrink that thing in my little do-it-yourself shrinking machine. The next morning there was a huge cloud of water vapour in the rooms and also outside. The duke was 197(!) kg before, and 197 g after, so I assume, it consists of 99,9% water. Never realised that.

Not real keen on those tyre profiles either

Also never realised that. Here in northern Germany almost all streets are straight. I suspect it is now to late for customer complaints 

One setup was missing though to 100% proof that: remove the book on the last two pics and repeat the measuring of front and rear and add them up. I suppose the sume will be way below 197g, right?

Lothar, I agree with you 100%. I took also photos of that setup, but did fear to show them...

again 197 g ...

I see you found the toolbox

Seems your SuperDuke is a water duc.

Clearly, the factory is using a plastic with too greater WVTR (Water Vapour Transmition Rate).
They need to use a different blend. I suggest; based on ASTM E96, a WVTR of 1.6g/m2/24h at 38d C @ 100%RH or greater, should reduce the water ingress somewhat.

Looking at your shrunk item, they do seem to have gotten the free shrink rate down to a tee though.

Am i the only one that is concerned that this jens chap appears to be sporting a mullet?
No offence like, just an observation

yeah - but now with the tool-box on the scale, too...  can you measure it like that without the toolbox, please (and without anything else adding to the real weight?  ) thanks...

hi padlock,

no remarkable extensions at the back of the head. Only a visual illusion.

Lothar, here you are:

Yeah, but your shirt needs ironing!
