Done quite a bit of Googling on this new groupset but can't seem to find an ounce of info. Does anyone know what's going on with it? Availability was supposed to be August. Now I'm hearing they're not shipping till late September. No advance reviews available from the big websites, and the only information around in articles appears to be generic 'what's new?' regurgitation of Shimano's official marketing releases. Even Shimano' s website has censored all info aside from their marketing splash page, and blank pages for most of the componentry. Does anyone know what's going on?
