I've searched the site and can't seem to find what I'm looking for.
There are a lot of discussions about weight. But I can't find any that give an over all view of the percentage of total weight each major component makes up.
For example if a given bike weighs 20lbs what percentage of that is made up of the frame (4 pound frame would be 20%).
Maybe I can't find it because it is so different for any given bike. But still it seems to me like there should be some general rule of thumb info out there.
Why am I asking? I'm thinking about building up an old beater fixed gear bike. This would be my first attempt at building a bike. I'd like for the bike to not end up weighing 40lbs, but if I'm buying parts piece by piece, the frame off of an old Schwinn (that weighted 40lbs or so) is a lot cheaper than something "fancy" (ie light).
