I'm wondering if you could build a bike using locally made components from top to bottom (locally meaning UK, Ireland and the rest of western Europe)
I'm guessing that there may be problems when it comes to raw materials and a bit of leeway may have to be given, but could it be done?
Hope brakes, hubs
Michelin/Hutchinson tyres (Schwalbe?)
Some Sram stuff is still made in Germany, but which bits? Anyone?
