I bought a few spanners for my MuP8 - a few of the nuts need tightening - but found that none of my metric spanners fit them. The the penny dropped. Doh! Dahons are American bikes hence the nuts aren't metric, so I guess they're imperial? Is there a difference between UK and US imperial sizes or are they one and the same?
Why don't Dahon supply a few spanners or some sort of small toolkit with their bikes?
