If I remember correctly, it's a typical 105 MIX. Still a smoking deal, but don't want anyone mislead. I am LOVING my new R230. I wanted the more "comfort" oriented bike, so I'm still glad I made the choice that I did over the 330, but that IS a great deal! And yes, Don is a trouble maker, disguising his dastardly plan as offering a great product and amazing customer service!
