Ah the contemporary weight weeny project...that's pretty exceptional to say the least. Yep, read all about that. But that is NOT a standard 'most people can buy it' rig.
18 bikes No9 = 29.7 lbs
Shand Shug = 29.1 lbs
Stanton Switch9er = 30.4 lbs
These are pretty standard weights these days and even then are considered pretty expensive, up-market bikes, and certainly so to the person on the Clapham Omnibus. And quite a bit more porky than I was riding in the 1990s. I am simple pointing out an historical change, I am NOT complaining, since I love contemporary bikes. And it simply means I have to be a more fit, which is no bad thing.
