Re: Re:

The Bike name? You can google Krapf bicycle,in the image section there are a few.I think it is a Swiss brand.

So, it is 19.7/ 8.95kg in the picture and i want it down at 8.60.Still can go lower if you have money,but i want it retro and usable.

That's a good weight for a vintage bike. Are the quick release skewers modern external cam type? If so it may be worth reading the info on the Sheldon Brown web site. See link.

That seatpost looks like a heavyweight - a careful change should see you shed some good weight. Likewise some Veloflex master tyres, and then that back wheel isn't the lightest thing in the world

Oh yess,rear wheel is like 1140gr naked.I will go for something like 900gr or less.
Seatpost is ok-ish cut to size.But it is cheap and ugly, want to change it.Problem is its 27.0mm the popular size is 27.2(dosn't fit my frame)
Veloflex Master 23 is looking good.

Are the quick release screwers modern external cam type?

-Saddle from SMP Composit to SMP Evolution
- Bottle Elite Eroica Vintage, and Elite Ciussi Inox bottle cage.(Much nicer this way)

You could probably trim the brake cables for a few grams!
