Err, lets have it right, at the end of the day it only shows what spending on advertizing can do , don't know why your all so suprised .
I know you don't really buy too many bad bikes nowadays , but most reviews very rarely knock a bike , The testers and writers are very wary with what trhey say , because after all you will not keep your job long, or get to test many bikes if the manufacturers say to the editor , You can test any of our bikes BUT BLA BLA is'nt riding it or we refuse to give you bikes .
Editors are not stupid they know they have to have a broad range to choose from . and advertizing dollars speak volumes. .
My guess is they take turns.
